Preparation method for molecular sieve/organic composite permeable vaporization membrane

The invention belongs to the field of membrane separation and particularly relates to a preparation method for inorganic/organic high polymer composite permeable vaporization membrane taking molecular sieve materials as a separation layer and an organic high polymer microfiltration membrane as a support body. The composite membrane can use permeable vaporization to enable organic matters in organic systems such as alcohols, ketones, amines and the like to pass through preferentially, so as to achieve the separation of organic matters and water.
