Transparent bionanocomposite films based on chitosan and TEMPO-oxidized cellulose nanofibers with enhanced mechanical and barrier properties
Carbohydrate Polymers(2016)
摘要
•Bionanocomposite films of TEMPO-oxidized cellulose nanofibers and chitosan were prepared.•SEM and AFM images indicated that TEMPO-CNFs were completely embedded in the chitosan matrix.•Nanocomposite films were less transparent and flexible than 100% chitosan films.•Nanocomposite films possessed higher oxygen barrier properties than chitosan films.•Nanocomposite films had higher thermal stability and mechanical properties than chitosan films.
