Description

驱动器和终端设备 技术领域
本申请涉及终端技术领域，尤其涉及一种驱动器和终端设备。
背景技术
电活性聚合物具有结构简单、能量密度高、轻便、无噪音、柔性等优点，在受到电刺激后可以产生形变，将电能转化为机械能。因此，电活性聚合物可以用作能量转化器，例如驱动器。
现有技术中，在电场驱动下，电活性聚合物不能完全填满驱动器中阳极的所有空隙，驱动器中的实际形变电活性聚合物量小于理论形变率。因此，驱动器中电活性聚合物的形变率仍有待提升。
发明内容
为了解决上述技术问题，本申请提供一种驱动器和终端设备，可以充分利用阳极中的网孔，提高第一电活性聚合物和第二电活性聚合物的实际形变率，从而提高驱动器的形变率。
第一方面，本申请提供一种驱动器，该驱动器包括驱动单元，驱动单元包括依次层叠设置的第一阴极、第一电活性聚合物、阳极、第二电活性聚合物、以及第二阴极。沿第一阴极指向阳极的方向，阳极包括依次层叠设置、且电连接的第一阳极、第二阳极、以及第三阳极；第一阳极和第三阳极为导电纱网，导电纱网包括多个网孔；第二阳极为无孔导电板。
在对第一阴极、阳极、第二阴极充电时，第一阳极的网丝带正电荷，第一电活性聚合物在靠近阳极侧带负电荷，因此，第一阳极的网丝与第一电活性聚合物相互吸引，第一电活性聚合物沿着第一阳极的网丝表面发生蠕变，并钻进第一阳极的网孔中。同理，第三阳极的网丝带正电荷，第二电活性聚合物在靠近阳极侧带负电荷，因此，第三阳极的网丝与第二电活性聚合物相互吸引，第二电活性聚合物沿着第三阳极的网丝表面发生蠕变，并钻进第三阳极的网孔中。
在此基础上，由于阳极除了包括第一阳极和第三阳极以外，还包括设置于第一阳极和第三阳极之间的第二阳极，并且，第二阳极所带的正电荷，与其两侧的第一电活性聚合物和第二电活性聚合物的负电荷富集层电性相反，因此，在第一阳极的网孔位置处，第二阳极与第一电活性聚合物相互吸引，第一电活性聚合物不断向第二阳极(也可以说，第一阳极的网孔)处聚集，并钻进第一阳极的网孔中。在第三阳极的网孔位置处，第二阳极与第二电活性聚合物相互吸引，第二电活性聚合物不断向第二阳极(也可以说，第三阳极的网孔)处聚集，并钻进第三阳极的网孔中。相较于相关技术的第一电活性聚合物和第二电活性聚合物在阳极的网孔处互相排斥，不能填满阳极的网孔，本申请实施例可 以利用第二阳极充分吸引第一电活性聚合物，并使第一电活性聚合物在第一阳极的网孔处聚集，充分吸引第二电活性聚合物在第三阳极的网孔处聚集，从而可以充分填满第一阳极和第三阳极的网孔，提高第一电活性聚合物和第二电活性聚合物的实际形变率，从而提高驱动器的形变率。
在一些可能实现的方式中，第一阳极包括间隔设置的多根第一导电网丝和间隔设置的多根第二导电网丝，多根第一导电网丝与多根第二导电网丝交结成网。第三阳极包括间隔设置的多根第三导电网丝和间隔设置的多根第四导电网丝，多根第三导电网丝与多根第四导电网丝交结成网。在对第一阴极、阳极、第二阴极充电时，由于第二阳极与第一电活性聚合物的电性相反，因此，第一电活性聚合物可以充分填满第一导电网丝与第二导电网丝构成的网孔中；由于第二阳极与第二电活性聚合物的电性相反，因此，第二电活性聚合物可以充分填满第三导电网丝与第四导电网丝构成的网孔中。
在一些可能实现的方式中，第一阳极与第三阳极的形状和尺寸相同。这样一来，任一第一阳极的一根第一导电网丝在第一阴极上的正投影，均与第三阳极的一根第三导电网丝在第一阴极上的正投影重合。任一第一阳极的一根第二导电网丝在第一阴极上的正投影，均与第三阳极的一根第四导电网丝在第一阴极上的正投影重合。
在另一些可能实现的方式中，无论第一阳极与第三阳极的形状和尺寸是否相同，多根第一导电网丝在第一阴极上的正投影，均与多根第三导电网丝在第一阴极上的正投影错开设置。多根第二导电网丝在第一阴极上的正投影，均与多根第四导电网丝在第一阴极上的正投影错开设置。
在一些可能实现的方式中，第一电活性聚合物和第二电活性聚合物包括聚氯乙烯凝胶；和/或，第一阳极和第三阳极的材料包括不锈钢或铜镍合金；和/或，第二阳极、第一阴极、以及第二阴极的材料包括铝箔。当然，上述结构的材料还可以是其他，本申请对此不作限定。
在一些可能实现的方式中，第一阳极和第三阳极的目数范围为50～200目，即，第一阳极和第三阳极中，每一英寸*一英寸范围内，有50～200个网孔；和/或，沿第一阴极指向阳极的方向，第一阳极和第三阳极的厚度范围为50μm～300μm；和/或，沿第一阴极指向阳极的方向，第二阳极的厚度范围小于或等于30μm。
当然，对于不同尺寸的驱动器，第一阳极和第三阳极的目数范围、第一阳极、第二阳极、以及第三阳极的厚度范围，还可以是其他，本申请不作限定。
