Electrochemical deposition of composite biopolymer films

Composite films of alginic acid–hyaluronic acid and alginic acid–heparin were deposited by electrochemical method for the surface modification of conductive substrates. Obtained films were studied by SEM, thermogravimetric analysis (TGA), differential thermal analysis (DTA) and Fourier transform infrared spectroscopy (FTIR). The deposition yield increased with increasing concentration of hyaluronate and heparin in the alginate solutions. The …
