Films from biodegradable poly‐3‐hydroxybutyrate are treated with chemical reagents to improve their hydrophilicity and biocompatibility. Two approaches are tested: a single treatment with alkali, acids, oxidizing or reducing agents, and a step‐by step treatment of the alkali pre‐activated surface of polymer films with bromine water and amino‐compounds (ammonia or triethylamine). The maximal level of hydrophilicity (the lowest water contact angle and the highest polar component of the surface free energy) is registered after a single treatment with NaOH and after the step‐by‐step treatment. These samples also showed the best adhesion of mouse fibroblasts of NIH 3T3 line on the film surface. So, the proposed methods can be used to enhance hydropilicity and biocompatibility of biopolymer surface. [ABSTRACT FROM AUTHOR] |
