Abstract
THE INVENTION RELATES TO A METHOD OF MAKING A EPOXYSILICONE COATED MEMBRANE BY COATING A POROUS ASYMMETRIC MEMBERANC LAYER WITH A UV-CURABLE CONTROLLED RELEASE EPOXYSILICONE COATING A MIXTURE OF THE EEPOXYSILICONE RESIN AND AN ONIUM PHOTOCATALYST ARE APPLIED TO THE POROUS ASYMMETRIC MEMBRANE LAYER IN A DILURE NON-POLAR SOLUTION AND CURED BY UV OR ELECTRON BEAM RADIATION TO PRODUCE A DRY EPOXYSILICONC COATED MEMBRANE. THE POROUS ASYMMETRIC MEMBRANE LAYER IS COMPRISED OF AN ASYMMETRIC CELLULOSIC MEMBRANE OR AN ASYMMETRIC POLYMER MEMBRANE WITH A LOW SELECTIVITY. THE EPOXYSILICONE COATING WAS FOUND TO PROVIDE THE ASYMMETRIC MEMBRANE LAYER WITH IMPROVED SELECTIVITY WHICH EXTENDS TO SEPARATION TEMPERATURES BELOW 70°C AND PROVIDES STABLE FLUX RATES. MEMBRANES PRODUCED IN THIS MANNER ARE USEFUL FOR THE SEPARATION OF GASES SUCH AS CARBON DIOXIDE FROM NATURAL GAS.
