Who knows about the calculation of γ- phase percentage and β- phase percentage in PVDF (a kind of piezoelectric polymer)?

We could use following equation to calculate γ- phase percentage and β- phase percentage in PVDF:F(β) = Xβ / (Xα+Xβ) = Aβ / [(Kβ/Kα)Aα+Aβ]F(γ) = Xγ / (Xα+Xγ) = Aγ / [(Kγ/Kα)Aα+Aγ]Now I want to...

How can I make an aqueous solution of RGO-TiO2 or RGO-Cu or ...? In order for the powder not to settle at the bottom of the container quickly?

I synthesized RGO-TiO2 powder. Now I want to produce a solution of this powder with high dispersivity and for it not to settle quickly. I tested water and DMF but in both of them the powder...
