摘要： The present invention provides a composite reverse osmosis membrane as a polyamide membrane including a side chain amino group such as a residue of a polyvinyl alcohol-based amine compound represented by Formula 1. Such a membrane can remove organic impurities under a low pressure, providing an economical method for removal of impurities. An aqueous solution including a polyvinyl alcohol-based amine compound having a side chain amino group represented by Formula 1 is applied on a polysulfone-based ultrafiltration membrane as a microporous support. Next, trimesic acid chloride solution is applied causing interfacial polycondensation, which generates a reverse osmosis membrane. When this composite reverse osmosis membrane is evaluated by using a pH 6.5 aqueous solution including 500 mg/l of sodium chloride at an operation pressure of 5 kg/cm2 and at a temperature of 25° C., the permeable flux is at least 1.5 m3/m2·d, and the salt rejection is 80% or less. wherein 0

摘要： Cationic charged semihydrophobic polyethersulfone (CSfIP) membranes having hydrophilic and semihydrophobic properties are provided, as well as preparation of the same by post-treatment. Typically, as an illustration, a microporous hydrophilic polyethersulfone membrane substrate which contains non-leachable polymeric additive having functional groups is treated in an alkaline solution for simultaneous or sequential reaction with 1) a primary charge modifying agent which is an epichlorohydrin modified polyamine, and 2) a secondary polymeric charge modifying agent containing a positive charge (or for reaction with the primary charge modifying agent alone); then baked until cured at elevated temperature; and finally washed and dried. The CSHP membranes are used in various applications such as the filtration of fluids and the macromolecular transfer of biomolecules either from electrophoresis gels or directly to immobilization on the membrane for hybridization and stripping. The CSHP membranes--unlike conventional charged membranes which typically show a decrease in sensitivity and reprobing performance--retain their sensitivity and reprobing performance and excel in this regard throughout multiple reprobing cycles.
