摘要: 设计两步法，采用石墨烯量子点作为自组装媒介，并以异丙醇作为分散剂制备Al/CuO亚稳态分子间复合物。在有机体系中所制备的复合物其放热量明显高于在水体系中制备的对应样品，其原因来自于Al与CuO纳米颗粒通过有机体系自组装获得的更多的组分间接触面积。进一步地，通过使用乙酸对Al纳米颗粒外侧Al2O3氧化层进行刻蚀，复合物的反应放热量与瞬时热流率得到提高。
Abstract: Al/CuO metastable intermolecular composites (MICs) were prepared with graphene quantum dots as the self-assembly media and through a two-step method with isopropanol as the solvent. The as-assembled MICs exhibit higher heat release than those prepared in aqueous solution, owing to more intimate surface contact between Al and CuO nanoparticles. The reaction rate evaluated from peak heat flow in differential scanning calorimetry curves was further enhanced by etching the Al2O3 passivation layer on Al nanoparticles with acetic acid.
