摘要（英）：

The invention relates to a method for producing a quaternary ammonium chitosan/polyving akohol membrane, comprising the following steps: (1) synthesizing the quaternary ammonium chitosan; (2) washing and drying the quaternary ammonium chitosan; (3) synthesizing the quaternary ammonium chitosan/polyving akohol membrane; and (4) scraping the quaternary ammonium chitosan/polyving akohol membrane on a flat plate and forming the quaternary ammonium chitosan/polyving akohol membrane. Compared with the prior art, the method for producing the quaternary ammonium chitosan/polyving akohol membrane adopts the raw materials of rich source and low cost, is easy and is convenient to operate.
