Abstract
In the present work, the polymer matrix is comprised of Polyvinyl alcohol and natural polymer starch with the addition of an absorbent clay bentonite. These were effectively blended followed by reinforcement in the form of gold, silver, and zinc oxide nanoparticles. Films were prepared and the dispersion of the nanoparticles was studied by scanning electron microscopy and ultraviolet spectroscopy. The mechanical properties and thermal stability of such nanocomposites as compared to the polymeric blend was studied and an enhancement in properties was observed. Furthermore the use of PVA, bentonite and these nanoparticles in facial masks led to the investigation of cosmetic applications of the polymer nanocomposites thus prepared. This composition was found to be stable in face masks for a period of 12 weeks and reported no irritation when applied to the skin.
