| 摘 要： | 采用溶液浇铸法制备纳米纤维素/聚乳酸/聚乙二醇三元复合材料,与纯聚乳酸相比,该复合材料的抗张强度和断裂伸长率分别提高了41.2%和38.4%.傅立叶红外(FT-IR)表明聚乙二醇的存在使纳米纤维素和聚乳酸之间形成了强烈的氢键作用,明显改善了纳米纤维素和聚乳酸之间的相容性,提高了界面黏结力.扫描电子显微镜(SEM)观察了...

| Abstract: | The casting solution was blended with poly(lactic acid)(PLA),polyethylene glycol(PEG) and cellulose whiskers.PEG was added to the matrix as compatibilizer to improve the compatibility between the hydrophobic PLA and the hydrophilic cellulose whiskers.The composites obtained by solvent casting methods from N,N-dimethylacetamide(DMAc) were characterized by tensile testing machine,scanning electron microscope(SEM),transmission electron microscopy(TEM) and Fourier transform infrared spectroscopy(FT-IR).The tens... |