在一些可能实现的方式中，驱动单元的数量为多个，沿第一阴极指向阳极的方向，多个驱动单元层叠设置，从而提高驱动器形变位移量。由于在电场作用下，所有驱动单元的第一阴极和第二阴极均带负电荷，因此，任一驱动单元的第二阴极，可以复用作与其层叠设置且相邻的驱动单元的第一阴极。
第二方面，本申请提供一种驱动器，该驱动器包括驱动单元，驱动单元包括依次层叠设置的第一阴极、第一电活性聚合物、阳极、第二电活性聚合物、以及第二阴极。沿第一阴极指向阳极的方向，阳极包括依次层叠设置、且电连接的第一阳极和第二阳极。第一阳极包括间隔设置的多根第一导电网丝和间隔设置的多根第二导电网丝，多根第一导电网丝与多根第二导电网丝交结成网；第二阳极包括间隔设置的多根第三导电网丝和间 隔设置的多根第四导电网丝，多根第三导电网丝与多根第四导电网丝交结成网。多个第一导电网丝在第一阴极上的正投影，均与多根第三导电网丝在第一阴极上的正投影错开设置；第二导电网丝在第一阴极上的正投影，均与多根第四导电网丝在第一阴极上的正投影错开设置。
在利用控制电路对第一阴极、阳极、第二阴极充电时，第一阳极的网丝带正电荷，第一电活性聚合物在靠近第一阳极侧带负电荷，因此，第一阳极的网丝与第一电活性聚合物相互吸引，第一电活性聚合物沿着第一阳极的网丝表面发生蠕变，并钻进第一阳极的网孔中。同理，第二阳极的网丝带正电荷，第二电活性聚合物在靠近第二阳极侧带负电荷，因此，第二阳极的网丝与第二电活性聚合物相互吸引，第二电活性聚合物沿着第二阳极的网丝表面发生蠕变，并钻进第二阳极的网孔中。
在此基础上，对于一体化交结成网的多根第一导电网丝和多根第二导电网丝，以及一体化交结成网的多根第三导电网丝和多根第四导电网丝，由于多个第一导电网丝在第一阴极上的正投影，均与多根第三导电网丝在第一阴极上的正投影错开设置。第二导电网丝在第一阴极上的正投影，均与多根第四导电网丝在第一阴极上的正投影错开设置。因此，在第一阳极的网孔与第二阳极在第一阴极的投影重合位置处，第二阳极与第一电活性聚合物相互吸引，第一电活性聚合物不断向第二阳极(即，第一阳极的网孔)处聚集，并钻进第一阳极的网孔中。在第二阳极的网孔与第一阳极在第一阴极的投影重合位置处，第一阳极与第二电活性聚合物相互吸引，第二电活性聚合物不断向第一阳极(即，第二阳极的网孔)处聚集，并钻进第一阳极的网孔中。相较于相关技术的第一电活性聚合物和第二电活性聚合物在阳极的网孔处互相排斥，没有充分填满阳极的网孔。本申请实施例可以利用第二阳极吸引第一电活性聚合物，促使第一电活性聚合物钻进第一阳极的网孔中；利用第一阳极吸引第二电活性聚合物，促使第二电活性聚合物钻进第二阳极的网孔中，提高第一电活性聚合物和第二电活性聚合物的实际形变率。
对于采用平结交结成网的多根第一导电网丝和多根第二导电网丝，以及采用平结交结成网的多根第三导电网丝和多根第四导电网丝，沿任一第一导电网丝指向与其相邻的第一导电网丝的方向，或者，沿任一第二导电网丝指向与其相邻的第二导电网丝的方向，第一导电网丝、第三导电网丝、第二导电网丝、以及第四导电网丝依次交错设置。
在利用控制电路对第一阴极、阳极、第二阴极充电时，第一电活性聚合物和第二电活性聚合物分别沿着附近的第一阳极和第二阳极表面蠕变，分别钻进第一阳极和第二阳极的网孔中。当第一电活性聚合物钻进第三导电网丝和第四导电网丝之间的间隙中时，处于第三导电网丝和第四导电网丝之间的第一导电网丝和第二导电网丝均促进了第一电活性聚合物进一步向第三导电网丝与第四导电网丝之间的网孔中聚集。同样的，当第二电活性聚合物钻进第一导电网丝和第二导电网丝之间的间隙中时，处于第一导电网丝和第二导电网丝之间的第三导电网丝和第四导电网丝均促进了第二电活性聚合物进一步向第一导电网丝与第二导电网丝之间的网孔中聚集。相较于相关技术的第一电活性聚合物和第二电活性聚合物在阳极的网孔处互相排斥，没有充分填满阳极的网孔。本申请实施例可以提高第一电活性聚合物和第二电活性聚合物的实际形变率。
在一些可能实现的方式中，沿第一阴极指向阳极的方向，第一导电网丝与第二导电 网丝交结处的厚度，与第一导电网丝和第二导电网丝相同。沿第一阴极指向阳极的方向，第三导电网丝与第四导电网丝交结处的厚度，与第三导电网丝和第四导电网丝的厚度相同。即，第一导电网丝和第二导电网丝一体化交结成网，第三导电网丝与第四导电网丝一体化交结成网。
在一些可能实现的方式中，第一阳极与第二阳极的形状和尺寸相同。当然，第一阳极与第二阳极的形状和尺寸也可以不同，本申请对此不作限定。
在一些可能实现的方式中，第一导电网丝的中心在第一阴极上的正投影，与相邻两个第三导电网丝在第一阴极上的正投影连线的中心重合。第二导电网丝的中心在第一阴极上的正投影，与相邻两个第四导电网丝在第一阴极上的正投影连线的中心重合。这样一来，在第一阳极的网孔与第二阳极在第一阴极的投影重合位置处，可以利用第二阳极最大程度吸引第一电活性聚合物向第一阳极的网孔处移动并聚集；在第二阳极的网孔与第一阳极在第一阴极的投影重合位置处，可以利用第一阳极最大程度吸引第二电活性聚合物向第二阳极的网孔处移动并聚集。
