Abstract

This study investigates the incorporation of different size and shape nanofillers on the properties of PET nanocomposites. PET was reinforced with 0.3 wt.% of four different shape/size nanoreinforcements, namely: 1D platelet-like shape organo-modified layered silicates (montmorillonite) with average particle sizes (i) 30 μm and other with (ii) 8 μm; (iii) 3D spherical shape titanium oxide with average particle size of 21 nm and (iv) 3D spherical shape silica with average particle size of 12 nm. PET nanocomposites were prepared by melt blending in an asymmetric batch minimixer followed by compression moulding process for sample preparation. The effect of nanofillers upon thermal, mechanical and structural properties in comparison to the neat PET is discussed.
