SILVA, Rodrigo Amorim Bezerra da et al. Development, characterization and electroanalytical application of a fluid composite made of epoxy adhesive, graphite, and ciclohexanone. Quím. Nova [online]. 2010, vol.33, n.6, pp.1398-1402. ISSN 0100-4042.

A fluid conducting composite material prepared from graphite powder, commercial epoxy resin Araldite®, and cyclohexanone has been developed. The composition was optimized considering the mechanical properties as conductivity and adhesiveness using response surface methodology. This work employed cyclic voltammetry and amperometry to investigate the characteristics of such composite electrodes without and with the insertion of Prussian blue in the electrode body (bulk modified electrode). The composite electrodes were also successfully used for the amperometric detection of hydrogen peroxide at 0.0V vs Ag/AgCl.

Keywords : fluid graphite-epoxy composite; alternative fabrication method; Prussian blue modified electrode.
