Desenvolvimento de tinta condutiva a base de carbono (negro de fumo) para impressão de trilha elétrica

Abstract

In this work, it was developed a paint capable of conducting carbon-based electrons of carbon black type. Such development allows the electronic industry field with a new vision to the called disposable electronic, RFID tags, printed circuits on disposable substrates and biosensors are the most benefited fields with the developed formulation. For such, it was made an organic electronics, electrochemical, electrical conductivity and resistance, Ohm's law adapting to the proposed situation, PCB construction techniques and chemical reaction concepts deepening. In choosing formulation reagents, it was aimed the usage of easy access, low cost and skin harmless as final product materials, in order to allow future application and development of wearable devices, field with investment potential by entrepreneurial and scientific societies. As a result, the formulation with surfactants showed good grip, as well as voltammetry and resistance analysis yielded balance in the electron transference through the paint.
