The research teams of Professor O. E. Glukhova and Professor A. N. Nasibulin, who heads the Laboratory of Nanomaterials at the SKOLKOVO Institute of science and technology (Skoltech), proposed a universal material based on transparent, highly conductive and tensile films of single-wall carbon nanotubes (CNTS) deposited on a substrate of polydimethylsiloxane (PDMS). Depending on the method of manufacturing, this material can demonstrate both high sensitivity of electrophysical characteristics to mechanical deformation and maintain the stability of the parameters during deformation. Such a variety in the behavior of the material characteristics is achieved by two methods of manufacturing using dry transfer technology: the application of films from the CCNT to the prepared PDMS substrate and the application of films from the CCNT to the pre-stretched surface of the PDMS. A series of numerical experiments performed by the research team of Professor O. E. Deaf, allowed to establish a new effect, which is to increase the resistance of the created material on the basis of hybrid structures of SWNT/PDMS from 0.4 kOhm to 4.8 ohms with a cycle of tensile strain from 0 to 100%, which was confirmed during field tests. The created material can be used in devices of medical wearable electronics as a material for creation of high-tensile electrodes.
The original results were presented by the research teams of the SSU and Skoltech in the article "Mechanically Tunable Single-Walled Carbon Nanotube Films as a Universal Material for Transparent and Stretchable Electronics", published in the high-rating journal of the American chemical society (ACS) ACS Applied Materials & Interfaces. The journal has an impact factor of 8.456 and is included in the first quartile on the Web of Science Core Collection and Scopus databases. The scope of scientific interests of the journal includes the practical application of new materials with unique properties in advanced industries.
