Problems solved by technology

According to literature reports, the preparation of thermotropic liquid crystal copolyester / graphene composites adopts the process of in-situ solution polymerization, which needs to consume a large amount of solvent during the preparation process, which is not conducive to environmental protection, and is prepared by in-situ solution polymerization. The thermotropic liquid crystal copolyester / graphene composite material has poor mechanical properties and cannot meet the requirements of practical applications;
