The planned scientific activity concerns the surface engineering of metallic implants. The basic research envisaged in the project will focus on the evaluation of the effect of the addition of Deep Eutectic Solvents (DES) on the microstructure, physical, chemical, biological, and mechanical properties (with particular emphasis on adhesion) of composite coatings electrophoretically deposited (EPD) on the surface of Ti13Nb13Zr titanium alloy. The coatings will be based on chitosan, a polymer of natural origin, with the addition of pro-osteointegration mesoporous bioactive glass nanoparticles (MBGNPs) for bone implant applications. Polysaccharide-based biopolymer coatings, produced on metallic surfaces using the EPD method, are typically characterized by poor adhesion, stiffness, and brittleness, which precludes their use in clinical practice, despite satisfactory antimicrobial and proosteointegration properties. It is therefore crucial to improve their flexibility and durability, which can be achieved by adding plasticizers, nanofillers, crosslinking, or other polymers. The development of technologies for producing such composite coatings on Ti13Nb13Zr titanium alloy will significantly contribute to the development of bioactive titanium implants. Published research results with Gdańsk TECH affiliation will contribute to the development of materials engineering, mainly in the area of biomaterials.
