Abstract
A hydrophobic, self-healing coating includes a vitrimer film having a silicone polymer network crosslinked with dynamic covalent bonds including a boronic ester, where the vitrimer film has a thickness of less than 1000 nm, and where the dynamic covalent bonds provide a mechanism for self-healing of the vitrimer film.
Claims20
A hydrophobic, self-healing coating comprising:
- a vitrimer film comprising a silicone polymer network crosslinked with dynamic covalent bonds comprising a boronic ester,
- wherein the vitrimer film has a thickness of less than 1000 nm, and
- wherein the dynamic covalent bonds provide a mechanism for self-healing of the vitrimer film.
A coated substrate displaying self-healing capability and hydrophobicity comprising:
- a substrate comprising a metal, an alloy, a ceramic, a glass, and/or a semiconductor;
- a vitrimer film on the substrate, the vitrimer film comprising a silicone polymer network crosslinked with dynamic covalent bonds comprising a boronic ester,
- wherein the vitrimer film has a thickness of less than 1000 nm, and
- wherein the dynamic covalent bonds provide a mechanism for self-healing of the vitrimer film.
1 more element
