文摘
- •
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.
