Lignin esters were synthesized by reacting lignin with various carboxylic acid chlorides as well as by grafting/ring opening polymerization of DL-lactide and e-lactone. The obtained organosoluble lignin derivatives were used to fabricate blend films with cellulose on silica supports by spin coating. Film morphology, surface chemical composition and wettability of the bicomponent thin films were determined by atomic force microscopy, water contact angle and IR measurements.<br/>Furthermore, the interaction of proteins with the bicomponent surface was investigated by adsorption of BSA under various conditions.
