The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RÉSUMÉ

The present paper describes the possibility of formation of a double-layer superhydrophobic coating on a porous substrate from an active gas phase formed via electron-beam dispersion of polymers. A poly(ethylene terephthalate) track-etched membrane with a pore diameter of 250 nm was used as a porous substrate. An ultra-high molecular weight polyethylene was used for deposition as a target material to form the first hydrophobic layer on the membrane surface, and polytetrafluoroethylene was used for deposition as a target to form the second superhydrophobic layer. It is shown that the electron-beam deposition of the ultra-high molecular weight polyethylene layer leads to substantial hydrophobization of the membrane surface. The water contact angle of this layer changes from 92° to 125°, depending on its thickness. This change is due to the development of roughness of the deposited layer having hydrophobic properties with increase in its thickness. It is found that the electron-beam deposition of the polytetrafluoroethylene as a second thin layer results in formation of coating having superhydrophobic properties with water contact angle of 150°–160°. A significant increase in the contact angle is due to the lower free surface energy and more considerable development of the roughness of the fluoropolymer compared with the ultra-high molecular weight polyethylene coating.
