Abstract
This study presents a modified Wilhelmy plate method designed to accurately measure effective contact angles on the non-flat surface with complex surface topology. The new technique allows for precise control of temperature and gas environment and captures real-time wetting dynamics between CO2 capture solvent and packings. The new approach is novel to carbon capture applications by accurately measuring the effective contact angle on non-flat surface and quantifying the effects of solvent with varying CO₂ loading on solvent wettability.
