Characterization and synthesis for a novel schiff's base of chitosan was investigated. Swell ability of schiff's base of chitosan in different buffered solutions was shown to be higher than that of native chitosan in all investigated pH values. The antimicrobial activities of both chitosan and its schiff's base towards E. coli, S. aureus, A. niger and Candida albicans were investigated and found to be stronger for chitosan schiff's base. Chitosan-Crotonaldehyde Schiff's Base (Ch-Cr-SB) coated AZ91E alloy has been synthesized chemically and its metal and dye uptake were investigated in comparison with parent chitosan. The electrochemical corrosion behavior has been also studied for Ch-Cr-SB in aerated 3% NaCl solution containing different concentrations of schiff's base, in the range from 0.03 to 0.075 mM, using different techniques. Results showed that corrosion rate decreases with increasing the polymer concentration or immersion time, however, it increases with increasing temperature from 298 to 328 K.
