Electrochemical Investigations Of The Functionalization Of Carbon Nanotube Modified Electrode And Liquid/Liquid Interface

Nano materials is new materials field which developed at the beginning of 1980s.Nano materials have many particular properties and they may have important application in many fields.The found of carbon nanotubes is the highly representative new breakthrough to the field of materials science , and at first,it was the focus of physics,chemistry and materials science.Electrochemistry is one of the novel areas in life sciences.In the research field of life sciences,modern elelctroanalylitcal chemistry technology not only could detect the content of various biologic substances but also the electrochemistry information of life process.This dissertation consists the following four parts:The first part gave a general introduction of the quality and application of carbon nanotubes ,;development research of the liquid/liquid interface; the quality and application in liquid/liquid interface of PAMAM and zeolite.The second chapter the carbon nanotubes skived to room temperature ion liquid ,then formed nanotubes/ ion liquid sol at room temperature. The carbon nanotubes/ion liquid sol electrode revealed a stable and sensitive electrochemical response to the reduction of nitrobeneze.The third part used the amidocyanogen of PAMAM and the carboxyl of the function carbon nanotubes formed MWCNTs/PAMAM to modification liquid/liquid interface.At W/DCE,W/NB interface formed self-assembly film.FIRT and UV spectrum to show the exist respectively.The final paper in this dissertation, the modification of the water/1,2-dichloroethane interface with a new typeβzeolite membrane is studied. It is hoped to extend this study to investigate the diffusion of ions within the zeolite pores with electrochemical methods, and to apply these properties to size selective sensors.
