Kinetic of thermal degradation and thermal stability of natural rubber filled with titanium dioxide nanoparticles

Abstract

This article deals with the kinetic of thermal degradation and thermal stability of natural rubber (NR) filled with titanium dioxide (TiO 2 ) nanoparticles. Incorporation of TiO 2 nanoparticles was done through a latex mixing method. This is to ensure the homogeneity of TiO 2 nanoparticles throughout the NR matrix. Adding TiO 2 nanoparticles results in shifting the decomposition temperature and char residue irrespective of the loadings of TiO 2 nanoparticles. This is confirmed by the calculated kinetic parameters of the composites, indicating that higher energy is required to decompose the NR chains. Based on this analysis, a schematic model for thermal stability of TiO 2 nanoparticles filled NR composites is proposed. POLYM. COMPOS., 40:3149–3155, 2019. © 2018 Society of Plastics Engineers
