Design of Extruded Nanostructured Composites via Decoupling of the Cellulose Nanofibril/Poly(butylene adipate-<i>co</i>-terephthalate) Interface.

ABSTRACT: The full exploitation of the outstanding mechanical properties of cellulose nanofibrils (CNFs) as potential reinforcements in nanocomposite materials is limited by the poor interactions at the CNF-polymer matrix interface. Within this work, tailor-made copolymers were designed to mediate the interface between CNFs and biodegradable poly(butylene adipate-co-terephthalate) (PBAT), and their effect on extruded nanocomposite performance was tested. For this purpose, two well-defined amphiphilic anchor-tail diblock copolymer structures were compared, with a fixed anchor block length and a large difference in the hydrophobic tail block length. The aim was to evaluate the impact of the copolymers' chain length on the nanocomposite interface. The presence of amphiphilic diblock copolymers s
