A comparison of plasma-oxidized and photo-oxidized polystyrene surfaces

Surface modification of polyethylene powder by nitrogen and ammonia low pressure plasma in a fluidized bed reactor

“…It is well known that plasma treated polymers stored in air at room temperature lose their enhanced wettability to a great extent [26][27][28][29][30][31][32]. This effect generally occurs within the first few hours of exposure to air.…”

Surface modification and functionalization through the self-assembled monolayer and graft polymerization

“…Surface modification of materials with functional polymers is an important research area in polymer science due to the wide applications of polymers in the fields of adhesion, biomaterials, protective coatings, friction and wear, composites, microelectronics, and thin-film technology [1][2][3]. Generally, these surface-modification methods can be divided into two classes: physical modifications [4][5][6][7][8][9][10] and chemical modifications [11][12][13][14][15][16].…”

Testing Methods of Weathered Specimen

“…X-ray photoelectron spectroscopy, XPS, 16,22,59,79,96,119,142,157,199,306,[354][355][356][357][358][359][360][361][362][363][364][365][366][367][368] also called "electron spectroscopy for chemical applications", ESCA, is a relatively new method in its applications to weathering studies but it has become one of the most frequently used methods. With it, quantitative analysis of oxygen, carbon, and nitrogen, and any heavier element available on the surface is possible.…”

“…306 This raises the question whether the radiation source is the reason for discrepancies with other studies? 356,357 More oxidation occurs in the presence of oxygen than in the presence of nitrous oxide even though nitrous oxide is more reactive. There is no perfect agreement.…”
