How much quantity of pvdf and dmf is required to make film on aluminium coated glass and aluminium coated silicon wafer
Pvdf powder form weight in grams
And dmf in ml how much quantity is required to make 5,10 and 15 weight percent solution
Dear Dr. Bhuvash Jolly ,
PVDF was dissolved in DMF, typically at 10 wt%. The dissolution temperature of 100 °C is about 40 °C to ensure thermodynamic equilibrium. At low temperatures very small crystallites exist, two to partial dissolution or refolding of the polymer chains, which serves as nuclei when the solution is recrystallized.
To fabricate uniform films, wire-bar coating was used in order to permit an accurate control of the substrate temperature that was varied between 20 °C and 120 °C.

Good work and best regards, Pierluigi Traverso.
Sir how much quantity of pvdf in grams and dmf in millilitres is required to make 10 weight percent
Dear Dr. Bhuvash Jolly,
if I'm not mistaken, the density of the DMF is 0.944 g / cm3 (at 20 ° C).
To obtain a 10% weight ratio, you should dissolve, for example, 10 g of PVDF in 105.9 ml of DMF.
Without carrying out any calculation, you could weigh a beaker, reset zero as tare and add 100 g of DMF (corresponding to 105.9 cc), then dissolve 10 g of PVDF, previously weighed.
Best regards, Pierluigi Traverso
