In order to alleviate environmental pollutions caused by the use of ruthless disposable plastics, many studies on biodegradable plastics have been conducted. However, it is difficult to commercialize biodegradable plastics due to poor mechanical properties. In this study, we fabricated nanocomposite fibers of poly(butylene adipate-co-terephthalate) (PBAT) and cellulose nanocrystal (CNC). Using dimethyl sulfoxide (DMSO) as a solvent, PBAT/CNC solutions were made by solution blending. PBAT and CNC were dissolved or dispersed in DMSO and each solution was blended at 100 °C for 1 day. The contents of CNC compared to PBAT were 0, 1 and 2 wt%. PBAT/CNC 0, 1, and 2 wt% fibers were fabricated by dry-jet wet spinning and their total draw ratio (TDR) was 9, 12, and 15 each of the contents. As increase the contents of CNC, mechanical properties were reinforced. |
