Abstract
The disclosure relates to a self-healing omniphobic composition including a self-healing omniphobic polymer with a crosslinked backbone. The crosslinked backbone includes a reaction product between a polyisocyanate, a functionalized omniphobic polymer reactive therewith, a reversible polyfunctional linker including a hindered secondary amino group and/or an aromatic hydroxy group, and one or more polymeric backbone components. The crosslinked backbone includes reversible urea or reversible urethane bonds between the reversible polyfunctional linker and the polyisocyanate, which in turn provide self-healing properties to the omni-phobic composition. The self-healing omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The omniphobic composition can be used as a coating on any of a variety of substrates to provide self-healing omniphobic properties to a surface of the substrate. Such self-healing omniphobic coatings can be scratch resistant, ink/paint resistant, and optically clear.
