Effect Of Different Filler Preparation Method On Properties Of Natural Rubber Palygorskite Nanocomposites

Recently, clay has been widely used as fillers to enhance properties in polymer nanocomposites at lower filler loading. However, the improvement of the properties depends on the ability of the clay to disperse in the polymer matrix. In this study, the mechanical, morphological and physical propertie...