在一些可能实现的方式中，第一电活性聚合物和第二电活性聚合物包括聚氯乙烯凝胶；和/或，阳极的材料包括不锈钢或铜镍合金；和/或，第一阴极和第二阴极的材料包括铝箔。当然，上述结构的材料还可以是其他，本申请对此不作限定。
在一些可能实现的方式中，第一阳极和第二阳极的目数范围为50～200目，即，第一阳极和第二阳极中，每一英寸*一英寸范围内，有50～200个网孔；和/或，沿第一阴极指向阳极的方向，第一阳极和第二阳极的厚度范围为50μm～300μm。
当然，对于不同尺寸的驱动器，第一阳极和第三阳极的目数范围、第一阳极、第二阳极、以及第三阳极的厚度范围，还可以是其他，本申请不作限定。
在一些可能实现的方式中，驱动单元的数量为多个，沿第一阴极指向阳极的方向，多个驱动单元层叠设置，从而提高驱动器形变位移量。由于在电场作用下，所有驱动单元的第一阴极和第二阴极均带负电荷，因此，任一驱动单元的第二阴极，可以复用作与其层叠设置且相邻的驱动单元的第一阴极。
第三方面，本申请提供一种终端设备，终端设备包括控制电路、以及第一方面或第二方面的驱动器；控制电路，用于在驱动器工作时，为驱动器的第一阴极第二阴极、以及阳极供电。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
本申请实施例的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一目标对象和第二目标对象等是用于区别不同的目标对象，而不是用于描述目标对象的特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例的描述中，除非另有说明，“多个”的含义是指两个或两个以上。例如，多个处理单元是指两个或两个以上的处理单元；多个系统是指两个或两个以上的系统。
本申请实施例提供一种终端设备，上述终端设备可以是智能仿生、柔性机器人、航空航天、智能医疗器件、可穿戴设备等包含电活性聚合物的设备。当然，终端还可以是其他设备，本申请实施例不对终端设备的具体形式进行限定。
以终端设备为智能仿生的人工肌肉为例，应用于致动器的电活性聚合物具有应变高、柔软性好、轻便、无噪声等优点。例如，电活性聚合物可以为聚氯乙烯(poly vinylchloride，PVC)凝胶，由其制备而成的驱动器具有与人类肌肉相比拟的形变率、力学强度和响应速度，且驱动电压一般低于400V，可以用于制作人工肌肉。在对致动器充电和去电的情况下，电活性聚合物可以发生弹性形变，实现人工肌肉的收缩和舒张。
终端设备除了包括驱动器以外，还可以包括控制电路。可以利用控制电路对第一阴极、第二阴极、以及阳极进行充、放电，以使得驱动器发生形变。
控制电路可以通过开关与驱动器电连接，如图1b所示，在无需利用控制电路为驱动器的第一阴极11、第二阴极15、以及阳极13进行充电时，开关可以断开。在需要利用控制电路为驱动器的第一阴极11、第二阴极15、以及阳极13进行充电时，开关可以导通。
例如，相关技术中，驱动器可以包括至少一个驱动单元，叠层型PVC凝胶制备而成的驱动器是驱动器的主要形式，如图1a和图1b所示，驱动单元10包括依次层叠设置的第一阴极11、第一电活性聚合物12、阳极13、第二电活性聚合物14、以及第二阴极15。其中，第一阴极11和第二阴极15呈平面状；阳极13呈网孔状，阳极13包括多根网丝，多根网丝交结成网；第一电活性聚合物12和第二电活性聚合物14可以是PVC凝胶。
在利用控制电路对第一阴极11、阳极13、以及第二阴极15充电时，第一电活性聚合物12和第二电活性聚合物14中的塑化剂可以分别携带来自第一阴极11和第二阴极15的负电荷，并分别聚集在第一电活性聚合物12和第二电活性聚合物14靠近阳极13侧，形成负电荷富集层。如图1c所示，由于静电力作用，阳极13附近的第一电活性聚合物12和第二电活性聚合物沿着阳极13的网丝表面蠕动，部分钻进网孔空隙中，从而实现驱动单元10在厚度方向上压缩。停止对第一阴极11、阳极13、以及第二阴极15充电(也可以说，去电)时，由于第一电活性聚合物12和第二电活性聚合物自身回弹力的作用，第一电活性聚合物12和第二电活性聚合物恢复为原有的形态，驱动单元10也恢复初始厚度。这样一来，通过循环充放电，可以实现驱动单元10在厚度方向上的往复形变。
