摘要: Natural rubber (NR)/multi-walled carbon nanotube (MWCNTs) composites were prepared by combining self-assembly and latex compounding techniques. The acid-treated MWCNTs (H(2)SO(4): HNO(3)=3:1, volume ratio) were self-assembled with poly (diallyldimethylammonium chloride) (PDDA) through electrostatic adhesion. In the second assembling, NR/MWCNTs composites were developed by mixing MWCNTs/PDDA solution with NR latex. The results show that MWCNTs arc homogenously distributed throughout the NR matrix as single tube and present a great interfacial adhesion with NR phase when MWCNTs contents are less than 3 wt%. Moreover, the addition of the MWCNTs brings about the remarkable enhancement in tensile strength and crosslink density compared with the NR host, and the data peak at 2 wt% MWCNTs loadings. When more MWCNTs are loaded, aggregations of MWCNTs are gradually generated, and the tensile strength and crosslink both decrease to a certain extent.
