To conduct a heating experiment in order to understand the sample’s stability and exothermic phenomenon of thermal decomposition reaction. As temperature was increased, the sample was triggered for exothermic reaction.

hence generally it doesn't need electroplating i suppose

You no need to do electroplate actually.

I had measured some flexible polymer films embedded with Fe3O4 NPs (Published) and even CNTs (not published yet)

For more information about the calculation of specific heat capacity and glass transition temperature etc. Please see the attached articles.

Hi Mahmoud . In dsc experiment, heat flow changes are measured relative to the reference sample. So, there is no need for electropolating.

However, testing should be carried out at elevated temperatures (e.g. 800 °C).
