摘要: We report on Langmuir-Blodgett (LB) films made with emeraldine salt polyaniline (PAni-ES) and organophilic montmorillonite clay mineral (OMt), where synergy between the components was reached to yield an enhanced performance in detecting trace levels of cadmium (Cd(2+)), lead (Pb(2+)) copper (Cu(2+)). Detection carried out using square wave anodic stripping (SWAS) voltammetry indium tin oxide (ITO) electrodes modified LB PAni-ES/OMt nanocomposite, whose data were compared those obtained coated neat PAni-ES OMt films. The nanocomposite may be attributed stabilizing ordering effect promoted by Langmuir films, which then led more homogeneous According X-ray diffraction data, stacking layers preserved therefore chains did not cause exfoliation. Instead, affected polaronic state as indicated UV-vis, Raman FTIR spectra, also consistent changes observed for Taken together these results do indicate that semiconducting polymers minerals combined enhancing electrical properties nanostructures sensing related applications.
