How do cellulose nanocrystals affect the overall properties of biodegradable polymer nanocomposites: A comprehensive review

Cellulose nanocrystals (CNCs) are considered as one of the most attractive renewable reinforcements for biodegradable polymers due to their promising properties and broad range of applications in several fields. However, the knowledge of CNCs effect on the overall properties of these CNC-based nanocomposites is not fully clarified. This review proposes a comprehensive understanding on the effect of CNCs on the rheological, thermal, mechanical, barrier and biodegradation properties of the main biodegradable polymers. This further understanding is expected to facilitate progress in various sectors of nanotechnology and materials science.
