摘　　要：以孔径为200 nm的阳极氧化铝(AAO)为模板,用简单的物理方法制备了生物可降解聚合物聚己内酯(PCL)的蚋米管、线及其阵列结构。SEM和TEM测试结果表明:熔融法在120℃和140℃都能制得整齐的纳米管阵列结构,管径均匀,约300nm。在溶液法中,5%浓度的溶液制得了杂乱的纳米管,而10%浓度的溶液制得的是纳米线阵列,直径在200nm左右。Biodegradable polycaprolactone （PCL） nanotubes and nanowires with array structure are prepared by a simple physical method using anodoic aluminum oxide with the pore diameter of 200nm as template. The results of SEM and TEM illuminated that nanotubes with array structure can be obtained by polymer melt-wetting method both at 120℃ and 140℃. The outer diameter of nanotubes is uniform, about 300nm. The random nanotubes are prepared by 5.0wt% polymer solutions, but good nanowires with array structure can be prepared by 10.0wt% polymer solutions, and the diameter of nanowires is about 200nm.
