氧化石墨烯/液晶网络复合膜的响应性能及仿生设计OACSTPCD

Liquid crystal network(LCNs)is a liquid crystal polymer moderately crosslinked,and has the elasticity of polymer and the anisotropy of liquid crystal,including multi-stimulus response,reversible drive and programmable shape deformation properties.Therefore,it has good field responsiveness,molecular synergy and elasticity.Graphene oxide film has excellent photothermal conversion performance,and light has excellent properties such as environmental protection and remote controllability,so photodeformable graphene oxide/liquid crystal networks(GO-LCNs)have gradually become the focus of research.It can produce flexible robots,bionic photothermal actuators and other advanced devices,and has a good development prospect.In this paper,we prepared graphene oxide films on two thickness of liquid crystal network to obtain the composite film,and tested the response performance under heating stage or infrared light.The results provide an experimental basis for the application design of the composite membrane,and on this basis,the bionic device of GO-LCNs composite membrane is designed.
