Mechanical, rheological and degradation properties of PBAT nanocomposites reinforced by functionalized cellulose nanocrystals

摘要

Graphical abstractDisplay OmittedHighlights?Functionalized cellulose nanocrystals (CNC) exhibit higher thermal stability.?Functionalization of CNC improves the dispersion and interaction with polymer matrix.?Good dispersion and interaction lead to nanocomposites with improved properties.AbstractIn this study, the effects of cellulose nanocrystals modified with octadecyl isocyanate on rheological, mechanical and degradation properties of nanocomposites based on poly (butylene adipate-co-terephthalate) (PBAT) were reported. Nanocomposites were prepared by melt mixing procedure of PBAT with 3, 5 and 7?wt% cellulose nanocrystals. The increase of PBAT-based nanocomposites mechanical strength was discussed as a fu
