TOMSK, Oct 5 – RIA Tomsk. Scientists of Tomsk State University (TSU) plan until the end of 2016 to 3D-print full-color displays for digital electronics which don't manufacture in Russia now; for their production they intend to use ink on the basis of organic semiconductors, the press service of the university reported on Wednesday.
Earlier it was reported that TSU scientists with colleagues from Tomsk State University of Control Systems and Radioelectronics work on technologies of 3D-printing of displays for electronics. TSU was succeeded to receive a grant for 18 million rubles from the Russian scientific fund for 2015-2017 on creation of ink on the basis of organic semiconductors.
"Now we are facing a difficult task – to create inks based on organic semiconductors, which are synthesized by chemists for us, and to develop technology of inkjet printing of devices of full-color displays", – quotes the press service the participant of the project Ruslan Gadirov.
It is specified that now the industrial release of printing electronics was mastered by South Korea, Japan and the USA. In Russia there is no such technology yet. TSU scientists mastered a contact way of drawing drops of ink via plotter printing several years ago. It requires not so high-quality inks for inkjet printing, but this technology has a serious drawback - the printing speed is extremely low.It is noted that for development of technology of an inkjet printing at the beginning of 2016 the necessary equipment, including the inkjet printer and devices for assessment of parameters of ink and the printer was purchased. Print speed on the new printer is higher, and the main technical difficulty was to obtain the same size drops.
It is added that as the basis for ink for inkjet printing it is planned to use the organic semiconductors synthesized for the Laboratory for Organic Electronics TSU by Institute of Problems of Chemical Physics RAS and Institute of Macromolecular Compounds RAS. To print the first samples of electronics researchers plan at the end of 2016.
