“…The -potential measurement is advantageously used as one of methods for characterization of various materials [12][13][14][15]17,18]. The -potential measurements often supplement other analyses characterized surface properties, as X-ray photoelectron spectroscopy (XPS) [12,17], goniometry (contact angle) [12][13][14][15][16][17][18]26,28], atomic force microscopy (AFM) [12,14,17,27,28] or other measurements [14,17,28].…”

“…Zeta potential is used for characterization of natural and synthetic fibres and in investigation of their hydrophilicity, which is important for their interactions with dyes and surfactants [5,6,8]. It is also important for research of membranes, filters [10,11], pristine polymers [12][13][14][15] or polymers modified by plasma [12,[15][16][17][18], by laser or by chemical coatings, e.g. by chitosan [16], biphenyldithiol [17], polyethyleneglycol [18] or by gold coatings [14,17].…”

“…Surface properties of plasma treated polymers depend on, e.g., gases composition, exposure time, frequency and plasma power [8,12,13]. Polymers are often modified using noble gas (He, Ne, and Ar) or reactive gas (O 2 ) plasma [25,26]. In general, reaction of plasma with a polymer surface can be divided into three groups: surface reactions, which lead to functional groups production, plasma polymerization, cleaning and etching [3].…”

Rapid progress in thin-film coatings based on metals, which can be deposited on polymers, has been recently observed. In this work discussion on the properties of modified polymers and silver thin films deposited on polytetrafluoroethylene (PTFE) and polycarbonate (PC) substrates has been presented. Surface of these polymer substrates were exposed to argon plasma discharge. Additionally, silver thin films were deposited on their surface by electron beam evaporation method. The surfaces of the modified polymers were studied by different methods, i.e. topography, wettability and scratch resistance measurements were performed. The ageing effect of treated substrates was also discussed. It was shown that plasma modification of PTFE and PC substrates increased wettability of their surfaces. The value of water contact angle decreased of about 40 % and 25 % for PTFE and PC surface, respectively. The change of hydrophobic to hydrophilic properties was observed. Plasma modification of substrates improved adhesion between silver coating and polymer substrates. However, it did not influence wettability of Ag coating.

“…More detailed principles of this determination are presented in the study of Luxbacher et al [26]. For each measurement, a pair of polymer foils with the same top layer was fixed on two sample holders (with a cross section of 20 9 10 mm 2 and gap between 100 lm) [28,29]. All samples were measured four times at constant pH (pH 6.0) value with the relative error of 10 %.…”

Grafting of gold nanoparticles and nanorods on the surface of polymers, modified by plasma discharge, is studied with the aim to create structures with potential applications in electronics or tissue engineering. Surfaces of polyethyleneterephthalate and polytetrafluoroethylene were modified by plasma discharge and subsequently, grafted with 2-mercaptoethanol, 4,4 0 -biphenyldithiol, and cysteamine. The thiols are expected to be fixed via one of -OH, -SH or -NH 2 groups to reactive places on the polymer surface created by the plasma treatment. ''Free'' -SH groups are allowed to interact (graft) with gold nanoparticles and nanorods. Gold nano-objects were characterized before grafting by transmission electron microscopy and UV-Vis spectroscopy. X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and electrokinetic analysis (zeta potential determination) were used for the characterization of polymer surface at different modification phases. It was proved by FTIR and XPS measurements that the thiols were chemically bonded on the surface of the plasma-treated polymers, and they mediate subsequent grafting of the gold nanoobjects. On the surfaces, modified polymers were indicated some objects by AFM, size of which was dramatically larger in comparison with that of original nanoparticles and nanorods. This result and the other results of UV-Vis spectroscopy indicate an aggregation of deposited gold nano-objects.
