Abstract
The present invention describes a novel process for the conformal coating of polymer fibers of nonwoven substrates. This process is based on modification of polymer fiber surfaces by controlling the degree of etching and oxidation to improve adhesion of initiators to the surface and to facilitate subsequent conformal polymer grafting. The modified fiber surfaces render new functionalities to the surface, such as increased hydrophilicity, attached ligands or changed surface energy. The invention includes the modified polymer fibers produced by the process described herein.
