聚多巴胺(PDA)涂层是一种天然聚合物，由于其在几乎所有类型的基材表面都具有高的附着力和稳定性，在许多领域引起了极大的关注。本工作首次将PDA涂层作为毛细管气相色谱(GC)的柱前处理方法，并将其应用于瓜环(CB7)固定相柱的制备。制备的PDA-CB7色谱柱表现出弱极性，在GC中分离某些关键分析物质方面优于未制备PDA的CB7色谱柱。这项工作展示了PDA作为一种简便的毛细管气相色谱柱前处理方法的优势和潜力。(三)中国医学科学院中国化学会、药物所2015年。爱思唯尔出版，版权所有。
Polydopamine (PDA) coating, a nature-inspired polymer, has attracted great attention in many areas due to its high adhesion strength and stability on almost all types of substrate surfaces. This work presents the first example of using PDA coating as a column pretreatment method in capillary gas chromatography (GC) and its employment in the column fabrication of cucurbit[7]uril (CB7) stationary phase. The fabricated PDA-CB7 column exhibited weakly polar nature and had advantages over CB7 column without PDA for the separations of some critical analytes in GC. This work demonstrates the advantage and potential of using PDA as a facile column pretreatment method in capillary GC column fabrication.
