Resumo

Recently, the use of piezoelectric materials in energy generation has been drawing attention for contributing with several technological advances in the engineering and development of sensors. Piezoelectric polymer sensors and actuators offer the advantage of processing flexibility as they are lightweight, hard, easily fabricated over large areas, and can be cut and formed into complex shapes. Among the polymers and fullerenes used in piezoelectric devices, poly (vinylidene fluoride) (PVDF) and phenyl-C61-butyric acid methyl ester (PC61BM) stand out. Both are used as electron acceptor units in PVDF/PCBM films to increase the output performance of piezoelectric nanogenerators. PVDF exhibits a polymorphism, transforming into various crystalline forms under certain conditions. Its piezoelectric properties are superior compared to other types of polymeric materials due to its polarity and crystal structure. In nature, the PVDF polymer consists of at least five different structural forms. Thermodynamically, the most stable phase at room temperature and pressure is the a phase. At high mechanical strain, ß-phase PVDF is thermodynamically more stable than a-PVDF. Another fact is that the ß-PVDF phase is responsible for most of the piezoelectric responses due to its polar structure with orientation. Regarding the organic acceptor materials used in the area, phenyl-C61-butyric acid methyl ester fullerene (PC61BM) has interesting characteristics in this application, such as its strong electron affinity and high electron mobility. The use of materials based on fullerenes in research and applications is very relevant in the current context and examples are plastic solar cells, molecular electronics and nanomachines, artificial photosynthesis, among others. Among the techniques used to manufacture the films, drop-casting was prioritized. The technique has technological relevance for its simplicity and has interesting applications such as in the manufacture of photovoltaic cells and biosensors. The samples were tested together with the construction of a piezoelectric device in order to contribute to the area of materials and improvement of technologies that employ thin films containing materials of interest in the area of energy generation.
