Electrochemical Synthesis of Polyphenylene in a Centrifugal Field

Abstract

Polyphenylene (PP) was electrochemically synthesized from biphenyl under a centrifugal field (315 g) and Earth’s gravity (1 g). The polymerization rate of biphenyl (BP) was found to be increased by the applied gravitational force. PP films thus synthesized on electrodes with and without centrifugation also exhibited clear differences in their physical and chemical properties. In addition, morphological structure of the film was also affected by the centrifugal field. A mechanism for the electrochemical deposition of PP film under the centrifugal force has also been proposed.
