Properties of transparent PMMA/PEG/MWNTs nanocomposites prepared by in situ polymerizaon

摘要

PMMA (poly(methyl methacrylate)) / PEG (poly(ethylene glycol)) / MWNTs (Multi-walled Carbon Nanotubes) (PMMA/PEG/MWNTs) nanocomposites were prepared by in situ polymerization. The effect of different weight percent loadings of MWNTs on the morphological, transmittances and thermal properties of the nanocomposites,had been investigated. Scanning electron Microscopy (SEM) showed that MWNTs were dispersed uniformly based on the interaction of hydrogen bonds between MWNTs and PEG. When MWNTs were added, the dynamic moduli and thermal stability of PMMA/PEG/MWNTs nanocomposites improved with increasing MWNTs content.
