本发明提供了一种弹性织物/导电膜复合材料的制备方法,包括以下步骤:
步骤1:将聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)水相分散液、表面活性剂、粘合剂和导电增强剂进行混合,均质化后得到导电基体分散液;
步骤2:将弹性织物浸泡在导电基体分散液中,然后挤压移除弹性织物上过量的溶液,干燥后得到弹性织物/导电膜复合材料。
本发明粘合剂的加入,有利于导电粒子聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)固定在弹性织物基体上;表面活性剂和导电增强剂来调整和改善聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)导电粒子在分散液中的均一性和导电性,从而可均匀涂覆到弹性织物基体表面甚至内部,避免在拉伸过程中因弹性织物结构转变导致导电基体的大距离位移,使得弹性织物/导电膜复合材料的导电性保持稳定;另外,本发明导电基体是一种均匀的分散液,对弹性织物的浸渍效果好。本发明提供的弹性织物/导电膜复合材料的制备方法简单,易操作,制备成本低。
本发明步骤1中,优选使用注射器将聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)水相分散液、表面活性剂和导电增强剂剂进行混合,静置;混合优选采用磁力搅拌器在400r/min速度下搅拌15mins,静置除去搅拌过程中产生的气泡,静置的时间优选为12h;
表面活性剂选自十二烷基苯磺酸或十二烷基硫酸钠,优选为十二烷基苯磺酸,纯度为95%;
导电增强剂选自二甲基亚砜或乙二醇,优选为二甲基亚砜,纯度为99.7%;

聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)分散液与粘合剂的质量比为(90~95):(0~5),优选为95:2。当粘合剂的量减少时,聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)的量成比例增加,使得粘度相应降低。
本发明步骤2之前,还包括:对弹性织物进行预处理;
预处理具体为:将弹性织物用蒸馏水洗涤,再放入乙醇溶液中,在室温下超声处理,使得弹性织物进行彻底清洁,然后将超声处理后的弹性织物进行干燥,得到洁净的弹性织物;
弹性织物优选剪成长度为70毫米,宽度为25毫米的长方形布片;超声处理的温度优选为室温,时间优选为15mins,功率优选为100W。
本发明对弹性织物进行预处理可明显增加织物与导电层之间的结合力。
本发明步骤2中,将弹性织物浸泡在导电基体分散液中,使得导电基体分散液浸透弹性织物;
弹性织物选自棉布、莫代尔或互锁结构的锦棉织物,优选为互锁结构的锦棉织物。采用互锁的织物结构,经过导电聚合物的复合,可以制备成径向和纬向不同性能的传感器,可满足多方向使用。

所述浸泡的时间为5~15mins,优选为15mins;
接着,优选采用浸轧机挤压除去弹性织物上多余的溶液,浸轧1~10次后,干燥后得到弹性织物/导电膜复合材料;浸轧过多对织物造成损伤织物的损伤,本发明浸轧1~10次使得织物达到最佳的导电性,且不会造成织物的损伤。
干燥的温度优选为80℃,时间优选为30mins。
本发明使用浸轧工艺进一步使得导电基体均匀公布在弹性织物内纤维的表面。

本发明还提供了一种可拉伸柔性复合织物基传感器,由以下步骤制得:
将上述弹性织物/导电膜复合材料的两端连接导线,并在连接点处刷涂银浆,然后采用高弹性聚合物对弹性织物/导电膜复合材料进行热压密封,得到可拉伸柔性复合织物基传感器。
本发明中,将所述可拉伸柔性复合织物基传感器进行在应用条件下的预拉伸处理,从而去除织物微观瑕疵或织物纤维间的导电粒子对重复拉伸过程中导电性能的影响作用。
本发明可拉伸柔性复合织物基传感器的电阻为300-50000欧姆,导电性合适。
本发明中,为了获得良好的电接触,优选在导电膜复合材料两端通过银浆连接电极,电极优选为导电纱线。
本发明在不使用粘合剂的情况下,仅采用高弹性聚合物膜对导电膜复合材料进行双面热压,既避免了高分子柔性器件受环境湿度影响的问题,还保持良好柔软性和顺从,使得该传感器性能稳定。而且,该可拉伸柔性复合织物基传感器具有良好强度、柔性和导电性,形状可客户化定制。该制备方法简单,易操作,制备成本低。可拉伸柔性复合织物基传感器可实时检测物体体积及形态变化,适合于可穿戴装置(服装、鞋等)的各种应用领域,特别适用于动作频率,肢体状态或运动幅度等人体变化监测,以对人体姿势,步态,运动效能,健康状态等进行监测和分析。
本发明中,高弹性聚合物薄膜为热塑性聚氨酯薄膜;
热塑性聚氨酯薄膜厚度太薄会导致膜不耐刮,容易在受到磨损后破裂。厚度太厚会导致弹性变差。因此,本发明热塑性聚氨酯薄膜的厚度为0.01~0.05mm,优选为0.02mm,硬度优选为85A;
热压密封的时间为20~40s,温度为140~150℃,压力为6MPa。

