Polymer/ clay nanocomposites (PCNs) have attracted both industrial and academic interests. This is due to the remarkable improvement that nano-sized-layer-filed polymers in both thermal and mechanical properties at low clay contents (< 5 wt %) compared to unreinforced polymers (Karger-Kocsis, 1995). Their unique properties include higher heat distortion temperature, advanced modulus and heat strength, barrier properties including permeability, higher heat distortion temperature, better scratch resistance and retained optical clarity.
The formation of exfoliated and interculated structures in nanocomposites modifies the characteristics of the polymer, hence affecting the overall properties of nanocomposites.
The Aim of the project is to study the effect of water absorption on the mechanical properties on the Vinyl ester based nanocomposites which are to be prepared by compression moulding technique and the effects of the clay on mechanical properties of nanocomposites fracture behaviour. Three different types of samples (0, 1, 2 and 3 wt % layered silicate reinforced) for mechanical properties investigation will be used.
Different concentrations of nanoclay samples will be fabricated and mechanical testing will done, similarly WAXD will be applied to gauge the structural characteristics of clay and its distribution,rate of dispersion in thermoplastic matrix and the
