However, chitin films naturally present.in many organisms have not been isolated and characterized. Herein, structurally intact chitin films were successfully extracted from the dorsal pronoturn and the wing of cockroach. Despite using the same extraction procedure, important differences were observed. Especially, hydrophobicity, transparency, antifungal and antibacterial biofilm activities of wing chitin film were recorded notably higher than those of chitin film from the dorsal pronotum. However, better mechanical properties were observed for chitin film from the dorsal pronotum. Notably, among the tested bacteria, two common pathogens could not form biofilms on the surface of the films. This study clearly demonstrated natural chitin films obtained from an insect can provide a new perspective to chitin-based applications where chitin films with high thermal stability, transparency, resistance to bacterial biofilm formation and antifungal activity are needed.eninfo:eu-repo/semantics/closedAccessBlaberus GiganteusBiodegradable FilmAntimicrobialHydrophobicityArticle16316216910.1016/j.carbpol.2017.01.02228267493Q1WOS:000396955500019N/A
