Project title: Clay-Polymer Nanocomposites materials

Polymer nanocomposites are novel materials reinforced with very low loadings of silicate clays such as vermiculite, montmorillonite, saponite, etc.  The clays are normally undergo ion exchange with  cationic surfactants like R-NH3+ to improve their compatibility with the polymeric matrix. Such organoclays are melt-compounded with thermoplastics such as polyamide, polypropylene or polyethylene. The silicate platelets are dispersed and exfoliated within the polymeric matrices, leading to the formation of exfoliated nanocomposites.  In this project, the crystallization, mechanical (tensile and impact), fracture toughness and thermal behavior of polymer nanocomposites will be investigated.
