Abstract
The present study focuses on extracting chitosan from crustacean shells. The as-prepared chitosan was used to develop a uniform thin layer coating on titanium alloy (Ti6Al4V) implant material. Shellac, a natural resin was used intermediately for providing better adhesion. Taguchi optimization technique was used to optimize the control parameter values. Dipping duration and concentration of shellac were considered as control parameters and adhesion strength & thickness of the coating were considered as response characteristics. The concentration of shellac significantly affected the adhesion strength, whereas the thickness increased with an increase in dipping duration. Cytotoxicity tests and corrosion studies were performed on the samples coated with optimal values. The chitosan-coated sample was found as non-toxic and also showed better corrosion resistance.
