The attapulgite(AT) were dispersed into polyvinyl alcohol(PVA)-chitosan(CS) matrix to get polyvinyl alcohol-chitosan/attapulgite composites through blending method with different compositions. Effects of amount of attapulgite(compare to total mass of polyvinyl alcohol and chitosan) on the properties of polyvinyl alcohol-chitosan/attapulgite composites were investigated. The mechanical properties showed that when the dosage of attapulgite were 5%,the mechanical properties of the polyvinyl alcohol-chitosan/at...
