Abstract:
1. A corona sensing device, comprising: a support member; a first electrode and a second electrode placed on the support member; a semiconducting film disposed on the support member and the first and second electrodes, the semiconducting film comprising an organic charge transporting material comprising from about 20% to about 80% N,N′-diphenyl-N,N′-bis(3-methylphenyl)-1,1′-biphenyl-4,4′-diamine and from about 20% to about 80% polycarbonate; a first wire lead and a second wire lead allowing for connection of the first electrode and the second electrode to an external resistivity monitoring circuit, wherein a measurement of a decrease in resistivity indicates the detection of corona effluents; and a heating device for resetting the corona sensing device after exposure to corona effluents by applying a mild heat treatment of from about 50° C. to about 100° C.
