N2 - This study reports the synthesis and characterization of novel multi-walled carbon nanotube (MWCNT)-amino cellulose composites with enhanced electrochemical and physicochemical properties. Cellulose derivatives (ACEL-1 and ACEL-2) were functionalized with β-amino alcohols and integrated with acid-treated MWCNTs. Structural and electrochemical analyses confirmed a strong synergy between the components, leading to superior corrosion inhibition of C-steel, achieving up to 98.67 % efficiency. The inhibition mechanism was attributed to adsorption, chemical bonding, and the physical barrier effect of MWCNTs. Density functional theory (DFT) and molecular dynamics simulations further supported the strong interaction and stability of the composites on Fe surfaces. Surface analysis using SEM measurements confirmed the adsorption of inhibitors on the metal surface, demonstrating their protective effect against corrosion. These findings highlight the potential of MWCNT-amino cellulose composites for multifunctional applications, including corrosion protection and advanced cellulose material development.
