可拉伸的透明复合材料已被合成的银纳米线（AgNW）网络嵌入在交联的聚（丙烯酸酯）矩阵的表面层。AgNW和交联聚合物基质的互穿网络导致高表面电导率、高透明度和橡胶弹性。聚合物链上羧酸基团的存在增强了AgNW与聚合物基体之间的键合，并进一步增加了复合材料的拉伸性能。复合电极的薄层电阻在50%应变下仅增加2.3倍。重复拉伸至50%应变和松弛仅导致600次循环后薄层电阻的小幅增加。研究了复合材料在可逆拉伸和弛豫过程中的形态，以阐明电导率的变化。
Stretchable transparent composites have been synthesized consisting of a silver nanowire (AgNW) network embedded in the surface layer of a crosslinked poly(acrylate) matrix. The interpenetrating networks of AgNWs and the crosslinked polymer matrix lead to high surface conductivity, high transparency, and rubbery elasticity. The presence of carboxylic acid groups on the polymer chains enhances the bonding between AgNWs and the polymer matrix, and further increases the stretchability of the composites. The sheet resistance of the composite electrode increases by only 2.3 times at 50% strain. Repeated stretching to 50% strain and relaxation only causes a small increase of the sheet resistance after 600 cycles. The morphology of the composites during reversible stretching and relaxation has been investigated to expound the conductivity changes.
