摘要 采用聚合物溶液和熔体浸润多孔阳极氧化铝(AAO)模板的物理方法,成功制备了通孔的热塑性聚氨酯(TPU)纳米管及其阵列结构.扫描电子显微镜(SEM)和透射电子显微镜(TEM)测试表明:有效地调整溶液滴加量可制备出不同结构的聚合物纳米管阵列.以浓度为7.0%(wt)TPU溶液为例,研究了溶液滴加量对纳米管结构之间的关系,2μL为制得TPU纳米管阵列结构的最佳滴加量.并探索首次浸润程度对纳米管结构的影响,完善了模板浸润法的多次浸润机理. Thermal polyurethane （TPU） nanotubes and the array structure were prepared by wetting porous anodic aluminum oxide（AAO） template with polymer solution and melt. Scanning electron microscopy （SEM） and transmission electron microscopy （TEM） results indicate that nanotubes structures depend on the solution addition. Different array structures of nanotubes were obtained using the 7.0 % （wt） TPU solution addition of 1 μL, 2 μL and 3 μL, respectively. And 2 μL proves to be the optimal solution addition. The effect of the degree of first wetting on nanotubes structure was studied to support the multi-time wetting mechanism for polymer solution wetting method.
