摘要： Hydrophobic polymer materials having improved dyeability with water-based dyes are prepared by treating a hydrophobic polymer with aglow discharge plasma generated from working gases selected from SO2, O2, N2, He, H2, CO2, CF4, NO, N2O, 2-Hydroxypropyl Methacrylate (HPMA), air or combinations thereof, in which a treated material comprises a hydrophobic inner core and a hydrophilic outer sheath having polar functional groups. A method of treating hydrophobic polymer materials using a glow discharge plasma, preferably at high pressure (e.g., about 50 Torr or greater), thereby modifying the active surface characteristics of the polymer to contain polar functional groups is also presented.

摘要： A pair of electrodes are biased to produce an electrostatic discharge while placing a thin non electron absorbing gas layer near one or both of the electrodes which are used to develop the electric field. As a result, atmospheric oxygen, water vapor and other contaminants are removed from the regions surrounding the electrodes, allowing ionization to occur more easily. This is accomplished with an electrode structure including a hollow tube for receiving a gas, a plurality of apertures extending through the hollow tube for delivering the gas to the surface of the hollow tube, and the application of a biasing voltage for producing an electrostatic discharge in the presence of the gas. The tube can take the form of a longitudinally extending structure, or a hollow shell, depending upon the configuration of the electrostatic charging apparatus with which the electrode structure is used.
