Electrophoretic deposition of bioactive glass/polymer composite coatings with and without HA nanoparticle inclusions for biomedical applications

Electrophoretic deposition (EPD) methods have been developed for the fabrication of composite bioactive glass–hydroxyapatite (HA)–chitosan and bioactive glass–HA–alginate composite coatings. Two different strategies have been utilized, which are based on the use of cationic chitosan and anionic alginate biopolymers. The mechanism of cathodic deposition of chitosan is based on the pH increase at the cathode surface, whereas the pH decrease at …
