Abstract
A coating technique for amorphous fluoropolymer involves adding amorphous fluoropolymer resin to a solvent. The resin solvent mixture is heated to a predetermined temperature above room temperature. The amorphous fluoropolymer resin is dissolved in a heated solvent, and the liquid coating solution is applied to a substrate. The solvent is then removed from the applied liquid coating solution. The coating technique may be employed in connection with liquid core waveguides.
