“…XPS tests have shown that there are various oxygencontaining and nitrogen-containing groups in the LIG nearsurface layer (for details, see [18,25]). The presence of such groups makes the surface of the synthesized LIG film structures hydrophilic.…”

Laser-induced graphene (LIG) films were synthesized by line-by-line scanning of cw CO2 laser focused radiation on the surface of industrial polyimide film as a result of pyrolysis of its near-surface layer. The structure of the synthesized film material is shown to be heterogeneous in thickness by Raman spectroscopy. The results of the study of the effect of the laser power and the distance between the lines on the specific electrical capacitance c of the synthesized material in aqueous solution of sulfuric acid are presented. It is shown that modification of LIG with polypyrrole (PPy) allows to increase c up to 60 mF/cm2. PPy-modified LIG films were used to make a prototype of a flexible film microsupercapacitor with an area of 8 cm2, using a gel electrolyte based on sulfuric acid and polyvinyl alcohol, with a 230 mF capacitance. Keywords: laser-induced graphene, electric capacitance, polypyrrole, microsupercapacitor.

“…LIG can be used to reduce friction [21], to produce microsupercapacitors, electrocatalysts (see [22]) and various sensors, e.g. humidity sensors [11,23] and strain sensors [24], bolometers [25], various biosensors [26,27] as well as quick-response photodetectors [28] based on photon-drag effect [29,30].…”

“…В записанном спектре на кривой 1 также присутствует D ′ -полоса, связанная с процессом двойного резонансного рассеяния [39]. Эта полоса может свидетельствовать о дефектах в графеновых слоях, связанных, например, с атомами азота, наличие которых в ЛИГ подтверждается данными РФ-ЭС [25]. Разложение спектра на кривой 1 показывает, что I 2D /I G ∼ 0.…”

“…ЛИГ можно использовать для уменьшения трения [21], для изготовления микросуперконденсаторов, электрокатализаторов (см. обзор [22]) и различных сенсоров, например, датчиков влажности [11,23] и механического растяжения [24], болометров [25], разнообразных биосенсоров [26,27], а также быстродействующих фотоприемников [28], работающих на эффекте увлечения [29,30].…”
