Title: NANO SILICA-CARBON-SILVER TERNARY HYBRID INDUCED ANTIMICROBIAL COMPOSITE FILMS  

 

Abstract: In this work, Ag assisted biogenic silica-carbon nanoparticles (SCAg NPs) was incorporated into a viscous solution of biopolymer to fabricate antimicrobial thin films by 3D printing. The Ag NPs were developed in situ from AgNO3 through one step ball milling with silica-carbon hybrid obtained from pyrolysis of rice husk. The nanostructure of the SCAg NPs was determined by XRD. The printed films were characterized by XRD, FE-SEM, Raman microanalysis and tensile testing to investigate the influence of nanoparticles on microstructural and mechanical properties. Antimicrobial testing was carried out on the films to assess the inhibitory effect of SCAg NPs on Salmonella Enteritidis inoculum. XRD and Raman microanalysis confirmed the incorporation of Ag particles into SCNPs, while FE-SEM size measurement of the SCAg NPs ranged between 10-100 nm in diameter. Tensile test was carried out to determine the influence of SCAg NPs on mechanical properties of the films.
