摘要
采用溶液浸润多孔阳极氧化铝模板(AAO)的方法,在孔径为200nm的AAO模板中制备功能聚合物聚乙烯咔唑(poly(vinyl carbazole),PVK)一维纳米结构。SEM和TEM测试结果表明,2.5%和3.5%(质量分数)的PVK溶液可制得纳米管,其外径约为200nm,管壁厚度分别为30与70nm;而5.0%与10.0%(质量分数)的PVK溶液可制得纳米线,其直径约为200nm。提出了溶液浸润模板法中的完全浸润体系和部分浸润体系以及临界浸润浓度Cw。
The one-dimension nanostruetures were prepared by wetting anodie aluminum oxide （AAO） template with 200nm pores with a solution of functional polymer poly（vinyl earbazole） （PVK）. The results of SEM and TEM show that PVK nanotubes can be prepared by using the 2.5wt% and 3.5wt% PVK solution,the external diameter of which is about 200nm,the wall thickness is 30 and 70nm respectively; PVK nanowires can be prepared by the 5.0wt% and 10.0wt% PVK solutions,the diameter of which is about 200nm. The complete wetting regime and partial wetting regime in solution wetting template method and the critical wetting concentration are proposed.
