Influence of layered silicates on properties polytetrafluoroethylene
INTRODUCTION Using layered silicates as fillers holds promise in structural modification of polymers. The interest in silicates as effective modifiers of the polymer matrix is attributed to their capability of forming spatially continuous structures in the composite owing to the specific structural arrangement of minerals. The modifying ability of layered silicates can be fully used through intercalating polymer macromolecules in the interlayer spaces (galleries) of the filler particles. Further exfoliation of the fillers into singular layers～1nm thick possibly results in nanocomposites having properties exceeding those of the starting polymer. Improvement of the compatibility of the composite component and provision of interaction are the main problems in nanocomposite development. Mechanical activation of silicates under optimal treatment conditions is the simplest, and fairly productive, solution.
