摘要

In this study, compatibilizing ability of silicone carbide modified multiwalled carbon nanotube (MWCNT) and polyphosphazene for the incompatible polyetherimide/liquid crystalline polymer (LCP) blend was investigated in detail. From rheological study, it was evident that the viscosities of binary and ternary blends were lower than those of the neat polymers, which signifying the great ability of LCP as a processing aid. Field emission scanning electron microscopic analysis revealed that the addition of polyphosphazene and modified MWCNT, together, reduced the average domain size of LCP and improved the filler-matrix adhesion. Measurement of surface energy from contact angle measurement also point towards the improved interfacial interaction, in presence of compatibilizers.
