Quantitative Investigation on the Contributing Factors to the Contact Angle of the CO₂/H₂O/Muscovite Systems Using the Frumkin-Derjaguin Equation

Figure 2

Dependence of on the Hamaker constant . For the water film sandwiched between CO₂ and muscovite, is negative and repulsive forces act on the film. The decrease in the repulsive forces lead to the decrease in the integration part (the red colored area in Figures S1 and S2). This means that increasing pressure leads the system to being less water wet (increase in the contact angle). for each pressure is from Table 1.
