Abstract

3D printing is an additive manufacturing technique where it is possible to print objects in three dimensions with details and adequate precision. 3D printing technology has brought great advances in science. The decentralization of the production process allows the design and manufacture of unique pieces ranging from biomedical applications, aircraft parts, functional devices to printed electrodes. Given this scenario and the importance of this technology, we can observe a significant increase in the number of publications and applications in 3D printing. And its use in chemistry has been gaining a lot of space in current science because it allows rapid and specific prototyping. Thus, chemists are finding countless applications, where we can highlight the work in the construction of microfluidic devices, complex parts, equipment, storage and energy conversion devices, accessories for hyphenation of techniques, conductive printed electrodes, and so on. In this project, our goal is the development of conductive filaments and transparent conductive filaments for use in 3D printing and electrocatalytic applications. Our goal is to produce our own conductive filaments because it is a way, we can know exactly their composition. This allows a total control over modifications and allows us a better planning of the applications of these filaments as printed electrodes. In addition, we intend to compare our new filaments with commercial filaments, and we will start to develop new filaments for printing transparent 3D electrodes. Consequently, we will be able to modify filaments with additives/catalysts for electrocatalytic studies in proof of concept condition. We will do our best to produce significant advances in printed electrodes, contributing to the publication of high impact scientific articles and patents, when appropriate. Finally, we expect a high level of professional and academic development for the candidate Mateus Veras Pereira. (AU)
