Effect of Functional Heterocyclic Surfactant on the Mechanical Properties of Biodegradable and Sustainable Bio-Nanocomposite |
| 초록 |
A biodegradable and sustainable polymer nanocomposite (BSPN) is prepared and its mechanical properties are examined in this study. Conjugating isosorbide and isophorone diisocyanate results in the formation of a functional heterocyclic surfactant (HCS). BSPN is then produced by thermally blending HCS with poly(butylene adipate terephthalate) (PBAT) and cellulose nanofiber (CNF). While CNFs are intrinsically highly aggregated with each other due to strong hydrogen bonds between them, HCS induces effective exfoliation of aggregated CNFs and also CNF dispersion in the PBAT matrix during the thermal blending process. BSPN exhibits superior mechanical properties to pure PBAT, which is due to the unique interaction between PBAT and well-dispersed CNFs. The mechanism for enhanced mechanical properties of BSPN is also proposed using FT-IR spectroscopy. |
