Silver nanowire/poly(dimethylsiloxane) (AgNW/PDMS)-based stretchable conductive films are widely studied due to their excellent comprehensive performances mainly derived from the great electrical conductivity of AgNWs together with the excellent mechanical and optical properties of PDMS. However, their further applications have been limited by two fatal shortcomings: the low surface energy of PDMS and poor elongation at break of AgNWs. Herein, an ultrathin PDMS-immobilized layer was prepared to construct a semi-embedded wrinkled AgNW network and overcome the limitations through spin-coating the pre-polymerized PDMS solution. As a result, the as-prepared transparent stretchable AgNW/PDMS composite films with different AgNW loadings demonstrate great transmittance, conductivity, tensile stability under 40% and 60% strains, and adhesion of AgNWs on the PDMS substrate. With a further increase of AgNW loadings, reflective stretchable conductive films were obtained and they showed a much lower sheet resistance (∼0.2 Ω sq⁻¹) and good tensile stability under 70% strain. Based on these stretchable conductive films, stretchable electrothermal chromatic films and electrothermal actuators were fabricated to demonstrate their multifunctional applications.

预聚合辅助制造超薄固定层，以实现用于智能电热彩色显示器和致动器的半嵌入式起皱AgNW网络

基于银纳米线/聚二甲基硅氧烷（AgNW / PDMS）的可拉伸导电膜由于其优异的综合性能而受到广泛研究，这主要源于AgNW的高导电性以及PDMS的优异的机械和光学性能。然而，它们的进一步应用受到两个致命缺陷的局限：PDMS的低表面能和AgNW的断裂伸长率差。本文中，制备了超薄PDMS固定层，以构建半嵌入式起皱的AgNW网络，并通过旋涂预聚合的PDMS溶液克服了局限性。结果，制备的具有不同AgNW负载量的透明可拉伸AgNW / PDMS复合膜在40％和60％应变下显示出极高的透射率，导电性，拉伸稳定性，AgNW在PDMS基材上的附着力和附着力。随着AgNW负载的进一步增加，获得了反射型可拉伸导电膜，并且显示出低得多的薄层电阻（〜0.2Ωsq^-1）和在70％应变下的良好拉伸稳定性。基于这些可拉伸的导电膜，制备了可拉伸的电热彩色膜和电热致动器，以展示其多功能应用。