首先使用注射器将95份聚(3,4-乙烯基二氧噻吩):聚(苯乙烯磺酸盐)分散液(固含量1.3mg/ml),1份十二烷基苯磺酸(纯度为95wt%)和5份二甲基亚砜(纯度为99.7wt%)混合,用磁力搅拌器在400r/min速度下搅拌15mins,静置12h。然后,使用注射器缓慢滴加2份水性聚氨酯粘合剂(固含量为40%)溶液,同时用磁力搅拌器在1000r/min下搅拌上述混合物,持续搅拌30mins进行均质化以获得均匀的糊状导电基体分散液,再静置12小时待用。
实施例2
本实施例进行弹性织物基底的预处理
将弹性织物剪成长度为70毫米,宽度为25毫米的长方形布片,用蒸馏水洗涤三次后放入盛有60毫升乙醇的100毫升容积的烧杯中,室温条件下超声(超声功率为100W)处理10mins,使弹性织物彻底清洁。然后将上述超声处理后的样品在烘箱中于80度下干燥30mins,以获得洁净的预处理的弹性织物基底。
实施例3
本实施例为弹性织物/导电膜复合材料的制备(请参阅图1)
移取实施例1制得的导电基体分散液20毫升置于100毫升的烧杯中,然后加入实施例2中所获得的经过预处理的弹性织物基底(尺寸为70.0毫米×25.0毫米),其中导电分散液与弹性织物基底的质量比为5:1。室温条件下用玻璃棒搅拌和浸泡15mins,使导电基体充分浸透织物基底,然后采用浸轧机将多余的导电基体溶液从弹性织物基底通过浸轧机挤压移除(浸轧机压力值设定为2kg/cm2),三次浸轧后,将样品在烘箱中于80℃下干燥30mins,得到导电膜复合材料。将制得的弹性织物/导电复合材料从烘箱中拿出,直接于样品袋中密封保存。利用微观扫描电镜对实施例3制得的弹性织物/导电膜复合材料进行检测,得到其扫描电镜照片如图2所示。由图2可看到弹性织物/导电膜复合材料的表面形态和导电聚合物基体的膜状结构以及导电聚合物基体均匀涂覆于织物上。
实施例4
本实施例为可拉伸柔性复合织物基传感器的制备(请参阅图1)
将实施例3制得的弹性织物/导电膜复合材料从密封袋中取出,于烘箱80度下干燥60mins,然后在导电膜复合材料的两端连接导线并在连接点处涂刷银浆增强导电性,然后取厚为0.02毫米的热塑性聚氨酯薄膜,通过热压密封实施例3制备的弹性织物/导电膜复合材料,热压时间为25秒,压力为6兆帕,热压温度140摄氏度。热压后得到的包覆的弹性织物/导电膜复合材料即为可拉伸柔性复合织物基传感器。将所述可拉伸柔性复合织物基传感器进行在应用条件下的预拉过程,从而去除织物微观瑕疵或织物纤维间的导电粒子对重复拉伸过程中导电性能的影响作用。
经测定,本实施例制备的所选尺寸的可拉伸柔性复合织物基传感器样品的长度方向的电阻初始值约为1100欧姆(长度方向的两端测试),预拉后电阻初始值约为5700欧姆,当拉伸长度为50%时电阻约为7800欧姆,拉伸前后导电性变化合适。
图3为本发明实施例4制得的可拉伸柔性复合织物基传感器的结构示意图。从图3可以看到导电膜复合材料包覆在热塑性聚氨酯薄膜内。
图4为本发明实施例4中制得的可拉伸柔性复合织物基传感器的拉伸形变与电信号关系图。结果表明该实施例制备的可拉伸柔性复合织物基传感器拉伸率和电信号在给定的小拉伸范围内呈增长变化,可用于测量人体结构尺寸的变化。而在大拉伸范围内可精确测量动作频率和运动幅度的变化。
图5为本发明实施例4中制得的可拉伸柔性复合织物基传感器预拉伸后的重复稳定性测试图。500次拉伸试验结果表明该可拉伸柔性复合织物基传感器的电信号变化范围稳定,可用于信号监测。
图6为本发明实施例4制得的可拉伸柔性复合织物基传感器的湿度影响作用图。所用方法为将相同大小的样品置於不同湿度条件下等待20mins后所测得的电阻比较图。从图6可以看到弹性织物/导电复合材料包覆在密封的热塑性聚氨酯薄膜内可避免湿度的影响作用。
