Glow-discharge reactor

The primary glow discharge reactor in this configuration could be used for plasma coating in a low-pressure regime, in principle however, in consideration of flow pattern in such a multiple shelves reactor and electrical field in multiple electrodes, it is difficult to achieve uniform coatings in such a mode of operation.

Fig. 35. Schematic view of the glow discharge reactor for the production of N QoA quartz tube with two electrodes is continuously flushed with nitrogen gas. The middle part of the tube in which Cgo powder is deposited is surrounded by an oven. Typical working parameters for the glow discharge are U = 500 V, Z = 1 mA and p 2 = 0,1 mbar. The Cgo fullerenes are sublimed at 450 °C and condense on the water cooled cathode where they are bombarded by nitrogen ions from the glow discharge...

Recently, we have studied a variety of sandwich type electrodes for development of enzyme electrodes based on oxidases. In this paper, we focused on extending linearity and blood-compatibility of the outer membrane, i.e., polycarbonate (PC) membrane, without affecting the selectivity. We modified the outer surface of this membrane by plasma polymerization of hexamethyldisiloxane (HMDS) in a glow-discharge reactor or by coating with polyvinylalcohol (PVAL). The PVAL coated surfaces were further treated with an anticoagulant, i.e., heparin. We studied the linearity, selectivity and blood-compatibility of these membranes and related electrodes. Here, we present the results of these studies. 

Glow-Discharge Treatment. HMDS was deposited by plasma polymerization on the PC membranes in a glow-discharge reactor system shown schematically in Figure 2. The reactor was a glass tube (inner diameter 6.4 cm and length 35 cm) with two copper electrodes (surface area of each electrode 140 cm ) mounted on the outside.
