[求助] 碳纳米管修饰电极已有1人参与

大家做碳纳米管修饰电极是怎样将碳管分散液修饰上去的,现在有什么好的新方法啊,我用滴涂法充电电流很大,而且容易脱落,求助下做过的亲们交流一下啊,先谢谢了!

w我们实验是的先酸化,接上羧基之后在修饰在电极上。我和你说一下我之前看的一篇文献吧,你参考一下。Prior to use, the surface of GCE was polished carefully to a mirror-finished with slurry alumina (0.05 μm) at polishing cloth for 2 min. Then, the electrode was rinsed with distilled water and cleaned ultrasonically into a mixture of water:methanol (1:1) for 3 min to remove particles that might be trapped at the surface. A 5.0 mg of f-MWCNTs were added into 2.5 mL DMF and f-MWCNTs were dispersed by ultrasonic treatment for 6 min. Then, 3.0 μL of the dispersed mixture was poured on the GCE surface and allowed to evaporate solvent and formed f-MWCNTs on the electrode surface.

嗯,好的,谢谢,能发一下文献名吗,我的做法差不多,但是充电电流很大,不知道怎样降低

文献没带回来,下次告诉你吧。那是个分子印记的传感器文献
