摘　　要：采用简单的、聚合物溶液或熔体浸润多孔阳极氧化铝(AAO)模板的方法,制备了不同结构的ABS纳米管及其阵列。对于溶液法,溶液的浓度会影响纳米管完整性:2.5%溶液制得的ABS纳米管管壁具有微孔缺陷;而5.0%溶液可以制得完整的纳米管。对于熔融法,熔体的温度影响了纳米管的结构:240℃和270℃都可以制得ABS纳米管,但其管壁和管长都不同。ABS纳米管的分解温度比本体ABS低100℃左右。The preparation of ABS nanotubes by using nanoporous AAO template through the physical wetting of polymer solution and melt is reported in this paper. The products with various structure are prepared. For the solution wetting method, the integrality of ABS nanotubes depends on the concentration of polymer solution. The concentration of 2.5 % makes ABS nanotubes have microporous walls; but 5 % can bring perfect walls. For the melt wetting method, the structure of products depends on temperature of polymer melting. The nanotubes can be prepared at 240 ℃ or 270 ℃, respectively with different length and wall thickness.The ABS nanotubes have a lower thermal decomposition temperature 100℃ lower than its bulk polymer.
