Biocidal capability optimization in organic-inorganic nanocomposites based on titania.

Optimization of the interfacial agent content in biocidal titania-isotactic polypropylene nanocomposites is performed by evaluating their structural, thermal, optical, and biocidal properties. The balance between the photochemistry (photokilling) behavior and the thermal properties is achieved in the nanocomposites with an incorporation of 2 wt.% in inorganic nanoparticles (Tio2) using a compatibilizer content ranging from 50 to 80 wt.% with respect to the titania amount
