Detection of phase transition of thin Langmuir–Blodgett film based on an electrical capacitance measurement
Abstract
Langmuir–Blodgett films (10 layers) of a double-chain ammonium amphiphile complexed with poly(styrenesulphonate) on a pair of platinum electrodes have been found to show phase transition in aqueous electrolyte solution, which was successfully detected electrochemically by measuring electrical capacitance under applied alternating current.
