Abstract

Mesoporous dual layers of polyaniline (PANI) supported Cu ₂O films have been electrochemically deposited on the ITO glass substrate from Lyotropic Liquid Crystalline (LLC) template with Brij56 surfactant. Polarized optical microscopy (POM), low-angle and wide-angle X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV-visible absorption spectroscopy are utilized to characterize the structure of LLC phase templates and resulting films, and also the optical property of bilayered films. The band gap of mesostructure dual layers Cu ₂O/PANI is found to be 1.86eV.
