THE EFFECT OF TEOS AS CROSS LINKING AGENT UPON MEMBRANE PROPERTY OF PDMS MEMBRANE

In this research beneficial of PDMS (poly dimethylsiloxane) 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 cross links (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
