Abstract
(EN) The present invention relates to a method of improving aqueous dispersibility of conductive carbon powder, and to a method of preparing a colloid solution of conductive carbon powder. The present invention comprises a step of exposing conductive carbon powder to a plasma jet or reacting same with a plasma-treated reaction gas, wherein the step is characterized by reacting the plasma-treated reaction gas (ionized gas) with the conductive carbon powder, and accordingly by using plasma, the aqueous dispersibility of the conductive carbon powder can be improved in a convenient manner.
(FR) La présente invention concerne un procédé d'amélioration de la dispersibilité de poudre de carbone conductrice dans de l'eau et un procédé de préparation d'une solution colloïdale de poudre de carbone conductrice. La présente invention comprend une étape d'exposition de poudre de carbone conductrice à un jet de plasma ou de réaction de celle-ci avec un gaz de réaction traité par plasma, l'étape étant caractérisée par la réaction du gaz de réaction traité par plasma (gaz ionisé) avec la poudre de carbone conductrice et, en conséquence, par l'utilisation de plasma, la dispersibilité de la poudre de carbone conductrice dans de l'eau peut être améliorée de manière commode.
(KO) 본 발명은 전도성 탄소 분말의 수분산성 향상 방법 및 전도성 탄소 분말의 콜로이드 용액 제조 방법을 개시한다. 본 발명은 전도성 탄소 분말을 플라즈마 제트에 노출시키거나 플라즈마 처리된 반응가스와 반응시키는 단계를 포함하고, 상기 단계는 플라즈마 처리된 반응가스(이온화된 가스)를 상기 전도성 탄소 분말과 반응시키는 것을 특징으로 하며, 플라즈마를 이용함으로써 용이하게 전도성 탄소 분말의 수분산성을 향상시킬 수 있다.
