Development And Characterization Of Self-healing Car Paint Using Chitosan

Car surfaces are vulnerable to scratches from environmental conditions, thereby prompting car users to visit car workshop for re-spray. This process does not usually bring permanent solution to scratches on car surfaces since they are often re-spray with non-self-healing paint. The aim of this work was to develop self-healing car paint. In doing this, response surface methodology (RSM) was used to obtain an optimum paint formulation which was then improved into a self-healing car paint by incorporating chitosan into the formulation, sprayed on substrates, allowed to dry, scratched with a pin, …
