    We studied electrochemical characteristics of LB films by using cyclic voltammetry with a three-electrode system, An Ag/AgCl as a reference electrode, a platinum wire as a counter electrode and Langmuir-Blodgett(LB) film-coated Indium tin oxide(ITO) as a working electrode were used to studing electrochemical characteristics at a various concentration of NaClO4 solution. A measuring range was reduced from initial potential to -1350 mV, continuously oxidized to 1650mV and measured to the initial point. The scan rate was 100mV/s. The monolayer surface of the LB film have been measured by Atomic Force Microscope(AFM). As a result, We comfirmed that the microscopic properties of LB film by AFM showed the good orientation of momolayer molecules and the thickness of monolayer was 3.5-4.1nm. The cyclic voltammograms(CV) of the ITO-coated glass observed the peak potentials for the reduction-oxidation reation. LB films of 4-octyl-4'-(5-carboxy-pentamethyleneoxy)azobenzene (8A5H) / L-α-phosphayidylcholine, dilauroyl(DLPC) appeared irreversible process caused by only the oxidation current from the cyclic voltammogram. The current of oxidatation increased at cyclic voltammogram by increasing 8A5H density in LB films. The diffusivity(D) of LB films increased with increasing of a 8A5H amount and was inversely proportional in concentration.
