Abstract
Polycarbonate (PC)/liquid crystalline polymer (LCP)/Multiwall carbon nanotube (MWNTs) nanocomposites containing as-received and modified (COOH-MWNT) carbon nanotubes were prepared through melt process in extruder and then compression molded. The chemical modification of MWCNT enhances the compatibility as well as miscibility between Polycarbonate and LCP in the concerned composites. Incorporation of functionalized MWCNTs improves the thermal, mechanical dynamic mechanical and electrical properties of the composites. Storage modulus and glass transition temperature increases in a remarkable fashion due to the enhanced interfacial adhesion between the PC/LCP/COOH-MWCNT. Field emission microscopy (FESEM) and HRTEM exhibit LCP fibrillation and fine dispersion of COOH-MWCNT throughout the matrix highlighting the miscibility between LCP and PC matrix.
