Industrial and consumer polymers can be susceptible to microbial attack, causing undesirable effects such as staining, odors, and physical degradation. Bacteria and fungi feed on most plastic and polymer additives often leading to a potential loss of product integrity. Extensive research has been carried out in the last decades in order to investigate possible methods to prepare antibacterial plastics. Antimicrobial plastic, polymers and composites provide excellent benefits. Antimicrobial additives (masterbatches) offer valuable protection for polymers. They are incorporated into a wide variety of plastics and polymeric materials to prolong their life, maintain their aesthetic appeal, or reduce surface contamination. Polyamide (PA) is a polymer, which contains recurring amide groups as integral parts of the main polymer chain. Nanoparticles of ZnO are being used industrially for modifications of plastics. A common feature is their antibacterial activity. The antibacterial activity of them has been demonstrated against human pathogenic bacteria, mainly E.Coli and S.aureus.
