Nano Alumina as Reinforcement in Natural Rubber Composites

Teena Thomas, Ayswarya E. P. and Eby Thomas Thachil

Nano alumina (Al2O3) was prepared by gel combustion method. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the nano alumina. The results show that the prepared alumina was in nano meter range. It was added as reinforcing filler in natural rubber. Mechanical property improvements were achieved by the addition of low amounts of nano alumina along with maleic anhydride as compatabilizer.
