Abstract:

The deposition and characterization of Langmuir-Blodgett (LB) layers of polyaniline (PAN) on solid supports is described. Langmuir films were spread as a mixt. of PAN and dodecylbenzenesulfonic acid (DBSA) at the water/air interface and deposited on either glass or indium tin oxide (ITO). Mono- and multi-layer films of PAN/DBSA were characterized by XPS, at. force microscopy (AFM), absorption spectroscopy and cyclic voltammetry (CV). The ultrathin films produced are highly uniform and very stable. Further characterization of the films was accomplished by scanning electrochem. microscopy (SECM) in the feedback mode. The cond. depended strongly on the pH of the soln. and the no. of layers deposited. Values for the pH-dependent lateral cond. of PAN LB films are reported. [on SciFinder(R)]
