This paper addresses the effects of operating variables on mechanical properties of polyester/clay nanocomposites including tensile strength, percentage elongation etc. The variables were clay type, clay content, and prepolymer–clay mixing type. The experiments were carried out based on the design of experiments using statistical methods. The nanocomposites were synthesized via in situ polymerization of polyester and clay (dissolved using styrene monomer) with Methyl-ethyl ketone peroxide (MEKP) as catalyst in Cobalt base accelerator. Unmodified Kaolinite clay and Vinyl silane modified clay are the two types of clay examined. The parameters studied, clay type and mixing method are found to have significant effects on mechanical properties. Polyester nanocomposites showed larger improvements in mechanical properties compared to pristine polyester, especially when sonicator type of mixing is employed due to the favorable shear forces exerted by polymer matrix on clay aggregates during polymer–clay mixing. It is observed that the stress and elongation at break of the nanocomposite samples can be optimized with a particular percentage of clay loading. Characterizations of the nano composites were also made using techniques like SEM.

Clay Type

Epoxy-clay nanocomposites have recently gained considerable attention due to their interesting physical, thermal and mechanical properties. These properties, however, depend on a number of parameters such as the clay type, clay modifying agent, polymer matrix and the adopted mixing process. In the current work, epoxy-clay nanocomposites were prepared from Araldite GY6010 CRS and Nanomer I.30E nanoclay using different sonication (mixing) periods (5 to 60 minutes) and different concentrations of clay (2 to 5%wt). The effect of sonication time and clay loading on the tensile and hardness properties of the resulting nanocomposites were investigated. The results showed that the ultimate strength and fracture strain of the nanocomposites were below that of the neat epoxy, but the elastic modulus was generally enhanced by the addition of the nano-clay content. Increasing the sonication time enhanced the tensile strength on the expense of reducing the modulus of elasticity. Hardness of the nanocomposites did not show significant change with either the addition of clay or processing under different sonication times.
