通过复合醋酸纤维素（CA）纳米纤维（CA-NF）形成CA/PBS复合材料，聚丁二酸丁二醇酯（PBS）的机械性能得到显着增强。 PBS 作为其他广泛使用的聚烯烃（例如由石油制成的聚乙烯和聚丙烯）的替代材料具有巨大的潜力。 PBS 以其生物降解性而闻名，但 PBS 的机械性能不足以作为工业应用的商业产品。在本研究中，为了增强PBS的机械性能，选择由CA制成的纳米纤维作为PBS复合材料的增强材料。使用 20 wt% CA 溶液与丙酮/N,N-二甲基甲酰胺 (6/4 wt/wt) 通过静电纺丝成功合成了 CA-NF。然后通过混合对齐或非对齐（随机）CA-NF 来制造 CA/PBS 复合材料。使用旋转收集器以 430 m/min 的转速获得高度取向的 CA-NF。 CA/PBS复合材料的横截面显微照片表明，电纺CA-NF与PBS基质具有良好的相容性。通过拉伸试验研究了CA/PBS复合材料的机械性能。结果发现，具有排列CA-NF的复合材料的杨氏模量高于具有随机CA-NF的复合材料的杨氏模量。 (C) 2017 年 Wiley 期刊公司。
The mechanical properties of poly(butylene succinate) (PBS) were significantly enhanced by compounding celluloseacetate (CA) nanofibers (CA-NF) to form CA/PBS composites. PBS has a great potential as an alternative material to other widely-used polyolefins such as polyethylene and polypropylene made from petroleum. PBS is especially well-known for its biodegradability, but the mechanical property of PBS was not sufficient as a commercial product for industrial applications. In this study, in order to enhance the mechanical property of PBS, a nanofiber made of CA was selected as a reinforcing material for the PBS composite. CA-NF were successfully synthesized using the 20 wt % CA solution with acetone/N, N-dimethylformamide (6/4 wt/wt) by electrospinning. The CA/PBS composites were then fabricated by mixing aligned or non-aligned (random) CA-NF. The highly oriented CA-NF were obtained using a rotating collector at the rotating speed of 430 m/min. The cross-sectional micrographs of the CA/PBS composites indicated that the electrospun CA-NF had good compatibility with the PBS matrix. The mechanical properties of the CA/PBS composites were investigated by tensile testing. It was found that the Young's moduli of the composites with the aligned CA-NF were higher than those of the composites with the random CA-NF. (C) 2017 Wiley Periodicals, Inc.
