摘要：
The present invention refers to a process for the preparation of a graphene dispersion comprising the following steps: i) providing cellulose acetate flakes or powders; ii) swelling the cellulose acetate flakes or powders in an alcohol having from 1 to 3 carbon atoms; iii) adding acetic anhydride in a concentration range from 30 to 50 wt% referred to the total weight of the mixture; iv) adding graphene nanoplatelets to yield a graphene dispersion. The graphene dispersion is used as ink for composite materials that are employed in the field of foldable electronics. The invention relates also to a composite material comprising uniformly dispersed graphene nanoplatelets and its use for manufacturing electronic devices
摘要（中）：
本发明涉及制备石墨烯分散体的方法，其包括以下步骤：i）提供乙酸纤维素薄片或粉末; ii）将乙酸纤维素薄片或粉末溶胀在具有1至3个碳原子的醇中; iii）以相对于混合物总重量的30-50重量％的浓度添加乙酸酐; iv）添加石墨烯纳米片以产生石墨烯分散体。 石墨烯分散体用作可折叠电子领域中使用的复合材料的墨水。 本发明还涉及包含均匀分散的石墨烯纳米片的复合材料及其用于制造电子器件的用途
