Zusammenfassung:Disclosed are: a method for preparing a porous carbon structure, capable of dramatically increasing the surface area and total pore volume of the porous carbon structure; and a porous carbon structure prepared using same. The method of the present invention comprises the steps of: preparing a template having a mesoporous shell; injecting a carbon precursor into the template, the carbon precursor comprising a polymer precursor and a cross-linking agent, the polymer precursor comprising a first component, which has a halogen functional group, and a second component, which does not have a halogen functional group, and the amount of the first component in the polymer precursor being 20-80 wt%; polymerizing the polymer precursor to form a polymer; carbonizing the polymer to obtain a template-carbon complex; and removing the template from the template-carbon complex. L'invention concerne : une méthode de préparation d'une structure de carbone poreux, capable d'augmenter considérablement la surface et le volume poreux total de la structure de carbone poreux ; et une structure de carbone poreux préparée à l'aide de celle-ci. La méthode de la présente invention comprend les étapes consistant à : préparer une matrice ayant une enveloppe mésoporeuse ; injecter un précurseur de carbone dans la matrice, le précurseur de carbone comprenant un précurseur de polymère et un agent de réticulation, le précurseur de polymère comprenant un premier composant, qui a un groupe fonctionnel halogène, et un second composant, qui n'a pas de groupe fonctionnel halogène, et la quantité du premier composant dans le précurseur de polymère étant de 20 à 80 % en poids ; polymériser le précurseur de polymère pour former un polymère ; carboniser le polymère pour obtenir un complexe matrice-carbone ; et retirer la matrice du complexe matrice-carbone. 다공성 탄소 구조체의 표면적 및 전체 세공 부피를 획기적으로 증가시킬 수 있는 다공성 탄소 구조체 제조방법 및 이를 이용하여 제조된 다공성 탄소 구조체가 개시된다. 본 발명의 방법은, 메조다공성 쉘을 갖는 주형을 준비하는 단계; 탄소 전구체를 상기 주형에 주입하는 단계 - 상기 탄소 전구체는 고분자 전구체 및 가교제를 포함하고, 상기 고분자 전구체는 할로겐 작용기를 갖는 제1 성분 및 할로겐 작용기를 갖지 않는 제2 성분을 포함하며, 상기 고분자 전구체 내 상기 제1 성분의 함량은 20 내지 80 중량%임 -; 상기 고분자 전구체를 중합시켜 고분자를 형성하는 단계; 상기 고분자를 탄화시킴으로써 주형-탄소 복합체를 얻는 단계; 및 상기 주형-탄소 복합체로부터 상기 주형을 제거하는 단계를 포함한다.
