title: Enhanced antibacterial activity of NR latex gloves with raspberry-like PMMA-N,N,N-trimethyl chitosan particles.
abstract: Raspberry-like poly(methyl methacrylate) (PMMA) latex particles stabilized with silica nanoparticles (SiNPs) were prepared via the Pickering emulsion polymerization for use as substrate of N,N,N-trimethyl chitosan (TMC) adsorption. With the aims to simultaneously reduce the surface friction and improve the antibacterial activity of rubber gloves, the synthesized PMMA-SiNPs(TMC) particles were electrostatically deposited onto a sulphur prevulcanized natural rubber (SPNR) latex film. From SEM and AFM analyses, the results showed the highest surface coverage of PMMA-SiNPs(TMC) particles on the surface of SPNR film of 41% and the surface roughness of 69nm. The coated SPNR film exhibited effective antibacterial activity especially against S. aureus. Therefore, this investigation would be useful for fabrication of special gloves with antibacterial properties.
