Abstract
|
Alginate coatings were fabricated by electrophoretic deposition (EPD) using alcohol (methanol,
ethanol and isopropanol)-water mixtures at different ratios. Water electrolysis and so current
density increased with water content and EPD time leading to the more bubbles in
coatings. EPD rate increased with water amount due to the increase in concentration of H+
and Alg− ions and reduction in solution viscosity. According to the results of kinetics, optical
microscopy and corrosion analyses the coating deposited at 10 V for 1 min from the
ethanolic solution with 60 vol.-% of water was selected as the optimum coating for in-vitro
cell culture and antibacterial analyses. There was almost 30% rise in cell expansion for the
sample with optimum coating after 7 days compared to the blank. Also, the coated sample
showed antibacterial activity against Bacillus bacteria.
