STUDY ON PROPERTIES AND PREPARATION OF POLYAMIDE 66/ATTAPULGITE NANOCOMPOSITES

Lai Shiquan~(1,2),Yue Li~2,Li Tongsheng~1(1.Department of Polymer Science,Fudan University,Shanghai 200433,China;2.Institute of Chemical Engineering,Anshan University of Science and Technology,Anshan 114004,China)  
Polyamide 66/attapulgite nanocomposite was prepared by mixing attapulgite particles which were purified,treated by sodium chloride and organized beforehand with polyamide 66 by using two-screw mixer.The microstructure of attapulgite in polyamide 66 matrix was studied by transmission electron microscope and scanning electron microscope,and the mechanical and thermal porperties of the composite were also tested.The results showed that diameter of attapulgite particles in polyamide matrix was less than 100 nm.Moreover,tensile strength and thermal properties of the polyamide 66 nanocomposites were improved to a certain degree by filling appropriate content of attapulgite particles to polyamide polymer.
