Effect of Attapulgite Modification on Properties of Polypropylene Nanocomposites

摘要：

　　Polypropylene nanocomposites were prepared by means of melt mixing using attapulgite as inorganic components.The relation between surface free energy and mechanical properties of polypropylene nanocomposites and elasticized mechanism analysis of modified attapulgite nanofibers were mainly studied.The results showed that the modulus, fracture strength, fracture extensibility, tensile strength, yield strength, bend strength, flexural modulus and dynamic ductility properties of nanocomposites all enhanced obviously after modified attapulgite nanofibers were filled up.Surface free energy of attapulgite nanofibers and impact toughness properties of nanocomposites were in approximate inversely-proportion quadratic function relationship, which could provide a new way of thinking in the field of nanocomposites research.
