Egg white water gel membrane/composite membrane based on unidirectional nanopore dehydration and preparation method thereof

The invention relates to an egg white water gel membrane/composite membrane based on unidirectional nanopore dehydration and a preparation method thereof. Egg white or a mixture solution of egg white is placed in a container with a nanopore filter membrane as the bottom, transparent, fragile and water-soluble egg white bioglass is obtained through unidirectional nanopore dehydration, and after heat treatment, an egg white water gel membrane/composite membrane which is in a wet state, transparent, elastic and high in tensile property is prepared; the tensile strength reaches 5.8 MPa, the breaking elongation is 90-110%, and the swelling rate is 60-130%; and preparing the polypyrrole modified egg white water gel conductive film from the egg white water gel film/composite film through a polymerization reaction. On the prepared egg white water gel film, the mouse fibroblast L929 has good insertion and proliferation. The egg white water gel material based on unidirectional nanopore dehydration provided by the inven
