본 발명은 하기 단계를 포함하는 폴리아닐린(polyaniline)/환원된 그래핀 옥사이드 (reduced graphene oxide) 조성물 제조 방법을 제공한다. 단계 1: 분산된 그래핀 옥사이드를 제조하기 위해, 음이온의 유화제를 함유하는 산성의 수용액에서 그래핀 옥사이드를 분산하는 단계; 단계 2: 올리고머 용액을 제조하기 위해, 유기용매에서 선택적으로 치환된 아닐린의 하나 또는 그 이상의 올리고머를 용해시키는 단계; 및 단계 3: 폴리아닐린(polyaniline)/환원된 그래핀 옥사이드 (reduced graphene oxide) 조성물 제조하기 위해, 상기 단계 2에서 제조한 올리고머 용액과 상기 단계 1에서 제조한 분산된 그래핀 옥사이드를 혼합하는 단계. Methods for obtaining composites of polyaniline and reduced graphene oxide are disclosed. The methods include dispersing graphene oxide in an acid aqueous solution containing an anionic emulsifying agent to obtain a dispersion of the graphene oxide, dissolving an aniline oligomer in an organic solvent to obtain a solution of the oligomer, and mixing the solution of the oligomer with the dispersion of graphene oxide to obtain a composite of polyaniline and reduced graphene oxide. The methods may also include recovering a precipitate of the polyaniline/reduced graphene oxide composite, and dissolving the precipitate in an organic solvent to form a conductive ink or an ink for electronic devices.
