Novel copolymers that are fluoropolymers including a first repeat unit that is fluorinated and cyclic and a second repeat unit from a trifluorovinyl methylene ether monomer having sulfur or sulfone functionality in the pendant group are disclosed. The copolymers have relatively high gas permeability as a result of a cyclic repeat unit in the copolymer backbone and ionomers from oxidation of the sulfur containing functionality are particularity useful in the cathode structure of a proton exchange membrane fuel cell.

The present disclosure provides a method for enhancing resistance to delamination of a coating layer applied to a rigid, monolithic substrate (204, 404). The method comprises forming a plurality of holes (208, 408) on the substrate (204, 404), to define passages from a first operative surface to a second operative surface of the substrate (204, 404). The first operative surface is coated with a first coating material and the second operative surface is coated with a second coating material, to obtain a first operative surface having a first coating layer (202, 402), and a second operative surface having a second coating layer (206, 406). A portion of the first coating material and/or the second coating material is allowed to flow through the passages to configure contiguous ties (210, 410) between the first and the second coating layer. The contiguous ties formed between the first and the second coating layer aid in enhancing the resistance to delamination of the coating layer applied to the rigid, monolithic substrate (204, 404).

Plant oil-based compounds are provided which possess both low viscosity and high reactive functionality. These compounds are useful in coating and composite applications, as well as related methods. Exemplary compounds can be produced by transesterification of a plant oil triglyceride with a nucleophile reactant, such as a vinyl-functional alcohol, to yield reactive fatty acid-containing monomers.
