The invention provides a polyethylene fluorine-containing double-sparse material, a coating containing the same and a preparation method thereof. The double sparse material has the following structural formula I: Structural Formula I wherein m is from 20 to 300 and n is from 2 to 4. The large fluorine atom having the fluorine-containing resin amount of the above structural formula I is introduced into the polyvinyl alcohol unit segment, so that it is insoluble in water and insoluble in organic matter. Moreover, the above double-sparing material of the present application can be obtained by using a perfluoroacid fluoride and a polyvinyl alcohol for the mixture polymerization, and the preparation method is simple, and the raw materials are all conventional raw materials, and the production cost is low. |
