Liquid Crystallinity of p-Aramid/Multi-walled Carbon Nanotube Composites

Abstract

A systematic study regarding the liquid crystallinity of p-Aramid and MWCNTs composite at various p-Aramid and MWCNTs concentrations in sulphuric acid was investigated and optimized by solution viscosity measurement and opalescence observation. We observed a merged liquid crystalline phase consisting of both p-Aramid and MWCNTs, and we believe this is the first study to report this combined liquid crystalline phase in one suspension. In addition to providing fundamental insights, we envision this study could be useful to those developing a strong, light, and high-performance polymeric composite fibers.
