P6.36Fri 911:<strong>10</strong>-14:00Mixture of PEG with the AOT microemulsion at X=40Soheil Sharifi 11 University of Sistan and Baluchestan, daneshgah st. , 98178, Zahedan, IranThe correlation function as a function of delay time was study by using photon correlation spectroscopy.The correlation function as a function of delay time shows a single strength exponentialfor AOT microemulsion with and without PEG. With increase of PEG concentration the delay timeis increasing and also shape of correlation function is changing that describe the polydispersity increasewith increase of concentration of PEG. In this work, the collective diffusion coefficient isconstructing from the correlation function as a function of delay time for the AOT microemulsionmixed with different concentration of PEG. Our results shows increase of PEG concentrationslowing down the dynamic of systems.36
