Title:
OIL REPELLENT COATING MATERIAL, OIL-WATER SEPARATION FUNCTIONAL MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/029030
Kind Code:
A1
Abstract:
An oil repellent coating material, an oil-water separation functional material, a preparation method therefor and a use thereof. The oil repellent coating material comprises a cross-linked network structure which is formed by means of the intermolecular interaction of two or more ionic compounds, wherein at least two ionic compounds carry opposite charges. The oil-water separation functional material comprises a porous substrate and the oil repellent coating material, the oil repellent coating material being distributed at least on a surface of the substrate and on a through-hole wall. The oil repellent coating material and the oil-water separation functional material have the characteristics of super hydrophilicity, underwater super oleophobicity and low oil adhesion, have stable performance in the environments of acids, alkalis and various salt solutions, and may be applied to oil pollution-resistant surfaces, self-cleaning surfaces, oil/water separation, oil-water emulsion demulsification and many other fields.
