Abstract
Abstract Natural rubber (NR)/montmorillonite (MMT) nanocomposites compatibilized with epoxidized natural rubber (ENR) were produced by latex compounding method. The effects of ENR as a compatibilizer on NR/MMT nanocomposites were investigated. The addition of ENR brought intercalation or exfoliation of the clay, which improved the clay dispersion in the rubber matrix, as characterized by X-ray diffraction (XRD) and transmission electronic microscopy (TEM). The interfacial interaction of ENR with MMT was investigated by Fourier transform infrared spectroscopy (FTIR). The vulcanization was hindered by the incorporation of ENR, while the mechanical performances, thermal stability and ageing resistance were improved. The glass transition temperature and storage modulus increased with ENR loading, which was corroborated by dynamic mechanical analysis (DMA).
