Abstract
In special applications, such as hospitals and rehabilitation centers, hygienic wood surface with antimicrobial performance is recommendable. In the present study, the antimicrobial property of wood was increased by grafting with 2-(dimethylamino)ethyl methacrylate (DMAEMA). The reaction proceeds via radical polymerization, and analysis via Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, and thermogravimetric analysis confirmed the successful grafting of DMAEMA to wood. The tertiary amino groups of the immobilized P(DMAEMA) were then quaternized by an alkyl halide, and the quaternary ammonium groups at the surface in high concentration proved to be antibacterial. The test against Escherichia coli by means of the optical density method revealed that the bactericidal effect of the modified surface is higher than that of wood and the monomeric precursors of grafting.
