合成了两种不同偶氮甲苯浓度的新型反应性线性液晶聚合物，并通过溶液和熔融加工方法将其加工成薄膜和纤维。然后，在所获得的单域纤维和多域膜的LLCPs很容易与双官能伯胺交联。所得的交联液晶聚合物（CLCPs）在室温下分别在445和530 nm可见光下发生可逆的光致弯曲和不弯曲行为。后交联法是一种简单易行的方法，可以用传统的熔融法和溶液法制备出不同形状的CLCP薄膜和纤维。
Two types of novel reactive linear liquid crystal polymers (LLCPs) with different azotolene concentrations have been synthesized and processed into films and fibers by solution and melting processing methods. Then, the LLCPs in the obtained monodomain fiber and polydomain film were easily cross-linked with difunctional primary amines. The resulted cross-linked liquid crystal polymers (CLCPs) underwent reversible photoinduced bending and unbending behaviors in response to 445 and 530 nm visible light at room temperature, respectively. The post-cross-linking method provides a facile way to prepare the CLCP films and fibers with different shapes from LLCPs, which can be processed by traditional melting and solution methods.
