Abstract

Printed and flexible electronics represent an emerging market that has been growing significantly in the last 10 years. According to the report "Flexible, Printed and Organic Electronics 2020-2030: Forecasts, Players & Opportunities", carried out by IDTechEX, the current market for printed electronics is estimated at US$41 billion and is expected to grow to more than US$ $74 billion by 2030 [1]. Most of these investments are made in the development of printable conductive and semiconductor inks, used in a wide range of applications, such as photovoltaics, electronic circuits, light-emitting diodes, among others [2-5]. The development of low-cost electronic devices through printing techniques, such as screen printing, spray-coating, drop-casting and roll-to-roll, has motivated studies on the electrical properties of electronic materials processed in the liquid route. One of the main challenges in this area of printed electronics is the manufacture of transparent electrodes, which are currently produced from transparent conducting oxides, TCO (Transparent Conducting Oxides), presenting greater cost and complexity for deposition. An alternative to replacing TCO is the formation of composites from organic and inorganic materials to manufacture transparent electrodes that can be processed via the liquid route and do not require the same laboratory structure, producing thicker films with the same properties as nanometric films. The discovery of the electrical properties of polymers exhibiting electrical conductivity in the late 1970s brought a new scenario, giving rise to the area of organic electronics. Thus, with the advancement of studies we have had a revolution in technology with the use of new materials. These conductive polymers and their characteristics are the subject of extensive study, with our group working on their properties and applications [6-8], through a partnership with the company TICON, with relevant and innovative results. The transparent conductive paint from the conductive polymer has application capacity mainly in the refrigeration and automotive industries, and can be expanded to other sectors, for example, as electrodes in optoelectronic devices and for application in glass in construction. Knowing that in the automotive industry there are already means of defogging windows, our product comes to improve this system, having several technical advantages, since the current system for defogging car front windows is done by air insufflation, therefore, all necessary a mechanical system to divert air to the glass resulting in increased weight of cars and greater consumption. With the application of our concept, the use of this system becomes unnecessary, resulting in reduced weight and consumption, due to the lack of need to use the car's air system to defog the glass.
