The bioactive coating, chitosan, bonded to titanium is one option to both reduce post-operation infections and improve the osseointegration of implants. Chitosan, which is a biopolymer, has been successfully bonded to titanium through the use of the linker molecule, aminopropyltriethoxysilane (APTES), deposited using heptane. While successful bonding has occurred, long term storage on the behavior of the silane or the coating has not been examined, nor has long term exposure of the coating to simulated body fluid. The research presented continues the examination of adhesion strengths of these chitosan coatings by examining the surface behavior of the linker molecules after several weeks of exposure to the solvent, as well as the adhesion behavior of the chitosan after several weeks of exposure to the atmosphere and to simulated body fluid. The ability of the coating to remain strongly adhered to the titanium under non-ideal conditions will be explored.
