PROCESS AND APPARATUS FOR COATING WITH REDUCED DEFECTS |
摘要 |
A process and apparatus for producing a polymer coating with reduced defects is described. The process includes coating a solution of a polymerizable material and a solvent on a substrate, polymerizing a portion of the polymerizable material, and removing a major portion of the solvent after polymerization of the portion of polymerizable material. A further polymerization of any remaining polymerizable material can occur after removal of the solvent. The apparatus includes a webline for conveying a substrate from an unwind roll to a windup roll, a coating section proximate the unwind roll for coating a solution of a polymerizable material and a solvent on the substrate, a polymerization section downweb from the coating section for polymerizing a portion of the polymerizable material, and a solvent removal section downweb from the polymerization section for removing the solvent after polymerization of the portion of the polymerizable material.
