Enhanced antibacterial activity of NR latex gloves with raspberry-like PMMA-N,N,N-trimethyl chitosan particles.

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.

PMMA-N,N,N-trimethyl chitosan nanoparticles for fabrication of antibacterial natural rubber latex gloves.

This paper presents one-pot synthesis of N,N,N-trimethyl chitosan (TMC) stabilized poly(methyl methacrylate) (PMMA) latex particles via the miniemulsion polymerization technique. From (1)H NMR, synthesized TMC contains 52% degree of quaternization. Compared to native biopolymer chitosan, TMC possesses permanently positive charges as well as provides greater antibacterial activity.
