Abstract :
Four-layer Langmuir-Blodgett films of phosphatidic acid (polar) and stearic acid (non polar) have been prepared on glass substrates with aluminium electrodes. Dielectric measurements over the frequency range 5 Hz to 13 MHz showed plasticisation and DC conductivity effects when the films were exposed to changes in relative humidity
