A biodegradable and sustainable bio-nanocomposite material based on p oly(butylene succinate) (PBS)/cellulose nanofiber (CNF)/heterocyclic surfactant (HS) is prepared by thermal and solution blending processes. Because CNFs easily aggregate due to strong hydrogen bonding between hydroxyl groups, a novel HS is synthesized in this study to enhance the dispersibility of CNF in PBS matrix. From the results of universal testing mechanine (UTM), it is revealed that PBS/CNF/HS bio-nanocomposite shows higher Young’s modulus than pure PBS. This is attributed to the uniform distribution of CNF in PBS where HS induces the effective exfoliation of CNF aggregates during thermal and solution blending processes.
