摘要：
Gelatin from porcine skin was functionalized by introducing furan containing photo-sensitive moieties pending chromophores. The water solubility of furan-modified gelatin was lost after the exposure to ultraviolet light, indicating the effectiveness of the photo-crosslinking process. The light absorption capacity of the modified gelatin before and after the exposure was studied using UV spectroscopy. The properties of the final material were analyzed by contact angle measurements. Hereby, a "green" strategy for the photochemical cross-link of gelatin using renewable resources and in absence of initiators is proposed. (C) 2015 Elsevier B.V. All rights reserved.
