We investigated a physical properties for Langmuir-Blodgett (LB) films of sphingomyelin and polyamic acid(1:2 molar ratio) mixture. The LB ultra-thin films of mixture was deposited by the LB method on the indium tin oxide(ITO) glass. The electrochemical properties measured by cyclic voltammetry with three-electrode system in KClO4 solution. The current of reduction and oxidation range was measured from 1650 mV to -1350 mV, continuously. The scan rates were 50, 100, 150, 200 and 250 mV/s, respectively. As a result, LB monolayer films of sphingomyelin and polyamic acid mixture was appeared on irreversible process caused by the reduction current from the cyclic voltammogram. Diffusion coefficient (D) in the sphingomyelin and polyamic acid mixture was calculated 1.425 cm2s-1×106 at 0.1 N KClO4 solutions. |
