| 摘要 |
The present invention relates to a method for producing a polyvinyl alcohol nano nonwoven fabric, comprising the steps of: producing a spinning solution by dissolving polyvinyl acetate; producing a polyvinyl acetate nano nonwoven fabric by electrospinning the spinning solution; and saponifying the polyvinyl acetate nano nonwoven fabric by adding an acid mixed solution or alkali mixed solution including a dispersion agent, a swelling agent, and a solution and using heterogeneous surface saponification. According to the method of the present invention, compared to a conventional polyvinyl alcohol nano nonwoven fabric, wrinkles and nano pores are formed in a surface thereof, so that a novel polyvinyl alcohol nano nonwoven fabric having an improved specific surface area can be produced. Moreover, the obtained novel polyvinyl alcohol nano nonwoven fabric having an improved specific surface area can be applied to a filter material, a reinforced fiber, and a carrier for culturing a biological tissue, thereby exhibiting improved effects. |
