Abstract:
Current-voltage characteristics (CVC) of bilayer lipid membranes formed on the support (s-BLM) were measured in static mode as well as in cyclic one with the period 33 s. The new cut of the wire from stainless stell SS-10T served as the support. In the range of voltages -0.9-(+)0.9V the similarity of the CVC for s-BLM as well as for support- electrolyte border was observed. Static CVC for both objects satisfy the Tafel's equation with close parameters. If the voltage amplitudes were over 0.3 V, s-BLM specific capacitance approached the same value for the support-electrolyte border. Possible electrical models of s-BLM are discussed.
