Preparation of Clay Hybrid Films by the LB Method and Their Application to an Electrode Modifier

摘要

Organized organic-inorganic ultrathin films have been constructed from the fabrication of smectite unit layers and an amphiphilic ruthenium (II) complex monolayer using the Langmuir-Blodgett (LB) technique. According to the method, a chloroform solution of an amphiphilic ruthenium (II) complex is spread onto an aqueous subphase containing exfoliated clay suspension. A composite film of a Ru (II) complex and a clay particle thus formed is transferred onto a hydrophilic glass plate by the vertical dipping method. The surface structure of a deposited film was studied with an atomic force microscope (AFM). The applications of such a hybrid film to electrode modifiers have been described.
