摘要:
首先采用异佛尔酮二异氰酸酯对氧化石墨烯（GO）进行改性，通过红外光谱证明GO成功接枝异氰酸根；然后采用原位聚合的方法使聚四亚甲基醚二醇1000（PTMG 1000）与改性GO（IGO）上的异氰酸根反应，再与二苯基亚甲基二异氰酸酯（MDI）进行预聚，制备了IGO@热塑性聚氨酯弹性体（TPU）纳米复合材料（IGO@TPU）。同时作为对比，在MDI和PTMG 1000预聚时加入GO，采用溶液共混法制备了GO/TPU复合材料。结果表明，IGO@TPU比GO/TPU和纯TPU有更好的力学性能，IGO@TPU的拉伸强度和扯断伸长率分别为36 MPa和570%，相较于纯TPU分别提升了338%和70.6%，相较于GO/TPU分别提升了188%和61.5%。
