In my research, I must disperse Al2O3, Tio2 and ZnO nanoparticles in ethanol (96 %), but I don't know which surfactant is suitable.
In this research the surfactant should not have a great effect on the surface tension.
If the nanofluids remain stable for 1 hour, it will be enough for me.
Would you suggest to me the suitable surfactant for each nanoparticle? And how much of them should be used?
Nanoparticles properties :
Al2O3: 20-30 nm - Gamma
Zno : 20-35 nm
Tio2 :20-25 nm - Rutile
Ethanol : 96 %

Selection of surfactant depends on the zeta potential analysis. You can check the zeta potential first and then you can choose the right surfactant suitable for ethanol based nanofluid.
