Revisiting the surface characterization of plasma‐modified polymers

Abstract

Many papers dealing with the surface analysis of plasma polymers or plasmamodified polymers report the use of X-ray photoelectron spectroscopy (XPS) to quantify the surface composition. However, most of the time, quantification is performed using software that includes an equation based on the assumption that the sample is homogeneous in composition. However, for plasma-treated samples, this is often not the case. The usual analysis of XPS spectra does not allow the exact quantification in the case of an inhomogeneous sample. In this paper, we show that it is possible to obtain a depth profile of the composition, and a more accurate surface composition by using another mathematical approach for surface quantification, being QUASES Tougaard.depth profile, plasma-polymerized propargyl methacrylate, QUASES Tougaard, water contact-angle (WCA), XPS

Atmospheric Pressure Plasma Jet Exposure of Polylactic Acid Surfaces for Better Adhesion: Plasma Parameters towards Polymer Properties

“…Hence, the need to have knowledge of all these parameters prompts the invention and optimization of the novel physico-chemical techniques capable of altering them. As previously stated, subjecting polymers to atmospheric pressure non-thermal plasma can be a viable method for altering the surface and manipulating the structure through physical or chemical processes such as cleaning, etching, crosslinking, functionalization, and even polymerization [ 4 , 15 , 16 , 17 ]. The operating characteristics of plasma, such as applied voltage, discharge current density, electrical mean power, total power of emitted radiation, and excited and reactive species, have an impact on the primary processes occurring at the interface between plasma and polymer.…”

“…Thus, understanding these characteristics helps in the development and improvement of new physicochemical methods to change them. Polymers can be functionalized, cleaned, etched, and crosslinked using atmospheric pressure non-thermal plasma [7,[24][25][26].…”
