摘要 采用溶液共混浇注成膜法制备氧化石墨烯/热塑性聚氨酯(TPU)复合材料,并对其结构和性能进行研究。结果表明:氧化石墨烯在TPU基体材料中分散较好;随着氧化石墨烯用量(0~5份)的增大,氧化石墨烯/TPU复合材料的拉伸强度增大,拉断伸长率未明显下降;当相同用量(均为1份)的氧化石墨烯、碳纳米管、石墨和炭黑分别填充TPU时,氧化石墨烯/TPU复合材料物理性能提高幅度最大,补强性能最好。 The graphene oxide/thermoplastic polyurethane(TPU) composites were prepared by solution blending and casting film method, and their structure and properties were investigated. The results showed that,graphene oxide was well dispersed in the TPU matrix. As the addition level(within 0-5 phr) of graphene oxide increased, the tensile strength of graphene oxide/TPU composites in- creased,and the elongation at break didn't have any obvious decrease. Compared with carbon nano- tube,graphite or carbon black,when the addition level of filler was 1 phr, the TPU composites filled with grapheme oxide showed better physical properties.
