Abstract
Bionanotechnology deals with nanoscopic interactions between nanostructured materials and biological systems. Recently polymer nanocomposites with enhanced biocidal activity have attracted great attentions. Nanotitanium dioxide (TiO2) is considered as an active nanofiller in manufacturing surgical devices and implants with antibacterial activity. Nano TiO 2 can also behave as photosensitizer for Polyethylene, hence makes the product photodegradable and photoactive towards various bacteries when irradiated by UV. However, nano TiO 2 can not improve barrier properties due to its low aspect ratio. In the present work, a hybrid system composed of nano TiO 2 and nanoclay with negatively charged silicate layers, has been incorporated into film grade polyethylene. Nanostructure has been tailored to maximize photocatalytic behavior for the deactivation of E-colie. Nanocomposites exhibited synergized antibacterial activity with enhanced barrier towards penetrating molecules. Nanocomposites showed also accelerated photodegradation when exposed to the solar light. Keyword: Nanocomposites, NanoTiO2 , Nanoclay, Hybride, Antimicrobial, Polyethylene
Biography
I received MSc and Ph.D degree in polymer engineering at Birmingham University of England. Academic activity was started in 1981 at polymer engineering department of Amirkabir University in Tehran. My main research activities have been focused on microstructure- properties correlation of polymer nanocomposites and nanobiomaterials. I am currently full professor at this department and published over 90 international papers
