Abstract
SummaryThis paper reports the effect of surface modification on the mechanical and morphological properties of palygorskite (PAL) filled natural rubber (NR) nanocomposite. NR/PAL nanocomposites were prepared by co‐coagulating rubber latex with clay suspension and after that, compounded with SMR 20 using melt mixing method. The aim is to investigate the efficiency of surface modification via cation exchange treatment on treated NR/PAL nanocomposite properties as compared to untreated NR/PAL nanocomposite. The organo‐modified palygorskite was characterized by fourier transform infrared spectroscopy (FTIR) and X‐Ray diffraction (XRD). The NR/PAL composites were subjected to cure characteristic, tensile, tear, hardness and scanning electron microscopy (SEM) with energy dispersive x‐ray (EDX) testing. The treated NR/PAL nanocomposite showed higher mechanical properties compared to untreated samples. FTIR revealed the functional group from 1‐dodecylammonium chloride react with PAL. The dispersion of PAL in the rubber matrix, can be seen clearly using XRD and SEM/EDX.
