Thank you for your comprehensive comment. my polymer is poly lipoic acid and i doesn't have any cationic head, so should I somehow add a cationic end group to this polymer to make it stable on the mica?

Dear all I want to use Mica as the substrate to immobilize polymer on it and visualize it under AFM. is there any body who has worked with Mica before? is there any specific trick in working with Mica? could you please describe from the scratch step by step how to use it? Thanks

Teddy Thanks for your reply, but the KPFM mode which I'm working with is AM, is it capable of measuring electrostatic charge?

Hi I'm wondering if I can find about electrostatic charges on a polymer ( PVDF) with KPFM mode. Is there any relation between electrostatic charge and volta potential? if yes how they are correlated?
