dc.description.abstract	Abstract: Self-stratifying coating produces multicoat films by single-coat application, which offers superior performance by enhancing both the adhesion and surface properties simultaneously, suitable for many special coatings and industrial applications. Here, we have developed a well-defined multifunctional self-stratifying coating material with self-healing abilities from blending two copolymers based on fluorous/thiol/siloxane. Combinations of silyl copolymer (PMEA-co-PCMA-co-PTEPA) and fluorous copolymer (PMEA-co-PCMA-co-PHFA) offer spontaneous stratification into three layers with a gradient behavior. This transparent (>90% transmittance) coating provides a highly hydrophobic surface with good hardness (28 MPa). The polymer coating self-repairs under UV light with >80% efficiency. In addition, the healing is also conceivable by heating at 70 °C or by spraying amine due to the thiol-Michael reaction.	en_US
