Abstract

PURPOSE: To eliminate unevenness of treatment and to improve treatment efficiency, by disposing two electrodes having planar electrode surface in the same plane in imparting hydrophilicity to the surface of a hydrophobic resin molding by treating the molding with a low-temperature plasma.
CONSTITUTION: A central electrode 10 having a circular electrode surface 11 and a peripheral electrode 20 having an annular electrode surface 21 are disposed within a base 30, a bell jar 40 is mounted on the base 30 and a contact lens to be rendered hydrophilic, made of a hydrophobic resin (e.g., methyl methacrylate) is placed on a sample mount 24. Then, the space for plasma generation 50 is evacuated, then, charged with a gas, such as air, oxygen or argon, introduced from a gas inlet pipe 22, and maintained at a predetermined gas pressure, a voltage is impressed between the central electrode 10 and the peripheral electrode 20, and the surface of the contact lens 25 is treated with the low-temperature plasma generated and is rendered hydrophilic. According to this process, a plurality of samples can be treated simultaneously.
