“…The element composition and the atomic ratios of O/C and N/C derived from survey spectra for the four groups are given in Table I. The results of the element composition of control nylon microfiber artificial leather is in accordance with those describe in literature [2], [9], and [10]. The O/C ratios increased dramatically when the nylon microfiber artificial leather with O 2 plasma treatment.…”

Abstract-To improve surface wettability and dye-ability of Nylon microfiber artificial leather, we apply oxygen plasma treatment and subsequently graft-polymerize acrylamide (AAm) on the surface. The surface properties of AAm-grafted Nylon microfiber artificial leather are characterized by FT-IR, SEM, ESCA and dyeing density (C.I.reactive Blue 4). The dyeing rate of AAm-grafted Nylon microfiber artificial leather, up-regulated with higher acrylamide grafting concentration, increases to 67.1 mg/cm 2 , and remains 66.4 mg/cm 2 after rinsed by water, showed better stability than that of control and oxygen plasma modified Nylon microfiber artificial leather. The water-absorptivity of s-graft acrylamide is five times than that of control. From the results, the efficiency and density of dyeing are both improved, indicating that plasma graft polymerization process could contribute to promote the absorption of dye on the artificial leather.

“…Riekerink et al [45] have stated that CF 4 plasmas can create large changes in surface topography, since the CF 4 plasmas preferentially etch the amorphous regions of the polymer surface. Moreover, also Borcia et al [26,46] have stated that a DBD probably has a cleaning effect on polymer films by preferential physical etching of amorphous regions. Therefore, it is believed that the creation of the large number of depressions is due to the selective etching of the amorphous regions of the PP film.…”

Plasma surface modification is widely used to tailor the surface properties of polymeric materials. Most treatments are performed using low pressure plasma systems, but recently, atmospheric dielectric barrier discharges (DBDs) have appeared as interesting alternatives. Therefore, in this paper, an atmospheric He + CF 4 DBD is used to increase the hydrophobicity of a polypropylene (PP) film. The surface characterization of the PP film is performed using contact angle measurements, X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM). Results show that the hydrophobic properties of the polymer films are greatly enhanced after plasma treatment as evidenced by an increased contact angle. The incorporation of fluorine on the surface is significant (45 at%), demonstrating the ability of the used DBD set-up to generate fluorine-containing functional groups on the PP surface.

“…The methods used to modify a polymer surface are highly various, they can be thermal, mechanical, chemical, photochemical [1][2][3][4] or plasma [5][6][7]. One of the most promising methods are plasma surface modifications, which are preferred procedures as they are considered environmentally friendly.…”

Atmospheric pressure plasma treatment of polyamide-12 foils

Abstract:The surface of a polyamide-12 (PA-12) foil was modified in order to improve the adhesive properties by two types of atmospheric pressure plasma sources. The samples were characterized using contact angle measurement, adhesive properties measurement and X-ray photoelectron spectroscopy (XPS). The ageing of the plasma modification was also studied. A significant increase in wettability was observed at different treatment times. The same effect was also seen in the adhesive properties -the adhesion was increased almost 12 times for 10 s DCSBD treatment in comparison to untreated PA-12. XPS analysis confirmed chemical changes due to the plasma modification of the PA-12. It was concluded that both plasma sources improve the adhesive properties of PA-12, with DCSBD obtaining better results.
