摘要：

The hybrid films of bio-polyurethane (Bio-PU) and silver-doped hydroxyapatite (HA-Ag) for breathable and antibacterial textile applications. The Bio-PU was synthesized using a mixture of castor oil based polyol with petroleum based poly(ethylene glycol). Silver doping to hydroxyapatite(HA) was carried out through ion exchange mechanism between calcium ion in HA and silver ion (Ag+) in aqueous solution of AgNO3. The concentration of Ag+ was controlled to 100-300 ppm. The existence of silver in HA was proved using SEM-EDS while the silver doping amount was estimated by measuring residual concentration of Ag+ after doping using ICP-OES. It was found that the hybrid films exhibited excellent antibacterial activity against bacteria of S. aureus and K. pneumonia by showing 99.9 % reduction of bacteria.
