It was named after researchers from the St. Petersburg State Electrotechnical University (LETI) and the State Optical Institute. Vavilov succeeded in creating flexible “glass” from an organic polymer to create more durable and flexible displays in tablets, monitors, ATMs, navigation devices, digital watches and other electronic devices. LETI told socialbites.ca about this.
There is no such technology in Russia, today such materials are produced by only a few companies outside Russia. The development of domestic scientists can be used to introduce into production various types of electronics with displays or screens. Currently, scientists can produce films the size of a smartphone screen under laboratory conditions, but larger films can also be produced if necessary.
Any screen consists of several layers that provide certain functions of the device. As a rule, such a sandwich system has an electrically controlled liquid crystal (LC) layer, the effectiveness of which is ensured by the presence of a polarizer and a light analyzer.
Polarizers are responsible for image formation, brightness adjustment, glare reduction and some other functions. However, today most polarizing filters are made of inorganic materials (special glasses that are brittle and relatively thick, up to 1 cm). Due to these properties, it is difficult to make miniature images with increased strength. An alternative is polarizers made from organic thin films.
“We received the first flexible thin-film light polarizers modified with graphene oxide with a thickness of only 0.1 millimeters in Russia. The strength (microhardness) is increased by a factor of 2 compared to the pure polymer matrix used to create thin film polarizers. This was achieved thanks to the original technology for the production of polarizers from organic polymers, taking into account the modification during structuring with graphene oxide due to the unique properties of the latter.”, noted in an interview with socialbites.ca Professor of the Department “LETI” Photonics of the Petersburg Electrotechnical University, “Photophysics of Nanostructured Materials ” and named after the Head of the Department of Devices GOI SI Vavilova Natalia Vladimirovna Kamanina.
The results of a study of the properties of materials show that the created films are a completely ready-to-use polarizing filter for displays for any purpose. Now scientists are looking for potential industrial partners.
Previously on LETI was created Neural network to detect defects in the production of solar cells.
