dc.description.abstract Vliv binárních elektrolytů, různých tenzidů na povrchové napětí roztoků derivátů celulozy při teplotě 25 deg C byly studovány vzhledem k možnosti depozice tenkých vrstev těchto polymerů na tuhé povrchy. cs
dc.description.abstract The influence of binary electrolytes (sodium floride, potassium bromide, lithium iodide), and different tenzides (sodium lautylsulphate, cetylpyridiumbromide) on the surface tension of cellulose solutions at constant temperature 25 degrees C has been studied and the suitability of the systems for thin layer deposition on solid polymer surface with specific respect to utilization of these compounds as a part of handling means of final arrangement has been testified. The cellulose ethers studied were two types of hydroxyethylcellulose, carboxymethyl cellulose and methylcellulose. The surface tension was determined by Wilhelm's tensometric method for solutions. It has been found that generally a small addition of binary electrolytes slightly increases the surface tension, whereas the same amount of tensides remarkably decreases the same property of examined cellulose derivatives. Some self-organizing ability of the studied cellulose derivatives has been recognized to form specific structures in the liquid surface connected with gaseous surroundings. en
