A durable solid and liquid repellant material is provided having an elastomeric matrix with a plurality of lubricating domains distributed therein formed by a partial crosslinking reaction between an elastomeric precursor having a first reactive functional group and a polyol having a second reactive functional group. The polyol has a limited solubility circle. The first reactive functional group is selected from the group consisting of: alkene, amine, carboxylic acid, hydroxyl, isocyanate, and combinations thereof and the second reactive group is selected from the group consisting of: amine, carboxylic acid, hydroxyl group, and combinations thereof. The partially crosslinked elastomeric matrix has a crosslink density of greater than or equal to about 200 mol/m3 and less than or equal to about 2,000 mol/m3. Methods for forming the durable solid and liquid repellant material are also provided.
A durable solid and liquid repellant material comprising an elastomeric matrix having a plurality of lubricating domains distributed therein formed by a partial crosslinking reaction between an elastomeric precursor having a first reactive functional group and a polyol having a second reactive functional group, a dispersion (δD) solubility parameter of less than or equal to about 22 MPa1/2, and a polar (δP) solubility parameter of less than or equal to about 20 MPa1/2, wherein the first reactive functional group is selected from the group consisting of:
A durable solid and liquid repellant material comprising an elastomeric matrix having a plurality of lubricating domains distributed therein formed by a partial crosslinking reaction between an elastomeric precursor having a first reactive functional group and a polyol, wherein the elastomeric precursor forms a polymer selected from the group consisting of:
