When it is applied as a single component coating, the alkyl-chitosan derivative (ACh) leads to a slight increase of the contact angle value (+1.7°) and, in both composite and successive coatings, it changes the hydrophilic character of MFC to hydrophobic, increasing the CA value by up to 85°, compared to single-component MFC coatings. On the opposite side, all carboxymethyl chitosan (CCh) based coatings show hydrophilic
