O processo de eletropolimerização do 3,4 diidroxibenzaldeído (3,4-DHB) sobre eletrodos de pasta de carbono foi estudado utilizando voltametria cíclica e deposição a potencial controlado. As características dos filmes eletropolimerizados foram altamente dependentes do pH, potencial anódico de inversão de varredura, velocidade de varredura, concentração de 3,4-DHB e número de ciclos usados durante o processo de formação. A estabilidade dos filmes foi determinada em tampão citrato/fosfato no mesmo pH usado durante o processo de eletropolimerização. Os melhores resultados foram obtidos utilizando-se voltametria cíclica nas seguintes condições de trabalho: pH 7,8; 0,25 mmol L-1 de 3,4-DHB; 10 mVs-1; 10 ciclos e 0,0 ≤ Eapl ≤ 0,25 V. ...
