摘要
研究了一种拟用于SPR生物传感器的聚吡咯衍生物的制备工艺。以丙烯酰氯和吡咯钾盐合成丙烯酰吡咯,然后以偶氮二异丁腈(AIBN)为引发剂,通过自由基聚合为聚丙烯酰吡咯(PAP);将PAP溶于N,N-二甲基甲酰胺(DMF),然后将其旋涂到金膜上形成涂膜表面;最后涂膜表面与吡咯在三氯化铁溶液中进行化学法聚合,形成聚合吡咯层。结果表明,聚合膜的厚度随着时间的延长和单体浓度的增加而变厚。
The preparation process of polypyrrole derivatives for the SPR biosensor is studied. Acryloyl pyrrole is synthesized from aeryloyl chloride and pyrrole potassium salt, and then PP-pyrrole （PAP） is synthesized with azo-bisisobutyronitrile （MBN） as the initiator by the radical polymerization, and dissolved in N, N＇-dimethylformamide （DMF） before coated on the surface of gold film. Finally the coated surface is polymerized with pyrrole in the chemical ferric chloride solution to form pyrrole polymer layer. The results show that the thickness of the polymer membrane is thickening with the time and the increase of monomer＇ s concentration.
