Adhesion properties of glow‐discharge‐plasma‐treated polyethylene surface

Abstract

A geometric method proposed by Kaelble and Moacanin for analyzing energetic characteristics of solid surfaces is discussed. It is shown that a number of characteristics can be presented in a visual geometric form. The method is applied to the analysis of adhesion in a three-component system. Results of the analysis, concerned with the problem of creation of biocompatible materials, support the Andrade hypothesis that materials with zero interfacial tension of their water-solid interface show maximum biocompatibility. Data are obtained on wetting of polyethylene by different liquids before and after glow discharge plasma treatment. The analysis of these data in terms of geometric method shows the plasma treatment increased the polar component of the polymer surface energy to change the surface adhesiveness toward probable enhancement of polymer biocompatibility. That is consistent with available data on glow-discharge-treatment enhancement of biocompatibility for a number of polymers.

Coating of Anionic Surfactants onto Poly(ethylene) Surfaces Studied with X-ray Photoelectron Spectroscopy

“…When PE samples are treated with an argon plasma for 5 s (PE-Ar 5 samples), oxygen-containing groups are introduced at the surface of the polymer (Table ). Due to the presence of oxygen-containing groups, the value of γ SA is increased and γ SL is decreased . This was reflected in relatively low advancing and receding water contact angles of PE-Ar 5 samples (θ a = (89 ± 2)°; θ r = (31 ± 7)°) compared to those of untreated PE (θ a = (109 ± 1)°; θ r = (83 ± 2)°).…”

Grafting effect on the wetting and electrochemical performance of carbon cloth electrode and polypropylene separator in electric double layer capacitor

“…The surface tension and its polar and dispersive components were calculated according to harmonic averaging [22]. The polar and dispersive components of surface tension for testing liquids were taken according to Kuznietsov et al [23]. Sample polarity was defined as a percent ratio of the polar component of surface tension and total surface tension.…”

Comparison of surface energies using various approaches and their suitability

“…Thus, one can determine Lifshitz-van der Waals i.e., LW parameter (disperse component) of a solid or a liquid if all other parameters are known. The SE characteristics such as g lv , g LW , g AB , g þ , and g 2 various pure liquids are compiled from the literature 15,20,[32][33][34][35] and is reproduced here in Table II. The SE (S.T.)…”
