“…The enthalpy of GO dissolution in water is smaller than in ethanol, 20 which means GO has a better affinity with water than ethanol. 21 In the case of GO powder dispersing in water, water molecules could insert into the interstitials of GO powder where water could freely pass through GO molecule layers by formation of hydrogen bonds, [22][23][24] intercalating GO powder into individual molecule layers. However, in the case of GO powder dispersing in ethanol, the intercalation of ethanol in GO molecules is strongly hindered.…”
