Abstract:
The ability of spherical silica containing immobilized nanosilver (SiO2-Ag) to give antimicrobial activity to HDPE films was investigated. The thermal stability as well as barrier properties of the silica filled HDPE films were significantly better compared to the neat polymer. Moreover, higher silica contents resulted in higher storage modulus, proving that the material became stiffer. Improved resistance to microorganisms (E. coli, S. aureus, S. typhimurium, L. motocytogenes, B. subtilis and P. fluorescens) of the HDPE films containing SiO2-Ag was also observed whereas pure HDPE did not show this activity.
