	Abstract

Novel antistatic agents containing metal salt were used to prepare polyurethane foam (PUF) in this study. The effects of different conditions such as amount of antistatic agent, type and ratio of metal salt, temperature, relative humidity and time, on the surface resistivity were studied. Typically, the research of replacement of silver metal salt with tin metal salt has been conducted. Antistatic property of these composites illustrates that AgIO₃ metal salt replaced by two-thirds amount of SnCl₄ also shows excellent conductivity. Structure and other properties of these conductive PUF were examined by FTIR, DSC, and TGA. Moreover, the antistatic mechanism of these agents was put up. It was proposed that the metal salt in the antistatic agent might develop a conducting road. This can increase conductivity of the polymeric materials and decrease the corresponding surface resistivity.
