The invention discloses an anti-fouling polyurethane thin film with high elasticity and high transparency, a preparation method and use thereof. The raw materials of the polyurethane thin film include the following active ingredients by mass fractions: 30% to 40% of a hard segment monomer, 40% to 50% of a soft segment monomer, 3% to 6% of a hydrophilic monomer, 0% to 3% of a crosslinking monomer, 0% to 5% of a small molecular chain extender, and 10% to 15% of a compound with low surface energy. A chemically and physically double-crosslinked anti-fouling polyurethane is synthesized through a polycondensation reaction. This thin film exhibits superior low adhesion and anti-fouling properties, and can achieve the coexistence of both low adhesion and stretchability at the same time.

The disclosure relates to a field of functional coating technologies, and particularly to a durable inorganic super-hydrophilic paint, a preparation method and an application thereof. The durable inorganic super-hydrophilic paint includes the following preparation raw materials in percentage by mass: 30&#x2dc;60% silicate, 5&#x2dc;25% zinc oxide, 10&#x2dc;40% water and 0.1&#x2dc;5% wetting agent. The coating formed by a durable inorganic super-hydrophilic paint prepared by the method is a flat rigid coating, with good appearance, excellent antifouling self-cleaning and anti-microbial adhesion properties, long-term underwater stability and high mechanical strength. The paint may be applied to building external walls and home inner walls for its antifouling self-cleaning property and may be applied to a field of oil field and oil-water separation for its excellent underwater oleophobic property.
