| 中文摘要: |
| 用溶液铸膜工艺制备了纤维素 / 聚碳酸亚丙酯多元醇共混膜,以扫描电子显微镜、电子拉力机、差示量热扫描仪、透气透湿仪等试验仪器对共混膜进行了表征和性能测试。 研究表明:纤维素 / 聚碳酸亚丙酯多元醇共混膜的力学性能和透湿性能随聚碳酸亚丙酯多元醇含量的提高而提高,而透气性能则相反。 共混膜中聚碳酸亚丙酯多元醇含量为 30% 时共混膜的力学性能最好,共混膜中聚碳酸亚丙酯多元醇含量为 40% 时透湿性能最好,透气性能最差。 |
| 英文摘要: |
| Cellulose / PPC blend Films were prepared by solution casting process. The performance of the blend films were characterized by DSC, SEM, mechanical tester, and air permeability tester. The results indicated that the mechanical properties and the moisture permeability of cellulose / PPC film increase with the contents of PPC while the air permeability decrease; the mechanical performance of the blend film is the best when the PPC is 30% . When the content of PPC is 40% , the wet permeability is the highest while the air permeability is the lowest. |
