Abstract
A method of preparing a polyvinyl alcohol nanofiber membrane includes a material for controlling cell specific adhesion, and a nanofiber membrane that can maintain cellular functions such as cell activity and growth is prepared by adding aqueous solutions containing a polyacrylic acid and a glutaraldehyde crosslinking agent in a polyvinyl alcohol and materials capable of enhancing or regulating cell adhesion, electrospinning, treating with hydrochloric acid vapor and dimethylformaldehyde solvent and treating with sodium hydroxide to control the cell adhesion.
