摘要: Publisher Summary The chapter focuses on electrodes that are chemically modified. Chemically modified electrode can be defined as a conducting or semiconducting material has been coated with monomolecular, multi-molecular, ionic, polymeric film. It also helps to alter the electrochemical, optical, and other properties of interface. conductive semiconductive substrates derived from conventional materials, while adlayers widely diverse in their origins properties. This diversity enhances range scope electrochemical techniques. an adlayer impart predictable function electrode. substrate is platform supports adlayer. Available custom fabricated used commercially. In most preparation schemes, surface treated before modification provide reproducible attributes. These procedures involve treatments, adaptations additions where needed. After desired composition like single- multi-component achieved, lateral pressure applied increase two-dimensional film concentration. attractive forces sufficient exclude solvent molecules interface between solid support
