Abstract
This study aimed to investigate the electrophoretic deposition (EPD), microstructure, properties, and microbiological activity of multi-component curcumin/chitosan coatings strengthened with cellulose nanofibers (CNF) and carboxymethylcellulose (CMC) on titanium substrates. The findings indicated that pure cellulose dispersed systems had a negative zeta potential, indicating the mechanism of chitosan molecules being adsorbed on the surface of dispersed additives and co-depositing with them on the cathode. CMC and chitosan form a hydrogel-like polyelectrolyte complex structure in a dispersed system, preventing the possibility of obtaining homogeneous coatings via EPD regardless of the process parameters. However, coatings containing CNFs proved to be homogeneous and exhibited high adhesion strength and enhanced scratch resistance, and thus have been selected as the most promising. Their microstructure consisted of submicrometric spherical curcumin particles and CNFs of various sizes homogeneously embedded in the chitosan matrix. Elaborated materials exhibited increased surface roughness compared to the uncoated substrate, as well as moderate hydrophobicity (water contact angle 92.4° ± 1.2°). Electrochemical studies confirmed that the CNF/curcumin/chitosan coatings improved corrosion resistance compared to the bare titanium substrate and the coating without CNF. The CNF/curcumin/chitosan surface also showed significant activity against S. aureus ATCC® 25,923 in terms of bactericidal activity and against biofilm formation.
