| Abstract: | The attapulgite was dispersed in the water by stirring and ultrasonic vibration, observing the shape of the attapulgite with TEM after the process. Then it was treated with a silane coupling agent KH570. The surface structure of the attapulgite was characterized by means of X-ray photoelectron spectroscopy(XPS). The results shows that the silane coupling agent has been grafted to the nano-fibred crystal of attapulgite. Then the treated attapulgite was blended with polypropylene(PP) via melt compounding to prepare PP/attapulgite nanocomposites. The effect of attapulgite on crystalline behavior and mechanical properties was investigated. It shows the attapulgite can increase the mechanical properties of the composites to a certain extent and attributes to the crystalline of PP. |
