Synthesis and Characterization of a Novel Aramid Fiber Liquid Crystalline Polymer

Abstract:

The-NH₂groups, as grafting initiators, are introduced to the surface of meta-aramid fibers by treating the fiber surface with dilute sodium hydroxide solution. A kind of new aramid fibers liquid crystalline polymer were synthesized by interfacial polymerization of mesogenic monomer DDBA, main-chain LCI containing sulfonate ionic monomer BY, sebacoyl dichloride and aramid fibers hydrolysed. The structure and properties of aramid fibers before and after modification were characterized by SEM, FTIR, and POM.
