Fabrication of composite coatings based on chitosan and bioactive glasses via electrophoretic deposition
Supervisors: Asim Muhammad Akthar, Prof. Aldo R. Boccaccini
For a successful implantation of a total joint replacement a certain bioactivity and osseointegration is required by the implant. Both characteristics are dependent on the implant surface which can be adjusted by a coating . Due to its versatility and ability to process a wide field of materials at room temperature electrophoretic deposition (EPD) is a widely used method for coating substrates . For increasing the bioactivity, bioactive glass is an often used material, since it shows an excellent osteconductivity and osteogenic potential. By adding the natural polymer chitosan to the coating a better mechanical stability and controllable degradation rate of the coating can be achieved .
