Abstract

e-spinning process is determined by solution's parameters such as concentration, viscosity, surface tension, resistivity and etc. These parameters make different influence on intensity of spinning process. But it is unknown which solution's feature is more or less important to obtain the maximum spinning intensity. In this work we discuss a problem, how to build a criteria, by which will be possible to determine the solution's spinning intensity from its parameters without spinning it. A proposed formula coincidence with experimental data and therefore it is possible to predict spinning intensity from solution's parameters. [ABSTRACT FROM AUTHOR]

Abstract

The aim of this investigation was to determine the role of negative direct current and alternating current (plasma) corona treatments in modification of bio-based dispersion barrier coatings and the response of replacing fossil-based binder with a thermoplastic bio-based binder (starch). The study emphasizes the importance of understanding and optimizing electric corona discharge in order to obtain high oxidation level without harming the substrate and causing unintentional treatment of the reverse side. The coatings were exposed to different corona treatment conditions using a novel developed sheet-fed laboratory-scale device. Corona-induced topographical, mechanical and surface chemical changes were observed from atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), and contact angle and surface energy measurements. XPS results indicated further that partial starch decomposition occurred after plasma treatment. Coated surfaces became substantially smoother after both treatments suggesting that nanoparticle migration and re-orientation effects occurred. Additionally, reverse side effects and strike through were also discussed., (Copyright © 2018 Elsevier Ltd. All rights reserved.)
