A Chitosan/Poly(vinyl alcohol) Nanocomposite Film Reinforced with Natural Halloysite Nanotubes

摘要

Biodegradable polymer/clay nanocomposites have attracted tremendous attentions because of their excellent properties and ecofriendly advantages. In this article, a series of nanocomposite films were prepared by introducing of halloysite nanotubes (HTs) into chito-san (CS)/poly(vinyl alcohol) (PVA) matrix using the solution casting method, and the effect of HT as nanofillers on the properties of polymer/HT nanocomposites was explored. The results indicated that the tensile strength of CS/PVA/HT3 and elongation at break of CS/PVA/HT2 sharply increased by 39.72% and 26.14% in comparison with the pure CS/PVA film, respectively. The water resistance and thermal stability of polymer/HT nanocomposites were also improved compared with the pure CS/PVA film, but the optical property of the nanocomposite films was not affected by introducing HT into the CS/PVA matrix.
