Abstract

In this work, the effect of oxygen plasma treatment of nano-scaled silica on the mechanical interfacial properties and thermal stabilities of the silica/rubber composites was investigated. The surface properties of the silica were studied in X-ray photoelectron spectroscopy (XPS) and contact angles. And, their mechanical interfacial properties and thermal stabilities of the composites were characterized by tearing energy ($G_{IIIC}$) and thermogravimetric analysis (TGA), respectively. As a result, it was found that the introduction rate of oxygen-containing polar functional groups onto the silica surfaces was increased by increasing the plasma treatment time, resulting in improving the tearing energy. Also, the thermal stabilities of the composites were increased by increasing the treatment time. These results could be explained that the polar rubber, such as acrylonitrile butadiene rubber (NBR), showed relatively a high degree of interaction with oxygen-containing functional groups of the silica surfaces in a compounding system.
