“…4,5,13 Weikart and Yasuda 13 reported that plasma-induced surface damage of polymers resulted in the formation of a certain amount of low-molecular-weight oligomers which were washed away after immersion in water. To compare the effects of LTCAT treatments, in this study RF plasma treatments of LDPE were investigated by varying plasma exposure time, while keeping RF power, system pressure, and flow rate fixed.…”

“…Ample data indicate that this "uncontrollable" plasma treatment can bring about many undesirable changes in and damage to the surface of polymers, such as degradation of polymer chains and etching of the surface materials. 4,5 These undesirable changes and damage of polymer surfaces have many detrimental effects on their applications, such as loss of wettability, adhesion failure from weak-boundary-layer (WBL) formation, and loss of tensile strength of polyethylene fibers resulting from plasma etching. 6,7 If a desirable surface modification is accomplished at the expense of degradation of the substrate, the value of such a modification is questionable.…”

Low-density polyethylene (LDPE) was treated with a low-temperature cascade arc plasma torch (LTCAT) of argon with or without adding a reactive gas of oxygen or water vapor. The static sessile droplet method and the dynamic Wilhelmy balance method were employed to perform surface contact angle measurement in order to investigate and characterize the effects of LTCAT treatment on LDPE surfaces. These treatment effects included changes in surface wettability and surface stability and possible surface damage that would create low-molecular-weight oligomers on the treated surface. Experimental results indicated that the combination of static and dynamic surface contact angle measurements enabled a comprehensive investigation of these effects of plasma treatment on a polymer surface. Without the addition of a reactive gas, a 2-s argon LTCAT treatment of LDPE resulted in a stable hydrophilic surface (with a water contact angle of 40°) and little surface damage. The addition of oxygen into argon LTCAT produced a less stable LDPE surface and showed more surface damage. Adding H 2 O vapor into argon LTCAT produced an extremely hydrophilic surface (with a water contact angle Ͻ 20°) of LDPE but with pronounced surface damage. When compared with conventional radio frequency (13.56 MHz) plasmas, LTCAT treatment provides a much more rapid, effective, and efficient method of surface modification of LDPE.

“…As plasma polymers are derived from the assembly of various molecular fragments produced in the plasma vapour phase, their chemical structure tends to be random and more cross-linked compared to conventional polymers [3]. Moreover, plasma-polymerised films are generally amorphous, free from pinholes, highly resistant to heat and corrosion and very adhesive to a variety of substrates including conventional polymer, glass and metal surfaces [6][7][8]. Owing to these excellent characteristics, plasma polymers have been used in a wide variety of applications including barrier coatings, protective coatings, selective permeation membranes, dielectric layers in microelectronics, … [9].…”

The present work describes the plasma polymerisation of acrylic acid at atmospheric pressure. The influence of two operating parameters (monomer concentration and discharge power) on the properties of the deposited films is investigated. Results show that at a monomer concentration of 2.5 ppm and a discharge power of 9.5 W, the monomer is only slightly fragmented leading to a high amount of carboxylic acid groups on the deposited films. In contrast, when monomer concentration is decreased or discharge power increased, the incidence of monomer fragmentation processes is higher, leading to a lower amount of carboxylic acid groups on the films. This behaviour can be explained by a higher energy amount available per monomer molecule at low monomer concentrations and high discharge powers and a higher flux of positive ions attacking the surface at high discharge powers. Taking into account these results, it can be concluded that the deposition parameters should be carefully selected in order to preserve the stability of the monomer and thus obtain coatings with high carboxylic acid densities

“…Plasma polymerization process refers to formation of thin polymer films by fragmentation of organic compounds into radicals and their recombination during film growth [3][4][5][6]. Due to the unique properties such as good adhesion to substrates, highly cross-linked layers and controlled thickness at nanoscale [7] the plasma polymerized films are becoming increasingly important for a wide range of applications, from functional coatings for biomolecules immobilization [8] to dielectric materials in microelectronics and nanoelectronics.…”

Atmospheric pressure plasma co-polymerization of ethylene glycol and styrene was applied to produce poly (ethylene glycol-co-styrene) using a dielectric barrier discharge. The chemical structure of polymerized films was studied by Fourier-transform infrared spectroscopy which confirms that we obtained copolymerized films with hydroxyl groups incorporated. Chemical composition of films was studied by X-ray Photoelectron Spectroscopy and oxygen containing groups (C-O and C=O) were identified. Topography of polymer films was revealed using Atomic Force Microscopy technique and the film root mean square roughness (R rms ) was found to be 1.6 nm. Surface wettability was analyzed using water contact angle technique.
