プラスチックフイルムのコロナ照射による結晶質の析出(第1報)

Abstract

In recent years, with the progress of the high-polymer 'chemistry, many good physical, chemical and electrical characteristics of plastic materials were discovered and these are being studied in many fields. Especialy, by the ways of investigation of the mass changes of the sample by corona discharges and infra-red spectrometry and chemical analysis of the dicomposed gases, many people investigated the corona deterioration of the plastic electrical insulation materials. The mass changes of the plastic films by corona discharges shows a chemical and physical reaction which concludes the Ozonizing, Crosslinking, Polymerization and dissolution etc., by ozones and collision of the electrone. Where, recently, we discovered the crystalline materials which are thought as the dicomposed materials on a few plastic films by Corona discharges as poly-carbonate, polyethylene-terephtalate and cellulose-triacetate and the precipitation of these crystalline materials by Corona discharges depend on atmospheric conditions.
