Abstract
Polyurethane chain was successfully grafted onto carbon nanotubes, affording polyurethane-functionalized multiwalled carbon nanotubes (P-MWCNTs) with super-hydrophobic property, which shows improved abrasive resistance obviously and enhanced thermal conductivity for natural rubber (NR) vulcanizate. Under the optimized conditions, the akron abrasion loss of NR vulcanizate combined with 5 parts per hundred rubber (5 phr) P-MWCNTs is 0.9 cm3/1.61 km compared to 2.96 cm3/1.61 km of pristine NR vulcanizate. The thermal conductivity of NR vulcanizate combined with 5 phr P-MWCNTs has been improved by 40.3% compared to that of pristine NR vulcanizate. The decreased height of the maximum tan δ peak shows that P-MWCNTs can reduce the heat buildup and damping capability of NR/P-MWCNTs composites. The good dispersion of P-MWCNTs with a continuous network, particularly at high loading (5 phr) in the NR composites, was evidenced from transmission electron microscopy (TEM).
