Estudo do efeito dos parâmetros de síntese na condutividade elétrica do compósito fluoreto de polivinilideno / polianilina

The electroactive polymers have been the subject of many studies in the last decade, mainly because itsunique properties. They are used in composite structures, which allow its application in many fields, as forexample, sensors and artificial muscles. The electrical properties of these composites are influenced by thedoping state of the electroactive polymer, which is controlled during its synthesis process. Therefore, thiswork aimed to evaluate how the synthesis parameters influence the electrical conductivity of the compositePANI/PVDF.The synthesis parameters evaluated were the concentrations of monomer, initiator and dopant,and the synthesis time. PANI was obtained by chemical polymerization in a solution containing PVDF andthe solvent DMF. To evaluate possible changes in the chemical structure of the composite, the samples weresubmitted to FT-IR and XRD analysis. It was possible to conclude that the parameters relative to the productionof PANI directly influence in the electrical conductivity of the composite. So, the sample produced withmajor quantities of monomer, initiator and dopant were statistically significant to increase the electrical propertyof the composite
