The research team from Purdue University in the United States has developed a new type of conductive glassy transparent polymer film material, which is easy to manufacture on a large scale, the cost is lower than that of indium tin oxide film, and the conductivity is better than that of ordinary polymer.
In materials science, transparency and conductivity are inconvenient. Traditional glass as an extremely transparent material is an insulator, and touch screens of smart phones usually increase the indium tin oxide thin film coating to achieve conductivity. Although the cost of polymer preparation is low, However, in order to make them conductive, a chemical doping process is usually used, which increases the manufacturing cost and also reduces the transparency of the material. The research team of Purdue University obtained a radical modification of the transparent non-conductive polymer material. New polymer film material.
According to Bryan Boudouris, one of the authors of the paper, 'our idea is whether we can make polymers that can be produced on a large scale and at the same time make them electronically active. The precursors of new materials can be produced in tons and obtained from carbon-based materials. The result of a conductive transparent material is amazing.
The key to the success of the transparent material's conductivity is the radical groups. The team started the computer simulation with the addition of a partially transparent radical group. Through a number of simulation teams, the desired free radical group that can make the polymer conductive was obtained. The team designed the process for preparing this new material at room temperature based on the simulation results, and successfully obtained a new type of conductive glassy transparent polymer film material. The research results were published in the journal Science.
