Abstract
An optically active poly(hydrazide-imide) (PHI) containing L-lysine was prepared by interfacial polycondensation. The corresponding polymeric nanocomposites have been prepared using multi-walled carbon nanotube (MWCNT) through sonication. Crystallization was studied by DSC (Differential scanning calorimetry) technique. Incorporation of nanotubes into the polymeric matrix improved the mechanical properties of the PHIMWCNT nanocomposites. Electrical percolation was observed at more than 0.5 wt% of MWCNT in the PHI matrix. All studies revealed that ultrasound assisted method causes effective dispersion of MWCNTs in the PHI matrix. The polymeric nanocomposites were characterized by FT-IR, XRD, TEM, DSC, mechanical tests, and the DC electrical conductivity measurements.
Keywords: Conductivity, crystallization, MWCNT, optically active, poly (hydrazide-imide), ultrasonic.
