제목 | Preparation of monolithic porous polymers in supercritical carbon dioxide |
초록 | Experimental study on the preparation of monolithic porous polymers in supercritical carbon dioxide has been carried out. Polymerization mixture composed of a cross-linking monomer, initiator and functional co-polymer was charged in the reactor with sapphire window, prior to pressurized by supercritical carbon dioxide. After the system was purged with a flow of CO2 for 15 min, the reactor was pressured with liquid CO2 and shook until the mixture had become fully homogeneous. The reactor was then heated to the required reaction conditions and left overnight. After cooling and CO2 evacuation, the polymer was removed from the reactor as dry, white, continuous monoliths. The effects of experimental conditions(identity of monomer, monomer content, polymerization pressure, reaction time and method of CO2 evacuation) on the physical properties of porous polymer were systematically examined. |
