将乙炔黑(AB)作为导电填料引入Ecoflex®00-30弹性体中,制备了一种超弹性渗流导电复合材料。根据渗流理论,电导率可以提高几个数量级,还可以通过改变AB体积比来调整杨氏模数。AB-Ecoflex复合材料的电导率高达6.4 S·m−1,在200%应变下循环100次后仍保持稳定。这种复合材料具有高导电性、可伸缩性和稳定性,显示出作为可穿戴应变传感器检测人体运动和人机界面应用的巨大潜力。
A hyperelastic percolative conductive composite is proposed with acetylene black (AB) as conductive filler introduced into Ecoflex® 00-30 elastomer matrix. The conductivity could be enhanced by several orders according to percolation theory and the Young’s modulus could also be tailored by modifying AB volume ratio. The AB-Ecoflex composite exhibits electric conductivity high as 6.4 S·m−1and remains stable after 100 cycles at 200% strain. This composite with high conductivity, stretchability and stability shows high potential as a competitive candidate for wearable strain sensors to detect human body motions and for human-machine interface application.
