We developed photomobile polymer materials with interpenetrating polymer network (IPN) structures composed of crosslinked liquid-crystalline azobenzene polymer (PAzo) and poly(dimethylsiloxane) (PDMS). By introducing PDMS into a PAzo template network, IPN was formed without disturbing the alignment of mesogens in the PAzo network. The films showed macroscopic bending behavior upon irradiation with UV and visible light. Although the IPN film showed a phase separated structure, the bending speed was significantly enhanced compared with the pristine film of PAzo, thanks to the soft nature of PDMS. The present method of preparing IPNs can be a promising approach to combine PAzo with various polymers and enhance the mechanical and photoresponsive properties.

液晶偶氮苯聚合物和聚二甲基硅氧烷作为光移动材料的互穿聚合物网络

我们开发了具有互穿聚合物网络（IPN）结构的光敏聚合物材料，该结构由交联的液晶偶氮苯聚合物（PAzo）和聚二甲基硅氧烷（PDMS）组成。通过将PDMS引入PAzo模板网络，可以在不干扰PAzo网络中液晶元排列的情况下形成IPN。膜在用紫外线和可见光照射时表现出宏观的弯曲行为。尽管IPN膜显示出相分离的结构，但由于PDMS的柔软特性，与原始的PAzo膜相比，弯曲速度显着提高。目前制备IPN的方法可能是将PAzo与各种聚合物结合并增强机械和光响应特性的有前途的方法。
