제목 Effect of functional heterocyclic surfactant on the mechanical properties of biodegradable and sustainable bio-nanocomposite
초록 A biodegradable and sustainable bio-nanocomposite (BNC) based on poly(butylene succinate) (PBS)/cellulose nanofiber (CNF)/functional heterocyclic surfactant (HCS) is prepared and its mechanical properties are examined. HCS is synthesized by reacting isosorbide with isophrone diisocyanate and thermally blended with PBS and CNF. While CNFs are strongly aggregated with each other due to powerful hydrogen bonding between CNFs, HCS effectively induces the exfoliation of CNF aggregates and improves the dispersity of CNFs in the PBS matrix during the thermal blending processes. From the results of universal testing machine, it is revealed that BNC shows higher Young’s modulus than pure PBS as a reference. The mechanism of how the structure of surfactant affects the final mechanical properties of BNC is proposed using the model system.
