The colloidal stability of graphene oxide (GO) and its reduced forms can be described using classical DLVO theory. This contradicts the claims by Qi et al. (Environ. Sci.: Nano, 2016, 3, 1062–1071). Lower colloidal stability of reduced GO is caused by changes in surface charging and optical properties of GO upon reduction which leads to the suppression of double layer forces but enhancement of van der Waals forces, respectively.

可以使用经典的DLVO理论描述氧化石墨烯(GO)的胶体稳定性及其还原形式。这与Qi等人的主张相矛盾环境科学:纳米,2016年,3,1062年至1071年)。还原的GO的胶体稳定性较低,是由于GO还原后表面电荷和光学性质的变化引起的,分别导致双层力的抑制和范德华力的增强。
