Preventing bacterial attachment to material surfaces in the absence of antibiotic agents is currently demanded due to the growing prevalence of antimicrobial resistance strains in the food industry and healthcare industry. In this work, we prepared “surface energy reducing silica” (SERS) with reaction of silica nanoparticles and fluorosilane. The mixture of SERS and low-density polyethylene (LDPE) film was prepared via solvent casting method. Casted film showed CF3 peak during FT-IR measurement and high-water contact angle. The bacterial anti-adhesive property of modified film was evaluated with Escherichia coli and Staphylococcus epidermidis at bacterial concentration of ca. 9.0 log CFU/mL through the dip-inoculation approach. Self-cleaning property was investigated with various organic/inorganic contaminants (e.g., protein, blood, soda, soil etc.). The mechanical robustness of the film surfaces was assessed through ultrasonic test method. |
