Abstract:
In this research for fabricated the membranes usagea blend of polymers that are comprised of PDMS (poly dimethylsiloxane), PEG (poly ethylene glycol), PES (poly ether sulfonic) and PAN (poly acryl nitrile) as polymers, a symmetric poly ester ultra-filtration membranes, PES, PVP (poly vinyl pyrrolidone) and N,N-Dimethyl acetamide (DMAc) as solvent used for fabricated of support layer with cross linking TEOS (tetra ethyl ortho silicate) as silica Nanoparticles (cross linking agent), ammonia as catalyst/inducer and span 80 as surfactant. In the research, four kinds of membrane including PDMS, blend of PDMS and PEG, blend of PDMS and PES, and blend of PDMS and PAN are used. In this research, variation of crosslinking temperature (T), from 65-85 Ċ upon density of membranes (ρp), swelling degree (MsD) and %swelling by volume, is studied. It was observed that with increase the crosslinking temperature, ρp is increased and MsD ,%swelling by volume is decreased.
Keywords: PDMS, TEOS, crosslinking Temperature, crosslinking agent, swelling degree
