Flexible electronics is most important trends in technology right now. The market is growing so fast that it’s expected to double in value within the next decade. Extremely light and even bendable optoelectronic tools that provide, detects and controls light will develop into commonplace in the close to future. Quite a lot of research is progressing in this direction, as exemplified by a paper just lately revealed in Scientific Reports.
The paper describes experimental and theoretical research performed by Brazilian and Italian researchers to reinforce the visual and electronic properties of polythiophene, an electrically conductive and electroluminescent polymer. Organic, light, flexible and simple to course of, it’s extremely attractive in mechanical terms.
“The configuration of polythiophene processed in the most typical way, by spin casting, is so disordered as to impair its optical and electronic performance. In our research, we got down to sample the material in a more ordered method and make it more selective in emitting and absorbing light,” stated Marilia Junqueira Caldas, a full professor on the University of São Paulo’s Physics Institute (IF-USP) in Brazil. Caldas participated in the research by contributing to the theoretical framework that described and defined the experimental data.
The pattern she talked about was obtained by way of a surprisingly simple stacking arrangement. A droplet of the polymer in solution was deposited on a substrate. As it evaporated, an elastomeric stamp was positioned on it to provide a sequence of parallel stripes, which organized the interior structure of the material.
This system organized the intrinsically disordered materials throughout the strategy of “growth,” and as such, it may be utilized in a variety of optoelectronic functions.”Our method demonstrates a viable technique to direct optical properties by means of structural management, and the noticed optical achieve opens up the opportunity of using polythiophene nanostructures as building blocks for organic optical amplifiers and active photonic devices,” the authors write in the article.
