1. Eletrodo compósito à base de grafite-Araldite®: aplicações didáticas - parte II
This work proposes the use of a graphite-Araldite® 70% (graphite, m/m) composite electrode in didactic experiments, specifically in the quantitative determination of the neurotransmitter dopamine (DA) in a sample of pharmaceutical formulation. The goal is to demonstrate the possibility of using voltammetric techniques in quality control of medicines, beside

2. Desenvolvimento, caracterização e aplicação eletroanalítica de um compósito fluido de adesivo epóxi, grafite e ciclo-hexanona
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 characte

4. Eletrodo compósito à base de grafite-araldite®: aplicações didáticas
A composite electrode prepared by mixing a commercial epoxy resin Araldite® and graphite powder is proposed to be used in didactic experiments. The electrode is prepared by the students and applied in simple experiments to demonstrate the effect of the composite composition on the conductivity and the voltammetric response of the resulting electrode, as wel

5. Development of graphite-polymer composites as electrode materials
Graphite powder was mixed to polyurethane, silicon rubber and Araldite® (epoxy) in order to prepare composite materials to be used in the preparation of electrodes. Results showed that voltammetric response could be obtained when at least 50% of graphite (w.w-1) is present in the material. SEM and thermogravimetry were also used in the characterization of t
