- Abstract
Two different fibrous clays, halloysite nanotubes (HNTs) and organically modified attapulgite (OAT), were chosen to prepare poly( p-dioxanone) (PPDO)/clay nanocomposites by in-situ polymerization. The influence of surface character and geometric structure of the clays on the properties of the nanocomposites were investigated systematically concerning with their crystallization behaviors, thermal stabilities, rheological behaviors, and mechanical performances. The effect of clay content on the properties of the nanocomposites was also discussed, taking PPDO/HNTs nanocomposites for example. The results showed that HNTs was more effective in improving the crystallization rate, thermal stability as well as mechanical performance. In addition, the crystallization rate and rigidity of nanocomposites increased with increasing HNTs loading. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
