Crystal polymers
WebAug 14, 2024 · Crosslinked liquid crystalline polymers (CLCPs) are a type of promising smart materials that possess both the ordered alignment of liquid crystals (LCs) and the elasticity of polymer networks. The anisotropic photodeformation of CLCPs takes place when mesogens experience order to disorder change in response to light. WebLCPs – liquid crystal polymers – are thermoplastic resins which exhibit unique properties. These materials have many unique and desirable traits including exceptional mechanical strength, heat tolerance for autoclaving, and chemical inertness. Thus, these materials have found favor in many high performance applications from automotive ...
