Synthesis of silver/polymer colloidal composites from surface-functional porous polymer microspheres

摘要: Abstract This study presents a different colloidal silver (Ag)/polymer system where Ag nanoparticles are deposited uniformly onto surface-functional porous poly(ethylene glycol dimethacrylate-co-acrylonitrile) (poly(EGDMA-co-AN)) microspheres. The formation and morphology of the composite microspheres were characterized from electron microscopy X-ray diffraction analyses. significance present report is that owing to high affinity between nitrile group (CN) on large surface microspheres, having face-centered cubic phase incorporated evenly into deep pores with fine size distribution. In preservation test, Ag/poly(EGDMA-co-AN) obtained showed an excellent anti-bacterial performance, elucidating applicability for new preservative.
