Recently, the new type of polymer nanocomposites has been reported with high improved properties over neat polymers (Zhang et al., 2003; Leuteriz et al., 2003). Nylon was the first commercially successful synthetic polymer, consist of segments of polyethylene (CH 2 )n separated by peptide units (NH-CO) which are parallel or ant- parallel: Nylon-n:-[-(NH-CO)-(-CH2)n-]- (1) Nylon-m,n:-[-(NH-CO)-(CH2)n-2-(CO- NH)-(CH2)m-]- (2) The unit of the peptide was provided hydrogen bonding between polymer chains giving nylon some of its unique properties (Dasgupta et al., 1996). Nylon is a polar synthetic polyamide can be prepared from adipoyl chloride and hexamethylene diamine to form a linear nylon 6,10. It is particular nylon is made of units of 6 carbons between two nitrogen atoms, an amide linkage, another unit of 10 carbons (Beecroft and Ober, 1997). Metal nanoparticles have several applications in the various areas such as catalysis (Ying et al., 1999), magnetic (Morey et al., 2000), biomedical materials (Kong and Jang, 2008) and optoelectronic (Liu et al., 1998; Schneider et al., 2000). The metal/polymer nanoparticles have the International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 5 Number 4 (2016) pp. 935-941 Journal homepage: http://www.ijcmas.com Silver nanoparticles was synthesized by reduction method and used for loading nylon 6,10 to form Ag/nylon 6,10 nanocomposite.The nanocomposite was characterized by X-ray fluorescence (XRF). The antibacterial activity was performed against Escherichia coli and the effective antibacterial activity observed for Ag/nylon nanocomposite at different concentration of silver nitrate.
