The True Liquid Crystal Phases of 2D Polymeric Carbon Nitride and Macroscopic Assembled Fibers

Abstract

Recently, fluids of fascinating nanomaterials have been reported to exhibit liquid crystalline (LC) phases and these mesophases have ignited considerable interest both in the fluid physics and in their cutting-edge applications. Graphitic carbon nitride (g-CN) which is one of 2D semiconducting polymer has gained a lot of attention over recent years due to particular interest in optoelectronic and catalytic applications. However, g-CN was studied on powder material which suffer from limited dispersibility, difficult recovery, and low surface accessibility. In this study, we report that controlled g-CN which has high-aspect ratio and expanded interlayer spacing can induce its true LC phase in concentrated sulfuric acid. By utilizing its LC phase, more importantly, we could fabricate g-CN fiber for the first time.