此处，驱动单元10的厚度方向，可以是第一阴极11指向阳极13的方向，下文提到的任一结构的厚度，均为该结构在厚度方向上的厚度。并且，对于本申请实施例，第一电活性聚合物12和第二电活性聚合物14还可以是除了PVC凝胶以外的其他材料，只要其工作原理，与第一电活性聚合物12和第二电活性聚合物14为PVC凝胶时的工作原理相同即可。为了方便描述，下文均以第一电活性聚合物12和第二电活性聚合物14为PVC凝胶为例进行说明。
然而，发明人发现，相关技术中，驱动器的实际形变率远小于理论形变率。以目数为100目、厚度为180μm、空隙率为72％的阳极13，以及厚度为200μm的PVC凝胶为例，在电场作用下，驱动器的实际最大形变率约为11％。而经计算，当PVC凝胶填充满整个 阳极13网孔的空隙时，驱动器的理论形变量可以达到22％，远超实际的形变率。这一结果表明PVC凝胶并没有充分填满阳极13的网孔，阳极13网孔没有被充分利用，驱动器的形变率还有很大提升空间。
如图1c所示，发明人分析PVC凝胶不能充分填满阳极13网孔的原因，是由于在电场作用下，沿厚度方向，阳极13附近的PVC凝胶(即，第一电活性聚合物和第二电活性聚合物)在朝向网孔中间蠕变过程中互相排斥，随着阳极13两侧的PVC凝胶之间的间隙越来越小，PVC凝胶负电荷富集层之间的静电斥力越来越大。
如图2a-图3c所示，本申请实施例提供一种驱动器，通过对阳极13的结构进行改进，以在电场作用下，减小阳极13网孔处第一电活性聚合物12和第二电活性聚合物14间的斥力。
该驱动器包括驱动单元10，驱动单元10包括依次层叠设置的第一阴极11、第一电活性聚合物12、阳极13、第二电活性聚合物14、第二阴极15。除此以外，沿第一阴极11指向阳极13的方向，阳极13包括依次层叠设置、且电连接的第一阳极131、第二阳极132、以及第三阳极133。第一阳极131和第三阳极133为导电纱网，导电纱网包括多个网孔，第二阳极132为无孔导电板。
在一些可能实现的方式中，如图2a和图3a所示，第一阳极131和第三阳极133的网孔可以由多根网丝交结而成。
可选的，第一阳极131包括间隔设置的多根第一导电网丝1311和间隔设置的多根第二导电网丝1312，多根第一导电网丝1311与多根第二导电网丝1312交结成网。第三阳极133包括间隔设置的多根第三导电网丝1331和间隔设置的多根第四导电网丝1332，多根第三导电网丝1331与多根第四导电网丝1332交结成网。
此处，第一导电网丝1311的厚度与第二导电网丝1312的厚度可以相同，也可以不相同。第三导电网丝1331的厚度与第四导电网丝1332的厚度可以相同，也可以不相同。为了方便描述，下文均以第一导电网丝1311的厚度与第二导电网丝1312的厚度相同，第三导电网丝1331的厚度与第四导电网丝1332的厚度相同为例进行说明。
在一些可能实现的方式中，本申请实施例不对第一阳极131的多根第一导电网丝1311和多根第二导电网丝1312的交结方式，以及第三阳极133的多根第三导电网丝1331和多根第四导电网丝1332的交结方式进行限定。
可选的，多根第一导电网丝1311和多根第二导电网丝1312可以采用平结、或斜结、或一体化交结成网。多根第三导电网丝1331和多根第四导电网丝1332可以采用平结、或斜结、或一体化交结成网。当然，还可以采用其他方式交结成网，本申请实施例对此不作限定。
例如，如图2a和图2b所示，多根第一导电网丝1311和多根第二导电网丝1312采用平结交结成网。第一导电网丝1311与第二导电网丝1312的交结处的厚度，是第一导电网丝1311和第二导电网丝1312的厚度之和。在第一导电网丝1311的厚度与第二导电网丝1312的厚度相同的情况下，第一导电网丝1311与第二导电网丝1312的交结处的厚度，可以是第一导电网丝1311的厚度的两倍，也可以是第二导电网丝1312的厚度的两倍。
如图2a和图2b所示，多根第三导电网丝1331和多根第四导电网丝1332采用平结交结成网。第三导电网丝1331与第四导电网丝1332的交结处的厚度，是第三导电网丝1331和第四导电网丝1332的厚度之和。在第三导电网丝1331的厚度与第四导电网丝1332的厚度相同的情况下，第三导电网丝1331与第四导电网丝1332的交结处的厚度，可以是第三导电网丝1331的厚度的两倍，也可以是第四导电网丝1332的厚度的两倍。
又例如，如图3a和图3b所示，多根第一导电网丝1311和多根第二导电网丝1312一体化交结成网。第一导电网丝1311与第二导电网丝1312的交结处的厚度，与第一导电网丝1311的厚度和第二导电网丝1312的厚度均相同。
如图3a和图3b所示，多根第三导电网丝1331和多根第四导电网丝1332一体化交结成网。第三导电网丝1331与第四导电网丝1332的交结处的厚度，与第三导电网丝1331的厚度和第四导电网丝1332的厚度均相同。
