THE EFFECT OF TEOS AS CROSS LINKING AGENT UPON MEMBRANE PROPERTY OF BLENDING OF PDMS AND PEG MEMBRANES

In this research blending of PDMS (polydimethylsiloxane) and PEG (poly ethylene glycol) membrane with crosslinking TEOS (tetra ethyl ortho silicate) as silica nano particles, ammonia as catalyst/inducer, and span 80 as surfactant. in this research ,variation of crosslinking agent (TEOS)upon crosslinking density (ve),swelling degree (MsD),%swelling by volume, density of membrane specimen (ρp),volume fraction of rubber phase(v2) and number average molecular weight between crosslink's (Mc),is studied. It was observed that with increase weight of the crosslinking agent (M), ve , ρp and v2, is increase and MsD , %swelling by volume and Mc is decrease.
