I need to determine the charge of a paper substrate doped with metal nanoparticles and polymer. Since zeta potential analysis is applied to solutions in general, I'm looking for any alternative ways of it.
Thanks.
As your sampe is solid, I would like to clarify whether you are looking for surface charge or zeta potential. Please find enclosed the following discussion. https://www.google.com/amp/s/www.researchgate.net/post/What_is_the_difference_between_surface_charge_and_zeta_potential/amp
Dear Sarvar Kakhkhorov, there other possibilities. Conductimetry and potentiometric titration are well applied in the field of polyelectrolytes. My Regards
I did not payed attention to the fact that you want to work on solid. I think STM and/or AFM may be used. Regards

Christian Harito Many thanks for your reply. I'm looking for surface charge of a paper substrate.
It has been mentioned by @Abdelkader Bouaziz . You can use AFM with electrostatic mode https://www.ntmdt-si.com/resources/spm-principles/atomic-force-microscopy/electrostatic-force-modes
Or using SEM modelling https://www.researchgate.net/publication/249513948_Measuring_interface_electrostatic_potential_and_surface_charge_in_a_scanning_electron_microscope
Hi
Yiu can go fir LCR meter where yiu can find the charge of sample
Best
Different techniques have been developed to measure surface charge, including potentiometric titration, atomic force microscopy, reflection interference contrast microscope and Surface Plasmon Resonance (SPR).
