Antibacterial Polymeric Nanocomposites with Matrix of PET and TiO2 Functionalized Nanoparticles with Application in Medical and Food Industry
Journal Title: Proceedings of the International Conference on Advanced Materials and Systems (ICAMS) - Year 2018, Vol 1, Issue
Abstract
Thermoplastic polyesters represent an important class of polymers used in a variety of productsand applications, one of which is poly (ethylene terephthalate) (PET). Currently, PET is the mostcost-effective polyester. PET can be processed in a variety of domestic and industrial shapes andproducts by melt processing techniques such as spinning, extrusion,injection, blowing,thermoforming. Polymer composite materials are systems consisting of one or more discontinuousphases dispersed in a continuous phase. In this paper, elastomeric nanocompound materials wereselected, due to performance properties such as: antimicrobial, resistance to aggressive chemicalagents, mechanical properties, especially hardness which, depending on the degreeofplastification, can present valuesfrom very low to high 30-100°Sh D, thermal, impermeability,resilience, low density, elasticity, thermostability, processability, impact resistance etc. The newcompounds produced by a simple and efficient technology for obtaining polyethyleneterephthalate (PET) composite,TiO2functionalizednanoparticles, provide flexibility in adaptingsuperficial chemistry and molecular structure to the polymer / nanoparticle interface. Thesenanomorphic molecules form the“molecular bridges”between individually dispersedcompounding agents and the continuous phase polymer matrix resulting in a maximizedperformance of the composite material by optimized interface compatibility and bonding.