在一些可能实现的方式中，在驱动器工作时，终端设备的控制电路，可以为第一阴极11、第二阴极15、以及阳极13供电，以满足驱动器工作时的充、放电条件。
此处，由于阳极13的第一阳极131、第二阳极132、以及第三阳极133电连接，因此，在控制电路为阳极13充电的过程中，第一阳极131、第二阳极132、以及第三阳极133均带正电荷。
在一些可能实现的方式中，第二阳极132为无孔导电板，即，第二阳极132可以是平板状，且第二阳极12的表面密封，无网孔。
基于此，本申请实施例提供的驱动单元10的工作原理可以为：在利用控制电路对第一阴极11、阳极13、第二阴极15充电时，第一阳极131的网丝带正电荷，第一电活性聚合物12在靠近阳极13侧带负电荷，因此，第一阳极131的网丝与第一电活性聚合物12相互吸引，第一电活性聚合物12沿着第一阳极131的网丝表面发生蠕变，并钻进第一阳极131的网孔中。同理，第三阳极133的网丝带正电荷，第二电活性聚合物14在靠近阳极13侧带负电荷，因此，第三阳极133的网丝与第二电活性聚合物14相互吸引，第二电活性聚合物14沿着第三阳极133的网丝表面发生蠕变，并钻进第三阳极133的网孔中。
在此基础上，由于阳极13除了包括第一阳极131和第三阳极132以外，还包括设置于第一阳极131和第三阳极133之间的第二阳极132，并且，第二阳极132所带的正电荷，与其两侧的第一电活性聚合物12和第二电活性聚合物14的负电荷富集层电性相反，因此，在第一阳极131的网孔位置处，第二阳极132与第一电活性聚合物12相互吸引，第一电活性聚合物12不断向第二阳极132(也可以说，第一阳极的网孔)处聚集，并钻进第一阳极131的网孔中。在第三阳极133的网孔位置处，第二阳极132与第二电活性聚合物14相互吸引，第二电活性聚合物14不断向第二阳极132(也可以说，第三阳极的网孔)处聚集，并钻进第三阳极133的网孔中。相较于相关技术的第一电活性聚合物12和第二电活性聚合物14在阳极13的网孔处互相排斥，不能填满阳极13的网孔，本申请实施例可以利用第二阳极132充分吸引第一电活性聚合物12，并使第一电活性聚合物12在第一阳极131的网孔处聚集，充分吸引第二电活性聚合物14在第三阳极133的网孔处聚集，从而可以充分填满第一阳极131和第三阳极133的网孔，提高第一电活性聚合物 12和第二电活性聚合物14的实际形变率，从而提高驱动器的形变率。
在一些可能实现的方式中，本申请实施例不对第一阴极11、第一电活性聚合物12、阳极13、第二电活性聚合物14、以及第二阴极15的材料进行限定，只要第一阴极11、阳极13、以及第二阴极13可以导电，第一电活性聚合物12和第二电活性聚合物14可以在电场作用下向阳极13聚集即可。
例如，第一阴极11、第二阴极15、第二阳极132的材料可以是铝箔等。第一阳极131和第三阳极133的材料可以是不锈钢、铜镍合金等。第一电活性聚合物12和第二电活性聚合物14的材料可以是PVC凝胶。
PVC凝胶的制备过程可以是：将邻苯二甲酸二丁酯(dibutyl phthalate，DBA)与四氢呋喃(tetrahydrofuran，THF)混合，并通过磁力搅拌器按照500rpm/min的转速搅拌混合液约1分钟(min)，再缓慢添加PVC粉末到混合液中，其中，DBA与PVC粉末的质量比为4：1，DBA和PVC粉末总质量与THF总质量比为1：2.25，持续搅拌约24小时(h)。将混合液通过涂膜仪制备一定厚度(例如200μm)的薄膜，再通过刀模切割为适用于驱动单元10的尺寸(例如直径28mm的圆形薄膜)。
在一些可能实现的方式中，本申请实施例不对第一阳极131和第三阳极133的目数进行限定，也不对阳极13各层的厚度进行限定。
可选的，第一阳极131和第三阳极133的目数范围可以是50～200目，即，第一阳极131和第三阳极133中，每一英寸*一英寸范围内，有50～200个网孔。此处，第一阳极131的厚度可以与第三阳极133的厚度相同，也可以不相同，本申请实施例对此不作限定。
可选的，第一阳极131和第三阳极133的厚度范围可以是50μm～300μm。第二阳极132的厚度范围可以大于0、小于或等于30μm。例如，第一阳极131和第三阳极133的厚度可以为90μm，第二阳极132的厚度可以为8μm。
在一些可能实现的方式中，第一阳极131与第三阳极133的形状和尺寸可以相同。或者，第一阳极131的形状与第三阳极133的形状相同，第一阳极131的尺寸与第三阳极133的尺寸不同。或者，第一阳极131的形状与第三阳极133的形状不同，第一阳极131的尺寸与第三阳极133的尺寸相同。
