Abstract
The present invention relates to a one-pot synthetic method for synthesizing silver-containing waterborne polyurethane (WBPU). The method includes the steps of adding a silver ion-containing solution, such as silver nitrate solution, into WBPU emulsion to form a silver-containing PU emulsion by stirring, and dehydrating the silver-containing PU emulsion so as to obtain a WBPU containing nano-scaled silver particles having a uniform particle size and good dispersibility. The present invention provides a method that can be easily and speedily operated, and the silver-containing WBPU prepared according to the method of the present invention exhibits excellent antibacterial, bactericidal and deodorant effects but using a small amount of silver.
