Huang, Ye; Peng, Guangjia; Chen, Bin; Yong, Ping; Yao, Nan; Yang, Liming; Pirraco, Rogério P.; Reis, R. L.; Chen, JieIn order to ameliorate the properties of corrosion resistance and achieve applications in anti-biofouling of 316L stainless steel (SS), a sulfated derivative of chitosan was deposited onto stainless steel surface by an electrochemical method. In detail, chitosan-catechol (CS-CT) was synthesised in the hydrochloric acid solution by the Mannich reaction and then electrodeposited on the surface of the polished 316...
