Abstract
A silicone-modified fluoropolymer is formed by first dissolving a fluoropolymer in an organic solvent, the fluoropolymer having at least one monomer of vinylidene fluoride coupled to a hexafluoropropylene monomer unit, and subsequently reacting the mixture with an amino silane coupling agent to form an aminosilane-modified fluoropolymer. The aminosilane fluoropolymer is subsequently heated and partially condensed with an oligomer of a silane compound including alkoxy silane. The resultant composition is suitable for use as a low refractive index layer in an antireflection coating on an optical substrate.
