The disclosure relates to methods for forming an omniphobic thermoset composition, such as an omniphobic polyurethane or epoxy composition. First and second thermosetting components are applied to a substrate and partially cured. A functionalized hydrophobic/oleophobic/omniphobic polymer which is reactive with at least the first thermosetting component is then applied to the coated substrate, which is then further cured to form a thermoset omniphobic coating on the substrate. The thermoset omniphobic composition has favorable omniphobic properties, for example as characterized by water and/or oil contact and/or sliding angles. The thermoset omniphobic composition can be used as a coating on any of a variety of substrates to provide omniphobic properties to a surface of the substrate. Such omniphobic coatings can be scratch resistant, ink/paint resistant, and optically clear. The thermoset omniphobic composition can be applied by different coating methods including cast, spin, roll, spray and dip coating methods.

Embodiments of the present disclosure pertain to a composition that includes a rotaxane. The rotaxane includes a plurality of macrocyclic rings and a polymer with a molecular weight below 10,000 Da that is covalently appended to one or more sterically hindered molecules. The cavities of the macrocyclic rings are threaded onto the polymer. The plurality of threaded macrocyclic rings include a plurality of different segments that each include a plurality of threaded macrocyclic rings. Each of the plurality of different segments is in the form of a crystalline network. Further embodiments of the present disclosure pertain to methods of forming the rotaxanes by covalently appending one or more sterically hindered molecules onto a polymer and threading a plurality of macrocyclic rings onto the polymer. Additional embodiments of the present disclosure pertain to methods of manufacturing a three-dimensional structure by applying a composition of the present disclosure onto a surface.

A trim component for an interior or exterior body of the vehicle includes a substrate formed of a translucent synthetic resin such as polycarbonate, acrylic, polystyrene, polypropylene, ABS/MABS, polypropylene, TPU, PSU, polyamide, polyesters, styrenics, ASA, polysilicone, PETG, PCABS, and/or other resins or combinations of resins, and a paint layer formed on a surface of the substrate. The paint layer formed of the chrome-like high-metallic organic binder is applied over the surface of the substrate. Further, the paint layer is also a clear and translucent finish such that light emitted from a light source is able to pass through the paint layer. The trim component also includes a coating layer formed on the surface of the paint layer.
