摘要
Films of anodic aluminum oxide, prepared in an aqueous solution of 0.4 M tartaric acid, are studied by means of electron paramagnetic resonance (EPR) before and after heating at 200–700°C. The presence of a carbon radical is established in the films (g factor, 2.0027 ± 0.0002). The nature and conditions of its formation during the electrochemical oxidation of aluminum and the heat-treating of anodic aluminum oxide films are discussed.