无论第一阳极131和第三阳极133的形状和尺寸是否相同，本申请实施例均不对第一阳极131和第三阳极133的相对位置关系进行限定，只要第一阳极131与第三阳极133通过第二阳极132电连接即可。
如图2b所示，在第一阳极131与第三阳极133的形状和尺寸可以相同的情况下，任一第一阳极131的一根第一导电网丝1311在第一阴极11上的正投影，均与第三阳极133的一根第三导电网丝1331在第一阴极11上的正投影重合。任一第一阳极11的一根第二导电网丝1312在第一阴极11上的正投影，均与第三阳极133的一根第四导电网丝1332在第一阴极11上的正投影重合。
或者，如图4所示，无论第一阳极131与第三阳极133的形状和尺寸相同与否，多根第一导电网丝1311在第一阴极11上的正投影，均与多根第三导电网丝1331在第一阴极11上的正投影错开设置。多根第二导电网丝1312在第一阴极11上的正投影，均与多 根第四导电网丝1332在第一阴极11上的正投影错开设置。
而无论多根第一导电网丝1311在第一阴极11上的正投影，与多根第三导电网丝1331在第一阴极11上的正投影重合或错开，多根第二导电网丝1312在第一阴极11上的正投影，与多根第四导电网丝1332在第一阴极11上的正投影错开重合或是错开，均可以利用第二阳极132吸引携带负电荷的第一电活性聚合物12聚集在第一阳极131的网孔中，利用第二阳极132吸引携带负电荷的第二电活性聚合物14聚集在第三阳极133的网孔中。
在一些可能实现的方式中，如图5所示，驱动单元10的数量为多个，沿第一阴极11指向阳极13的方向，多个驱动单元10层叠设置，从而提高驱动器形变位移量。由于在电场作用下，所有驱动单元10的第一阴极11和第二阴极15均带负电荷，因此，任一驱动单元10的第二阴极15，可以复用作与其层叠设置且相邻的驱动单元10的第一阴极11。
下面结合具体示例，计算本申请实施例提供的阳极13的网孔占有率，以及包括多个驱动单元10的驱动器的最大形变率。
如图5和图6所示，假设第一导电网丝1311、第二导电网丝1312、第三导电网丝1331、以及第四导电网丝1332的形状均为圆柱，圆柱的底面直径为d1；阳极13的总厚度为D；第一阳极131和第三阳极133的厚度均为2d1(即，平结打结处的厚度)；正方形第一阳极131和正方向第三阳极131的边长均为L；第一阴极11和第二阴极15的厚度均为d2，第一电活性聚合物12和第二电活性聚合物14的厚度均为d3；第一阳极131和第三阳极133的目数均为n。

由于一个驱动单元10的第二阴极15，复用作与其层叠设置、且相邻的驱动单元10的第一阴极11，并忽略未复用的一个第一阴极11或一个第二阴极15的厚度，可以得到驱动器的形变率为

Figure PCTCN2022136616-appb-000019
从表1可以看出，本申请提供的方案的驱动器理论最大形变率为26％，远大于相关技术的驱动器最大形变率11％。
另一个实施例中，如图7a-图8b所示，本申请实施例还提供一种驱动器，该驱动器包括驱动单元10，驱动单元10包括依次层叠设置的第一阴极21、第一电活性聚合物22、阳极23、第二电活性聚合物24、以及第二阴极25。
沿第一阴极21指向阳极23的方向，阳极23包括依次层叠设置、且电连接的第一阳极231和第二阳极232。第一阳极231包括间隔设置的多根第一导电网丝2311和间隔设置的多根第二导电网丝2312，多根第一导电网丝2311与多根第二导电网丝2312交结成网。第二阳极232包括间隔设置的多根第三导电网丝2321和间隔设置的多根第四导电网丝2322，多根第三导电网丝2321与多根第四导电网丝2322交结成网。
多个第一导电网丝2311在第一阴极21上的正投影，均与多根第三导电网丝2321在第一阴极21上的正投影错开设置。第二导电网丝2312在第一阴极21上的正投影，均与多根第四导电网丝2322在第一阴极21上的正投影错开设置。
此处，第一导电网丝2311的厚度与第二导电网丝2312的厚度可以相同，也可以不相同。第三导电网丝2321的厚度与第四导电网丝2322的厚度可以相同，也可以不相同。为了方便描述，下文均以第一导电网丝2311的厚度与第二导电网丝2312的厚度相同，第三导电网丝2321的厚度与第四导电网丝2322的厚度相同为例进行说明。
在一些可能实现的方式中，本申请实施例不对第一阳极231的多根第一导电网丝2311和多根第二导电网丝2312的交结方式，以及第二阳极232的多根第三导电网丝2321和多根第四导电网丝2322的交结方式进行限定。
