Abstract: front page image
(EN)The present invention relates to an electrically conductive polymer/filler composite and to a method for preparing same, using sea-island fibers formed during the blending of two types of polymers, structural characteristics such as a co-continuous phase structure, and selective dispersion characteristics of conductive fillers. The polymer/conductive filler composite according to the present invention comprises polycarbonate, poly(acrylonitrile-butadiene-styrene) copolymer, maleic anhydride graft styrene acrylonitrile copolymer, and carbon nanotubes. Here, the structure of the polymer blend is controlled by adjusting the ratio of the polycarbonate and poly(acrylonitrile-butadiene-styrene) copolymer, and the physical properties of the composite can be improved through the selective dispersion of the conductive fillers. According to the present invention, the method for preparing a polymer/conductive filler composite is carried out by molding the composition with a twin-screw extruder, and therefore the polymer/conductive filler composite has more enhanced electrical conductivity using the selective dispersion characteristic of the conductive fillers.
(FR)La présente invention concerne un composite polymère/charge, électriquement conducteur, et son procédé de fabrication, à l'aide de fibres île et mer formées pendant le mélange de deux types de polymères, des caractéristiques structurales telles qu'une structure de phases co-continues, et des caractéristiques de dispersion sélective de charges conductrices. Le composite polymère/charge conductrice selon la présente invention comprend du polycarbonate, un copolymère poly(acrylonitrile-butadiène-styrène), un copolymère styrène acrylonitrile greffé par anhydride maléique et des nanotubes de carbone. Ici, la structure du mélange de polymères est contrôlée par ajustement du rapport du polycarbonate et du copolymère poly(acrylonitrile-butadiène-styrène), et les propriétés physiques du composite peuvent être améliorées par la dispersion sélective des charges conductrices. Selon la présente invention, le procédé de préparation d'un composite polymère/charge conductrice est effectué par moulage de la composition à l'aide d'une extrudeuse à double vis, et de cette façon le composite polymère/charge conductrice a une conductivité électrique davantage accrue à l'aide des caractéristiques de dispersion sélective des charges conductrices.
(KO)본 발명은 두 고분자의 블렌딩 과정에서 형성되는 해도사, 상호연속상 구조 등과 같은 구조적 특징과 전도성 필러의 선택적인 분산특성을 이용하여 우수한 전기전도성을 갖는 고분자/전도성 필러 복합체 및 그 제조방법에 관한 것이다. 본 발명의 고분자/전도성 필러 복합체는 폴리카보네이트, 폴리(아크릴로니트릴-부타디엔-스티렌) 공중합체, 말레산 무수물 그래프트 스티렌 아크릴로니트릴 공중합체 및 탄소나노튜브를 포함한다. 이때, 폴리카보네이트와 폴리(아크릴로니트릴-부타디엔-스티렌) 공중합체의 비율을 조절하여 고분자 블렌드의 구조를 제어하고 전도성필러의 선택적 분산을 통해 복합체의 물성을 향상시킨다. 본 발명의 고분자/전도성 필러 복합체 제조방법은 상기 조성물들을 이축 압출기로 성형하여 이루어지며, 이에 따라 제조된 고분자/전도성 필러 복합체는 전도성필러의 선택적 분산 특성을 이용하여 보다 향상된 전기전도도를 가진다.
