Synthesis and Properties of a Novel Si-Ti Polymer/Montmorillonite Nanocomposites

Abstract:

Using methyl triethoxysilane, tetrabutyl titanate and ethyl acetoacetate as raw materials, the Si-Ti polymer was synthesized to prepare Si-Ti polymer/montmorillonite nanocomposites. The effects of OMMT content on the impact properties and barrier performance of nanocomposites were investigated. The results show that with the increasing of OMMT content, the impact properties of nanocomposites are improved significantly. The impact strength of nanocomposite with 10wt% OMMT is about twice times than that without OMMT. The gas barrier properties of nanocomposites are also improved significantly. Compared with pure Si-Ti polymer, the water absorption of nanocomposite with 6wt% OMMT is decreased by 60.3%.
