Also, this method possesses some other advantages, such as low energy cost and homogeneous dispersion of silica in NR matrix. Latex compounding, therefore, can reduce harmful situation mentioned above, and be more eco-friendly and low-polluted processing. However, in order to obtain homogeneous dispersion of polar nanosilica in apolar natural rubber latex, surface modification of nanoparticles is required. There has been numerous numbers of publications reported in this field, such as chemical coating using coupling agents [18–21] and physical coating using detergents [22] whereas rare researches are referred to the surface functionalization of nanosilica and dispersing process in natural rubber latex. In this paper, a novel method to prepare NR/SiO2 nanocomposite will be reported.
