Influence of nanoclay amount on surface properties of the nanocomposites was investigated using Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), contact anglemeasurement, scanning electron microscopy (SEM) and Transmission spectroscopy (TS). Polypropylene based nanocomposites containing various loads of nanoclay were prepared by melt compounding. X-ray diffraction (XRD) characterized the dispersion of nanoclay in polymer matrix. AFM and SEM Studies have shown increased in surface roughness by raising the amountof nanoclay. Contact angle measurements of the resultant nanocomposites also shown improvement in wettability related to disperse part of surface tension
