The chitosan coating is applied using the dip coating (DC) method. The corrosion protection efficacy is evaluated using various electrochemical techniques. The results show that the DC-made chitosan coating acts as a strong physical and chemical barrier, inhibiting corrosion in the aggressive NaCl environment. The corrosion rate of carbon steel increases with higher temperatures, suggesting a physisorption mechanism for the chitosan coating. The DC technique exhibits a high inhibition efficiency of 73%. This study highlights the potential of chitosan as a corrosion inhibitor for carbon steel in environments and emphasizes the practicality and cost-effectiveness of the dip coating method. Further research can explore the optimization of the chitosan coating process and its performance in different corrosive environments for long-term corrosion prevention. specialized Zainor Aqilah Binti Mohd Ruzaini Faculty of Chemical and Process Engineering Technology Bachelor of Chemical Engineering -- Universiti Malaysia Pahang Al-Sultan Abdullah - 2024 Include bibliographical reference Faculty of Chemical and Process Engineering Technology Dissertations Universities and colleges Dissertations Theses Dissertations THE0010657 (Local) https://umpir.ump.edu.my/id/eprint/47175 https://umpir.ump.edu.my/id/eprint/47175 UMPSA 260702 20260702184230.0 eng