可选的，如图7a和图7b所示，多根第一导电网丝2311和多根第二导电网丝2312可以采用一体化交结成网，多根第三导电网丝2321和多根第四导电网丝2322可以采用一体化交结成网。如图8a所示，多根第一导电网丝2311和多根第二导电网丝2312可以采用平结交结成网，多根第三导电网丝2321和多根第四导电网丝2322可以采用平结交结成网。当然，还可以采用其他方式交结成网，本申请实施例对此不作限定。例如，还可以采用斜结交结成网。
例如，如图7a和图7b所示，多根第一导电网丝2311和多根第二导电网丝2312一体化交结成网。第一导电网丝2311与第二导电网丝2312的交结处的厚度，与第一导电网丝2311的厚度和第二导电网丝2312的厚度均相同。
如图7a和图7b所示，多根第三导电网丝2321和多根第四导电网丝2322一体化交结成网。第三导电网丝2321与第四导电网丝2322的交结处的厚度，与第三导电网丝2321的厚度和第四导电网丝2322的厚度均相同。
在一些可能实现的方式中，在驱动器工作时，终端设备的控制电路，可以为第一阴极21、第二阴极25、以及阳极23供电，以满足驱动器工作时的充、放电条件。
此处，由于阳极23的第一阳极231和第二阳极232电连接，因此，在控制电路为阳极23充电的过程中，第一阳极231和第二阳极232均带正电荷。
本申请实施例提供的驱动单元10的工作原理可以为：在利用控制电路对第一阴极21、阳极23、第二阴极25充电时，第一阳极231的网丝带正电荷，第一电活性聚合物22在靠近第一阳极231侧带负电荷，因此，第一阳极231的网丝与第一电活性聚合物22相互吸引，第一电活性聚合物22沿着第一阳极231的网丝表面发生蠕变，并钻进第一阳极231的网孔中。同理，第二阳极232的网丝带正电荷，第二电活性聚合物24在靠近第二阳极232侧带负电荷，因此，第二阳极232的网丝与第二电活性聚合物24相互吸引，第二电活性聚合物24沿着第二阳极232的网丝表面发生蠕变，并钻进第二阳极232的网孔中。
在此基础上，对于一体化交结成网的多根第一导电网丝2311和多根第二导电网丝2312，以及一体化交结成网的多根第三导电网丝2321和多根第四导电网丝2322，由于多个第一导电网丝2311在第一阴极21上的正投影，均与多根第三导电网丝2321在第一阴极21上的正投影错开设置。第二导电网丝2312在第一阴极21上的正投影，均与多根第四导电网丝2322在第一阴极21上的正投影错开设置。因此，在第一阳极231的网孔与第二阳极232在第一阴极21的投影重合位置处，第二阳极232与第一电活性聚合物22相互吸引，第一电活性聚合物22不断向第二阳极232(即，第一阳极的网孔)处聚集，并钻进第一阳极231的网孔中。在第二阳极232的网孔与第一阳极231在第一阴极21的投影重合位置处，第一阳极231与第二电活性聚合物24相互吸引，第二电活性聚合物24不断向第一阳极231(即，第二阳极的网孔)处聚集，并钻进第一阳极231的网孔中。相较于相关技术的第一电活性聚合物22和第二电活性聚合物24在阳极23的网孔处互相排 斥，没有充分填满阳极23的网孔。本申请实施例可以利用第二阳极232吸引第一电活性聚合物22，促使第一电活性聚合物22钻进第一阳极231的网孔中；利用第一阳极231吸引第二电活性聚合物24，促使第二电活性聚合物24钻进第二阳极232的网孔中，提高第一电活性聚合物22和第二电活性聚合物24的实际形变率。
对于采用平结交结成网的多根第一导电网丝2311和多根第二导电网丝2312，以及采用平结交结成网的多根第三导电网丝2321和多根第四导电网丝2322，沿任一第一导电网丝2311指向与其相邻的第一导电网丝2311的方向，或者，沿任一第二导电网丝2312指向与其相邻的第二导电网丝2312的方向，第一导电网丝2311、第三导电网丝2321、第二导电网丝2312、以及第四导电网丝2322依次交错设置。
如图8b所示，在利用控制电路对第一阴极21、阳极23、第二阴极25充电时，第一电活性聚合物22和第二电活性聚合物24分别沿着附近的第一阳极231和第二阳极232表面蠕变，分别钻进第一阳极231和第二阳极232的网孔中。当第一电活性聚合物22钻进第三导电网丝2321和第四导电网丝2322之间的间隙中时，处于第三导电网丝2321和第四导电网丝2322之间的第一导电网丝2311和第二导电网丝2312均促进了第一电活性聚合物22进一步向第三导电网丝2321与第四导电网丝2322之间的网孔中聚集。同样的，当第二电活性聚合物24钻进第一导电网丝2311和第二导电网丝2312之间的间隙中时，处于第一导电网丝2311和第二导电网丝2312之间的第三导电网丝2321和第四导电网丝2322均促进了第二电活性聚合物24进一步向第一导电网丝2311与第二导电网丝2312之间的网孔中聚集。相较于相关技术的第一电活性聚合物22和第二电活性聚合物24在阳极23的网孔处互相排斥，没有充分填满阳极23的网孔。本申请实施例可以提高第一电活性聚合物22和第二电活性聚合物24的实际形变率。在一些可能实现的方式中，如图7b和图9所示，本申请实施例不对第一导电网丝2311与第三导电网丝2321的相对位置，以及第二导电网丝2312与第四导电网丝2322的相对位置进行限定，只要多个第一导电网丝2311在第一阴极21上的正投影，均与多根第三导电网丝2321在第一阴极21上的正投影错开设置；第二导电网丝2312在第一阴极21上的正投影，均与多根第四导电网丝2322在第一阴极21上的正投影错开设置即可。
