This technique examines the ingress behavior of \ud835\udc5b-octyltriethoxysilane and \ud835\udc56-butyltriethoxysilane and the properties of the resulting water-repellent layers.<\/p>\n<p>Remarkably, the study discovered that targeted blending and cross-linking of PEO- and PPO-based polyesters can create synergistic effects. A 1:1 blend of short-chain PPO and long-chain PEO exhibited a resistivity five times lower than pure PEO and three times lower than pure PPO. These effects are attributed to enhanced chain mobility and intrachain hopping mechanisms, which are amplified by the cross-linking process.<\/p>\n<p>Beyond improved ion conductivity, these networks offer rubber-like elasticity and high water tolerance, making them suitable for diverse applications, particularly under mechanical stress, in atmospheric conditions, or even in aqueous environments where standard ion-conducting systems often fail.<\/p>\n<p>Weichold, O.; Antons, U.C.<br \/>\n<em>Assessing the Performance of Hydrophobing Agents on Concrete Using Nondestructive Single-Sided Nuclear Magnetic Resonance<\/em><br \/>\n<em><i>Journal Of Infrastructure Systems<\/i> <b>2017<\/b>, <i>23<\/i> (4). <a href=\"https:\/\/doi.org\/10.1061\/(ASCE)IS.1943-555X.0000366\">https:\/\/doi.org\/10.1061\/(ASCE)IS.1943-555X.0000366<\/a><\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>The recent study by Prof. Dr. Oliver Weichold and Udo Antons explores the use of single-sided nuclear magnetic resonance (NMR) as a nondestructive method to analyze hydrophobing agents on concrete.
