Preparation of a crosslinked coating containing fluorinated water-dispersible polyurethane particles

• A novel crosslinked coating matrix containing fluorinated water-dispersible PU particles.
• Outstanding transparency, liquid repellency, and adherence to various substrates.
• Excellent corrosion resistance as well as a high degree of glossiness.

The development of new polyurethane (PU) derivatives can readily enhance the properties of a diverse range of polymeric materials. Herein, we report a novel crosslinked coating matrix, which contains uniformly distributed fluorinated water-dispersible PU particles both on its surface and interspersed throughout its matrix. The desirable distribution of the functional particles results in a coating with outstanding transparency, liquid repellency, and adherence to various substrates. In addition, the coating provides the substrates with excellent corrosion resistance as well as a high degree of glossiness. The developed structural design is anticipated to give an inspiration for the functionalization of PU-based materials with applications in various fields.
