低温プラズマによる高分子ミクロスフィアの帯電制御 Triboelectric Charge Control of Polymer Microspheres by Low Temperature Plasma Treatments
A rotary kiln type reactor is developed to control the triboelectric charge of crosslinked polystyrene microspheres by low temperature plasma treatment. Four kinds of plasma gass (Ar, O<SUB>2</SUB>, CO<SUB>2</SUB> and NH<SUB>3</SUB>) were used as plasma gases. From surface analysis and measurements of the triboelectric charge of plasma-treated microspheres, the following results are obtained.<BR>(1) Plasma treatment with various gases makes it possible to incorporate various functional group such as amino, carbonyl and peroxy groups on the surface of the microspheres.<BR>(2) Sign and triboelectric charge of the polymer microspheres are able to be charged by changing charge gas and treatment time, respectively.
