요약This study focuses on advancing Direct Air Capture (DAC) technology for atmospheric carbon dioxide reduction, employing novel polyimine materials. The study, from a computational perspective, investigates traditional poly(ethylenimine) (PEI) sorbents and novel poly(propylenimine) (PPI) and their derivatives, addressing the pressing environmental challenge of CO2 accumulation. The research encompasses the following objectives: exploring CO2 transport in the hyperbranched PEI/MCM-41 hybrid system, in-depth investigation of CO2 transport in hyperbranched PPI membranes and corresponding MCM-41 systems. Central to the dissertation is the use of multiscale modeling, including First-principles calculations and Molecular Dynamics (MD) simulations for understanding molecular behaviors in the CO2 capture processes. This involves the development of new force field parameters to accurately describe interactions between CO2, water, amine groups, and silica surfaces, alongside characterizing CO2 distribution and movement through pair correlation and mean-square displacement analyses. The study is set to provide significant insights into the enhancement of CO2 capture within these systems and contribute to the development of new materials with improved capture performance. This research outcome is expected to substantially elevate the efficacy and practicality of DAC technology, potentially leading to reduced costs and energy demands, and aligning with global efforts towards carbon neutrality and sustainable industrial processes.
