摘要:
The trisilanol isobutyl polyhedral oligomeric silsesquioxane(POSS) was fabricated into liquid-like nanoparticle organic hybrid materials(NOHMs) with γ-(2,3-epoxypropoxy)propytrimethoxysilane as corona and polyetheramine M2070 as canopy, and the product was called liquid-like POSS NOHM. The liquid-like POSS NOHM has a low viscosity at room temperature without any solvent and the mass fraction of trisilanol isobutyl POSS was 23.38%. The liquid-like POSS NOHM shows great CO2 capturing property with a capacity of 2.108 mmol/g(pCO2=6 MPa). The physical adsorption increased obviously with the pressure going up and it may make a difference between liquid-like POSS NOHMs and traditional monoethamolamine(MEA) based CO2 absorbent. The recycle property was also studied. The NOHM behaved as fresh product even after 10 cycles.
