Title (EN) PREPARATION METHOD FOR REDUCED GRAPHENE OXIDE/ASPERGILLUS NIGER CELLULOSE AEROGEL
(FR) PROCÉDÉ DE PRÉPARATION D'AÉROGEL DE CELLULOSE RÉDUIT D'OXYDE DE GRAPHÈNE/ D'ASPERGILLUS NIGER
(ZH) 一种还原氧化石墨烯/黑曲霉菌纤维素气凝胶的制备方法
Abstract:
(EN) Provided is a preparation method for a reduced graphene oxide/Aspergillus niger cellulose aerogel, comprising (1), mixing a graphene oxide dispersion, Aspergillus niger and a culture medium solution, and co-culturing same under conditions suitable for Aspergillus niger reproduction so as to form a ball of Aspergillus niger coated with the graphene oxide dispersion; (2), washing the ball cultured in step (1) with deionized water until clean and freeze-drying and shaping same by utilizing a freeze-drying technology so as to form a graphene oxide/Aspergillus niger cellulose aerogel; and (3), subjecting the graphene oxide/Aspergillus niger cellulose aerogel prepared in step (2) to carbonization treatment so as to obtain the reduced graphene oxide/Aspergillus niger cellulose aerogel having hydrophobicity. The hypha obtained by the method has a stable structure, has a good hydrophobicity and lipophilicity, and can be used as an adsorbing material.
(FR) L'invention concerne un procédé de préparation d'un aérogel de cellulose réduit d'oxyde de graphène/d'Aspergillus niger,comprenant:(1) le mélange d'une dispersion d'oxyde de graphène, d'Aspergillus niger et d'une solution de milieu de culture, et la co-culture de ceux-ci dans des conditions appropriées pour la reproduction d'Aspergillus niger de façon à former une boule d'Aspergillus niger revêtue de la dispersion d'oxyde de graphène; (2) le lavage de la boule cultivée dans l'étape (1) avec de l'eau désionisée jusqu'à ce qu'elle soit propre et lyophilisée en utilisant une technologie de lyophilisation de façon à former un aérogel de cellulose d'oxyde de graphène/d'Aspergillus niger; et (3) la soumission de l'aérogel de cellulose d'oxyde de graphène/ d'Aspergillus niger préparé à l'étape (2) à un traitement de carbonisation de façon à obtenir l'aérogel de cellulose réduit d'oxyde de graphène/d'Aspergillus niger avec une hydrophobicité. Le hyphe obtenu par le procédé présente une structure stable, présente une bonne hydrophobicité et une bonne lipophilie, et peut être utilisé comme matériau adsorbant.
(ZH) 提供一种还原氧化石墨烯/黑曲霉菌纤维素气凝胶的制备方法,包括(1)将氧化石墨烯分散液、黑曲霉菌以及培养基溶液混合,在黑曲霉菌适宜繁殖的条件下进行共同培养,形成黑曲霉菌包裹氧化石墨烯分散液的菌球;(2)将步骤(1)培养的菌球用去离子水清洗干净并利用冻干技术冻干成型,形成氧化石墨烯/黑曲霉菌纤维素气凝胶;(3)将步骤(2)制成的氧化石墨烯/黑曲霉菌纤维素气凝胶进行碳化处理得到具有疏水性的还原氧化石墨烯/黑曲霉菌纤维素气凝胶。该方法得到的菌丝架构稳定,具有良好的疏水性和亲油性,可作为吸附材料使用。
