“…The optimal graphite proportion for electroanalytical applications is related to the mass ratios and volume fraction for the type of carbon and epoxy used. It is associated with the conductivity and minimal double layer capacitance of the composite [14,15]. This ratio gives comparable conducting fraction to that found by Vicente et al [14].…”

“…It is associated with the conductivity and minimal double layer capacitance of the composite [14,15]. This ratio gives comparable conducting fraction to that found by Vicente et al [14]. The oxidase enzyme was mixed with 2% poly(ethylenimine) (PEI), which acts as the enzyme stabilizer [16].…”

“…This effect is explained by so called percolation theory [120,121,143,144], e.g., resistance of graphite electrode containing 35% of graphite amounted to 30 W [145] or only 15% of silver addition to Kel/F is sufficient for achievement of about 98% conductivity of pure silver [120]. In an ideal case, such electrodes can represent array of microelectrodes.…”

“…Segundo Trijueque et al, 13,14 com base na teoria de percolação, os melhores resultados de condutividade em compósitos de grafite são obtidos com 62% do condutor. As partículas de grafite atuariam como um arranjo de microeletrodos, cada uma delas contribuindo para a condução da corrente, o que explicaria os melhores resultados no caso do compósito contendo 70% de grafite.…”
