“…Comparing results with the previously published research, activation of PC in a homogeneous discharge is efficient: Gesche et al [22] applied the plasma gun at atmospheric pressure to modify the PC and obtained the change in the SFE from 42 to 57 mJ m −2 , but the virgin SFE was higher (compared with our 31 mJ m −2 ), the input power density was 20 times greater and the process time was 60 times longer. Chen et al [7] applied an inductively coupled plasma and obtained 55 mJ m −2 with the input power 16 times higher and the process time 4 times longer.…”

A homogeneous atmospheric pressure dielectric barrier discharge was used for the surface modification of polycarbonate (PC). The discharge was generated between two planar metal electrodes, the top electrode was covered by glass and the bottom electrode was covered by a polymer sample. The discharge burned in pure nitrogen or in a mixture of nitrogen and hydrogen. The surface properties of both treated and untreated polymers were characterized by atomic force microscopy, surface free energy (SFE) measurements and x-ray photoelectron spectroscopy. The influence of the treatment time and power input to the discharge on the surface properties of polymers was studied. The ageing of treated samples was also investigated. The treatment of polymers in the homogeneous atmospheric pressure discharge was homogeneous and the polymer surfaces showed a smaller degree of roughness in comparison with the polymer surfaces treated in a filamentary discharge. The SFE of the treated PC obtained at optimum conditions was 53 mJ m−2 and the corresponding contact angle of water was 38°. The maximum decrease in the SFE during ageing was about 13%. The analysis of the chemical composition showed an increase in the nitrogen concentration in the surface layer, but almost a zero increase in the oxygen concentration. This result was discussed concerning the measured values of the SFE measurement.

“…Using either vacuum plasma systems or cold atmospheric pressure plasma treatments creates a range of hydrophilic surface finishes that enhance cell adhesion [2][3][4]. Cold atmospheric plasma systems offer a number of advantages including in line manufacturing capability, rapid treatment, flexible scaling, and low maintenance requirements and these systems are compatible with a range of different polymer substrates [5,6]. In biological applications, the use of a nonthermal plasma can also allow the disinfection of surfaces without chemical additives or high temperatures [7][8][9].…”

Collagen coatings were applied onto polystyrene microplates using a cold atmospheric pressure plasma process. The coatings were compared to standard wet chemical collagen thin films using microscopy, surface energy, infra-red spectroscopy, electrophoresis, and cell culture techniques. Thin films were also deposited on gold electrodes using both coating methods and their structural and barrier properties probed using cyclic voltammetry. While the wet chemical technique produced a thicker deposit, both films appear equivalent in terms of coverage, porosity, structure, and chemistry. Significantly, the cold plasma method preserves both the primary and secondary structure of the protein and this results in high biocompatibility and cell activity that is at least equivalent to the standard wet chemical technique. The significance of these results is discussed in relation to the benefits of a single step plasma coating in comparison to the traditional multi-step aseptic coating technique.

“…[11][12][13][14][15][16][17][18] Low temperature process using a nonequilibrium atmospheric pressure plasma is sufficiently promising process for not only inorganic materials but also heatsensitive organic materials such as plastic. 19) Recently, an oxidation process at low temperature is required in the fabricating process of a contact lens made from plastic. A hydrophilic property of contact lens is very important for long-term use.…”

A surface modification process on the contact lens using a nonequilibrium atmospheric pressure remote plasma excited by three-phase AC power source has been investigated. Two dimensional spatial distributions of optical emissions of Ar and OH were measured, and gas temperature and electron density were estimated using the optical emission spectroscopy. It has been found that the gas temperature in the upstream region of the remote plasma is lower than that in the downstream region due to the interfusion of ambient air. The heat-sensitive material such as plastic could be processed without thermal damage by the nonequilibrium atmospheric pressure remote plasma in the proper low-temperature region.
