Enhanced wear resistance and micro-hardness of polystyrene nanocomposites by carbon nanotubes

Polystyrene-carbon nanotubes (PS-CNTs) nanocomposites with 0–4.0 wt.% content have been prepared successfully by means of in situ polymerization process. The microhardness of PS-CNTs nanocomposites was measured. It was found that CNTs effectively increased the microhardness of the nanocomposites. The tribological behaviors of the nanocomposites were investigated by a friction and wear tester under dry conditions. Comparing with pure PS, PS-CNTs...
