Description

一种基于热调节的无氟环保防水透湿纳米纤维膜及其制备 方法
技术领域
本发明涉及静电纺丝技术领域和多功能防水透湿材料领域,尤其涉及一种基于热调节的无氟环保防水透湿纳米纤维膜及其制备方法。
背景技术
防水透湿材料是一种在可以抵御外部液态水浸透的同时,还能保证水蒸气传输的一种防护型材料,它在专业防护、户外运动、包装建筑等领域有着广泛的应用。静电纺丝法是近年来被广泛应用的一种简便、高效、适用范围广的防水透湿材料制备方式。该技术工艺简单易操作、适用范围广,且由它制备的纳米纤维膜孔径小、孔隙率高、比表面积大,是防水透湿功能的优良载体。当前的静电纺防水透湿纳米纤维膜大致可以分为疏水聚合物膜、掺杂剂改性膜和表面改性膜。疏水聚合物膜采用一种或多种疏水性聚合物为原料,通过溶液混纺成丝制备而成,这种方式简单高效,但受制于疏水聚合物本身疏水性能和种类的限制。掺杂剂改性膜是通过向聚合物溶液中添加少量的特定物质,以进一步提高材料的防水性或者赋予其新功能的作用,但该类膜仍然存在制备工艺复杂、多功能无法同步提升等瓶颈。表面改性膜则通过将材料利用加热、浸渍涂覆或气相沉积等后处理方式改善其疏水性,该类膜也常存在制备环节复杂、对技术要求较高等问题,且经浸渍涂覆处理的产物的耐久性同样令人担忧。于是,迫切需要一种简便可行的方法来制备高性能的防水透湿材料。
目前为止,氟类聚合物或含氟类疏水剂仍是防水透湿材料的主力军。虽然低表面能的氟类物质可以有效提升材料的防水性能,但随着人们对其毒性的深入研究,越来越多的人已经认识到了全氟和多氟物质的危害性。这些氟类物质对生物体的健康和生态环境的影响危害大、时间长,迫使科研学者寻求更安全环保的物质尽快取代它的应用。另外,人们对美好生活的追求也对防水透湿材料提出了更高的要求,功能单一的材料在这个需求多样化的生活中占据的市场地位被不断冲击,防水透湿材料的多功能化研究已是大势所趋;因此,设计一种基于热调节的无氟环保防水透湿纳米纤维膜及其制备方法是很有必要的。
发明内容
本发明解决的问题在于提供一种基于热调节的无氟环保防水透湿纳米纤维膜及其制备方法,针对目前防水透湿材料防水性较低、功能单一、制备工艺复杂或疏水剂含氟化等问题,提供一种制备高性能、多功能防水透湿材料的简便方法。利用一步静电纺丝技术,将疏水性相变材料脂肪酸添加到疏水型聚氨酯纺丝溶液中,利用脂肪酸中硬脂酸优异的相变能力和疏水效果,在大幅提高PU/SiPU/脂肪酸纳米纤维膜防水性的同时,还赋予了其优异的热调节能力,能够广泛应用于专业防护、产品包装、智能服装等领域。

一种基于热调节的无氟环保防水透湿纳米纤维膜的制备方法,包括以下步骤:
步骤S1:将PU、SiPU溶解在N-N二甲基乙酰胺和丙酮溶剂中,并向其中添加一定质量分数的脂肪酸颗粒,一同经磁力搅拌8-12h后得到均匀的静电纺丝溶液;脂肪酸的含量占溶质质量的0-50wt%;
步骤S2:将上一步所得的纺丝液置于静电纺丝装置上制备得到纳米纤维膜;静电纺丝装置主要由高压电源、喷射装置、接收装置三部分组成;纺丝参数设置如下:电压25.5±5kV,针头与接收辊之间的距离为22±5cm,喷灌速度为0.08±0.07mm/min,纺丝时间6±5h;
本发明的有益效果是:本发明制备的纳米纤维膜具有以下优点:
(1)无氟环保;本发明采用的PU/SiPU原料和脂肪酸疏水剂均不含氟,符合当下市场的环保趋势;
(2)防水透湿性能优异;本发明制备的PU/SiPU/硬脂酸纳米纤维膜的耐水压可达79kPa,透湿量为8.0kg m-2d-1
(3)兼具热调节性能;本发明制备的PU/SiPU/硬脂酸纳米纤维膜表现出优异的相变潜热;并通过改变脂肪酸的种类可以实现对纤维膜相变温度的改变。
