Polycarbosilane derived beta silicon carbide coated multi wall carbon nanotubes (MWCNTs) reinforced polyetherimide (PEI) nano-composites (with 0.1 to 0.3 phr coated MWCNTs reinforcements) have been fabricated by a sigma high temperature internal mixer followed by compression. Scanning electron microscopy (SEM) shows uniform and homogeneous dispersion of the coated MWCNTs in polyetherimide matrix, due to interfacial adhesion between the coated MWCNTs and the PEI matrix. Increasing mechanical properties of coated MWCNT/PEI nanocomposites with increasing amounts of coated MWCNTs in their compositions, confirm reinforcing effect of MWCNTs in PEI matrix in coated MWCNT/PEI nanocomposites. Thermo gravimetric analysis shows that the thermal stability of coated MWCNT/PEI nanocomposites is same as of PEI. 9 Refs.
