Effect of canopy structures and their steric interactions on CO2 sorption behavior of liquid-like nanoparticle organic hybrid materials

Abstract

Liquid-like NOHMs with different grafting densities of polymeric canopy were synthesized to evaluate their solvating properties as CO₂ solvents. The in situ ATR FT-IR study of NOHMs with linear and branched canopies revealed distinct CO₂ capture and corresponding swelling behaviors. These observations suggested that the entropic contribution for CO₂ sorption in NOHMs can be tuned via the canopy design.
