Electroinitiated polymerization coatings through packed and fluidized bed electrodes

摘要

AbstractOur previous studies on electroinitiated polymerization for formation of coatings on metal surfaces have all been in stationary cell systems. The feasibility of using either a packed bed or a fluidized bed cell in electroinitiated polymerization is now demonstrated, the objective being to form polymeric coatings on metallic and metal‐coated nonmetallic particles. The metallic particles that have been used are aluminum and stainless steel and the monomer‐electrolyte system used is DAA‐sulfuric acid. A comparison of current densities under various cathode potentials for the packed and fluidized bed systems is presented. The coatings obtained are analyzed through IR to establish the polymer functional groups. Additionally, both elemental analyses and thermal neutron activation analyses have been carried out to establish the compositions of the polymer coa
