Hydroxy-Functionalized PAMAM Dendrimer as a CO₂-Selective Molecular Gate for CO₂ Membrane Separation

Abstract:

Two hydroxy-functionalized PAMAM Dendrimers (3OH-PAMAM and 4OH-PAMAM) were developed as immobilized liquid membranes (ILMs) to separate CO₂ from a mixture of CO₂ and N₂. The hydroxy-functionalized PAMAM demonstrated excellent properties of CO₂-selective separative material for CO₂ membrane separation. The hydroxy-functionalized PAMAM dendrimers displayed greater water sorption and more CO₂ separation properties than that of conventional PAMAM without hydroxy groups. The resulting ILMs of 4OH-PAMAM showed the highest CO₂ over N₂ selectivity of 7000 and above with CO₂ permeance of 1.1×10⁻¹¹ m³ (STP) m⁻² s⁻¹ Pa⁻¹ (1.5 GPU, 1 GPU = 7.5 × 10⁻¹² m³ (STP) m⁻² s⁻¹ Pa⁻¹), with a membrane thickness of 100µm (CO₂ permeability 147 Barrers), at 9.7 kPa CO₂ partial under 130 kPa feed pressure with 80% RH at 40 °C. For the ILMs of dendrimers at over 60%RH, their P_CO2 – α plots exceeded the upper bound line by Roberson in 2008 and that is a potential for CO₂ separation from the gas mixture.
