Abstract
A permanent hydrophilic modification for fluoropolymer substrates is described in which the substrate is coated with a film of a charged polyelectrolyte complex. The film has cationic and anionic components in which the charges on the components interact to form stable electrolytic bonds.
Claims5
A permanently hydrophilically modified fluoropolymer comprising a fluoropolymer having a surface, said surface having a thin film of a charged polyelectrolyte complex formed on the surface of the fluoropolymer and in which the polyelectrolyte complex consists essentially of a complex of:
- (a) a water soluble polycation and/or a cationically modified synthetic resin;
- and
- (b) a water soluble anionically modified hydrophilic synthetic resin.
