Facile and Green Method for Fabrication of Polystyrene/Multi-Walled Carbon Nanotube Composites with Covalent Functionalization

Polystyrene (PS) nanoparticles/multi-walled carbon nanotube (MWCNT) composites were prepared by emulsion polymerization in the presence of styryl-modified MWCNTs. The Fourier transform infrared spectroscopy and scanning electron microscope confirm the effectiveness of functionalization of MWCNTs and the strong interactions between MWCNTs and PS nanoparticles. The results of transmission electron microscopes further support the covalent functionalization process.
