Abstract
A modified porous non-conductor is provided wherein its outer and inner, surfaces have been treated by placing the porous non-conductor between a pair of electrodes which are located opposite to each other and carry a dielectric layer on a surface facing the other electrode, respectively, so that the porous non-conductor is brought into contact with both dielectric layers without coming into contact with the electrodes; and then, applying an alternating current voltage having a frequency of about 0.1 Khz to about 100 Khz between the electrodes to thereby induce an electric discharge in voids contained in the porous non-conductor and sandwiched between a pair of the electrodes.
Claims5
A modified porous non-conducting article comprising an exposed surface and an unexposed surface, said surfaces having been modified by introduction of functional groups into the surfaces wherein an introducing-efficiency ratio (A) of a functional group introducing efficiency (A) of the exposed surface to which the functional groups have been introduced to a functional group-introducing efficiency (B) of the unexposed surface to which the functional groups have been introduced, is from 0.4 to 0.85 (0.45.ltoreq.A/B.ltoreq.0.85).
