Polymer nanocomposites based on organic-inorganic clay minerals have attracted a great deal of attention in both scientific and industrial areas because they often exhibit improved mechanical, thermal, and flammability and barrier properties by dispersing nano-sized clay mineral particles throughout a polymer matrix. Halloysite nanotube (HNT) is a type of naturally occurring clay mineral with predominantly hollow tubular structure in the submicrometer range. HNT is attracting interest as a new class of nanofiller to reinforce polymers due to its cost effectiveness, natural availability, and biocompatibility. Poly(ε-caprolactone) is an important biodegradable and biocompatible aliphatic polyester. In this study, poly(ε-caprolactone)/HNT nanocomposites were prepared by in-situ ring opening polymerization of ε-caprolactone in the presence of HNT using Sn(Oct)2 as a catalyst. Morphology, thermal, mechanical properties and shape memory effect of nanocomposites were investigated. |
