Abstract: Removing H2O from attapulgite by heat, treating attapulgite with organic reagents, testing moistening capacity of samples with styrene, we prepared attapulgite/Polystyrene Nanocomposite with the samples which are well in moisteming capacity.In this paper, we discuss the factors that affect the result of organic treatment of attapulgite, including the temperature of heat treatment, the kind and content of organic reagent, the time of organic treatment. We also discuss the relationship between the ratio of attapulgite in material and the mechanics performance. The work processes are probably factors that affect the structure of attapulgite.
