Estudo do efeito dos parâmetros de síntese na condutividade elétrica do compósito fluoreto de polivinilideno / polianilinaStudy of the effect of synthesis parameters in the electrical conductivity of the composite poly (vinylidene fluoride) / polyaniline ABSTRACTThe electroactive polymers have been the subject of many studies in the last decade, mainly because its unique properties. They are used in composite structures, which allow its application in many fields, as for example, sensors and artificial muscles. The electrical properties of these composites are influenced by the doping state of the electroactive polymer, which is controlled during its synthesis process. Therefore, this work aimed to evaluate how the synthesis parameters influence the electrical conductivity of the composite PANI/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 and the solvent DMF. To evaluate possible changes in the chemical structure of the composite, the samples were submitted to FT-IR and XRD analysis. It was possible to conclude that the parameters relative to the production of PANI directly influence in the electrical conductivity of the composite. So, the sample produced with major quantities of monomer, initiator and dopant were statistically significant to increase the electrical property of the composite.

“…It is well known that polymers are widely used in many areas due to its excellent mechanical properties, good chemical resistance to severe environmental stress and versatility in fabrication for a variety of forms. Among various polymers, polyvinylidene difluoride (PVDF), 10 which is the best known ferroelectric polymer and exhibits the highest pyroelectric coefficient (p ¼ 24-27 C/m 2 K) among the ferroelectric polymers, 11 is selected as the polymer matrix for the composites in this work. Poling is critical for a ferroelectric material to exhibit its pyroelectric effect.…”

Pyroelectric composites of triglycine sulfate (TGS)-polyvinylidene difluoride (PVDF) doped with graphene are studied. It is found that the graphene can effectively improve the polling efficiency and thermal property of the composites so that the infrared detective performance can be significantly improved. For example, by adding about 0.83 wt.% of graphene, the infrared detective property can be improved by more than 30%. It is also found that the size of the graphene plays a critical role on the property improvement. For example, the small-sized graphene prepared by ultrasonic exfoliation (UE) method is more effective than the big-sized graphene prepared by electrochemical exfoliation (EE) method.
