제목 Two-steps process preparation of polybutylene succinate film reinforced by pure cellulose nanofibril and lignocellulose nanofibril with different lignin content
초록 In this study, polybutylene succinate (PBS) films reinforced by pure cellulose nanofibril (PCNF) and lignocellulose nanofibril (LCNF) were prepared. For film formations, a two-step process, dispersing in solvent and twin-screw extruding, was used. PBS/PCNF ratio was variated into 90/10, 95/5, 97/3, and 99/1. PBS was dissolved into 1.5% CNF in NMP suspension at 65℃ for 4 h. After oven-drying at 65℃ for 24h, It was subjected to a twin-screw extruder at 155℃ with rotational speed of 90 rpm. Compared to directly subjected solids form of PBS and CNF filler to twin-screw extruders, this two-steps process offered improved mechanical properties. Further, the effect of lignin content in film properties was also studied by using LCNF with lignin content variated in 3, 15, and 30%.
