“…When this VUV photo-oxidation experimental set-up [4] was used to treat poly(ethylene terephthalate) (PET) [7], the results were in good agreement with a previous study where the oxygen was separated from the radiation emitted from MW plasmas of He-H 2 and H 2 by a MgF window having a cut-off wavelength of 112 nm [8]. The reaction time associated with the distance from the remote MW plasma results in negligible contributions from charged particles and metastables because of recombination and deactivation processes occurring in transit to the sample [9,10].…”

Because discarded polystyrene (PS) is little affected by degrading agents, PS was treated with a remote microwave (MW) plasma discharge of an Ar/O 2 mixture in the absence of radiation to increase wettability and introduce functional groups which make the waste more liable to degradation and useful for technological applications. X-ray photoelectron spectroscopy (XPS) detected decreases in the aromatic sp 2 and aliphatic sp 3 carbons with treatment and, initially, increases in C-O and carbonyl groups, present in the formation of ethers, epoxides, alcohols, ketones and aldehydes. At longer treatment times, ester, O-C=O; carbonate-like, O-(C=O)-O; and anhydride, O=C-O-C=O; moieties are observed with an overall oxygen saturation level of 23.6 ± 0.9 at% O. Atomic Force Microscopy (AFM) measurements detected little change in surface roughness with treatment time. Advancing water contact angle decreased by ca. 50% compared to pristine PS indicating an increase in hydrophilicity because of oxidation. Washing the treated samples in deionized water decreased the oxygen concentrations at the saturation treatment times down to 18.6 ± 1 at% O due to the washing away of a weak boundary layer.

“…As shown by the results, EGDMA was a better crosslinker compared to DAA and led to better surface grafting and, therefore, hydrophilicity. Lens et al, 15 in a similar study carried out on polypropylene and polyethylene, found that unsaturated surfactants, when coated along with crosslinkers, underwent efficient grafting; this resulted in a significant number of hydrophilic groups generating long-term wettable surfaces.…”

International audienceA 3 : 1 composition of functional monomer (FM)-multifunctional acrylate was spin-coated and later crosslinked under the influence of oxygen plasma on the surface of poly(dimethyl siloxane) (PDMS) to generate a surface-anchored crosslinked network bearing functional moieties. Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and wetting angle measurements were used to analyze the crosslinked monomer surfaces. Scanning electron microscopy was used to visualize the surface of the film after modification. The results of the surface reconstruction of the FM surfaces and plasma-treated PDMS reveal that long-term hydrophilic surfaces were achieved. Thus, the surface architecture could be favorably manipulated with this remarkable technique with a suitable combination of FMs and crosslinkers

“…It is the consequence of different processes such as oxidation, degradation, cross linking, and structural changes, which may occur in the thin surface layer. The efficiency of these processes depends on atmosphere, gas pressure and temperature, kind of polymer surface, power, and time of plasma action [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Treatment of polymers by different types of plasma (microwave, radio frequency, corona discharge) is often used for modification of wettability, printability, adhesion, durability, scratch resistance, hardness, membrane permeability [2][3][4], and compatibility with living tissues [6,12].…”

In this investigation, the surface modification of poly vinylidene fluoride (PVDF) and poly methyl methacrylate (PMMA) film induced by air plasma has been investigated using contact angle measurement, electron spectroscopy for chemical analysis (ESCA), and ATR‐FTIR spectroscopy. Plasma treatment affects the polymer surfaces to an extent of several hundreds to several thousand angstroms deep, and the bulk properties of the polymer substrate are never modified because of its low penetration range. Plasma surface treatment also offers the advantage of greater chemical flexibility. The plasma exposure leads to weight loss and changes in the chemical composition of the polymer film surfaces. The contact angle of water shows decrease in surface wettability of PVDF and PMMA as the treatment time increases. The improvement in adhesion was studied by measuring T‐peel strength. In addition, printability of plasma treated PVDF and PMMA was studied by cross test method. It was found that printability increases considerably for plasma treatment of short duration. Surface energy and surface roughness can be directly correlated to the improvement in the aforementioned surface related properties. POLYM. ENG. SCI., 2009. © 2009 Society of Plastics Engineers
