Via LCR hi tester we can find the static electricity in a film

Try it

Best

Dimitar P. Mitev

a) pH influences the charge in water in a lot of cases;

b) electrostatic interaction with charged particles or surfaces is an option here.

Azeem Mushtaq

Thanks for your kind answers. I used zetasizer to measure zeta potential, which was further used to discuss the surface charge on different films.

Dimitar P. Mitev and V R Arun Prakash thanks for your kind answers.

Good luck Azeem Mushtaq .
