제목 Microstructural and Property Characterization of Ternary Nanocomposites Based on Thermotropic Liquid Crystal Polyester/Polycarbonate Blend and Carbon Nanotube
초록 Thermotropic liquid crystal polyester (TLCP) has recently attracted great attention as high-performance engineering plastics owing to its excellent mechanical strength, heat resistance, and shape stability. Polycarbonate (PC) is a thermoplastic and amorphous polymer with high thermal stability and impact strength. In this study, to attain multifunctional and high-performance thermoplastic-based composites for advanced applications, a series of ternary nanocomposites based on TLCP/PC blend and multiwalled carbon nanotube (MWCNT) are fabricated via efficient masterbatch-based melt-compounding. The morphological and microstructural features of the ternary nanocomposites are characterized using SEM, FT-IR, and XRD. The thermal transition, thermal stability, rheological, mechanical, and electrical properties of the ternary nanocomposites are investigated using DSC, TGA, rheometer, DMA, and electrometer, respectively.