可选的，如图7b所示，第一导电网丝2311的中心在第一阴极21上的正投影，与相邻两个第三导电网丝2321在第一阴极21上的正投影连线的中心重合；第二导电网丝2312的中心在第一阴极21上的正投影，与相邻两个第四导电网丝2322在第一阴极21上的正投影连线的中心重合。这样一来，在第一阳极231的网孔与第二阳极232在第一阴极21的投影重合位置处，可以利用第二阳极232最大程度吸引第一电活性聚合物22向第一阳极231的网孔处移动并聚集；在第二阳极232的网孔与第一阳极231在第一阴极21的投影重合位置处，可以利用第一阳极231最大程度吸引第二电活性聚合物24向第二阳极232的网孔处移动并聚集。
在一些可能实现的方式中，本申请实施例不对第一阴极21、第一电活性聚合物22、阳极23、第二电活性聚合物24、以及第二阴极25的材料进行限定，只要第一阴极21、阳极23、以及第二阴极23可以导电，第一电活性聚合物22和第二电活性聚合物24可以在电场作用下向阳极23聚集即可。例如，第一阴极21和第二阴极23的材料可以是铝 箔等。第一阳极231和第二阳极232的材料可以是不锈钢、铜镍合金等。第一电活性聚合物22和第二电活性聚合物24的材料可以是PVC凝胶。
PVC凝胶的制备过程可以是：将邻苯二甲酸二丁酯与四氢呋喃混合，并通过磁力搅拌器按照500rpm/min的转速搅拌混合液约1min，再缓慢添加PVC粉末到混合液中，其中，DBA与PVC粉末的质量比为4：1，DBA和PVC粉末总质量与THF总质量比为1：2.25，持续搅拌约24h。将混合液通过涂膜仪制备一定厚度(例如200μm)的薄膜，再通过刀模切割为适用于驱动单元10的尺寸(例如直径28mm圆形薄膜)。
在一些可能实现的方式中，本申请实施例不对第一阳极231和第二阳极232的目数进行限定，也不对阳极23各层的厚度进行限定。
可选的，第一阳极231和第二阳极232的目数范围可以是50～200目，即，第一阳极231和第二阳极232中，每一英寸*一英寸范围内，有50～200个网孔。此处，第一阳极231的厚度可以与第二阳极232的厚度相同，也可以不相同，本申请实施例对此不作限定。
可选的，第一阳极231和第二阳极232的厚度范围可以是50μm～300μm。例如，第一阳极231和第二阳极232的厚度可以为90μm。
在一些可能实现的方式中，第一阳极231与第二阳极232的形状和尺寸可以相同。或者，第一阳极231的形状与第二阳极232的形状相同，第一阳极231的尺寸与第二阳极232的尺寸不同。或者，第一阳极231的形状与第二阳极232的形状不同，第一阳极231的尺寸与第二阳极233的尺寸相同。
在一些可能实现的方式中，如图10所示，驱动单元10的数量为多个，沿第一阴极21指向阳极23的方向，多个驱动单元10层叠设置，从而提高驱动器形变位移量。由于在电场作用下，所有驱动单元10的第一阴极21和第二阴极25均带负电荷，因此，任一驱动单元10的第二阴极25，可以复用作与其层叠设置且相邻的驱动单元10的第一阴极21。
下面结合具体示例，计算本申请实施例提供的阳极23的网孔占有率，以及包括多个驱动单元10的驱动器的最大形变率。
如图10所示，假设第一导电网丝2311、第二导电网丝2312、第三导电网丝2321、以及第四导电网丝2322的形状均为圆柱，圆柱的底面直径为d1；阳极23的总厚度为D；第一阳极231和第二阳极232的厚度均为2d1(即，平结打结处的厚度)；正方形第一阳极231和正方向第一阳极231的边长均为L；第一阴极21和第二阴极25的厚度均为d2，第一电活性聚合物22和第二电活性聚合物24的厚度均为d3；第一阳极231和第二阳极232的目数均为n。
第一阳极231的第一导电网丝2311、第二导电网丝2312、以及网孔的总体积为2d1L 2，第二阳极232的第三导电网丝2321、第四导电网丝2322、以及网孔的总体积也为2d1L 2。

从表2可以看出，相较于相关技术的实际11％的形变率，本申请提供的方案的驱动器理论最大形变率可接近26％。从而可以更加有效地提高驱动器的压缩程度。
