To record UV spectrum for any sample (solid, liquid, thin film, polymer), we need reference material. Suppose if we analyze solid sample, we use Barium sulphate as reference material. For liquid samples, we use solvents as reference. But, for polymer films ??can anyone suggest me ?
In our previous article, we used PDMS film as our reference polymer.

Dear, in solids and films there are don't found to any solvent this is leading to don't make a comparison, but can make (base line) and (auto zero) to air and then put your sample and this method is applicable by material specialist.
You can use diffuse reflectance phenomenon for your film. For the DRS you can use Barium sulphate as reference before proceeding to test.
At the same time if your film is transparent and thin, you can use the transmittance mode also using air as reference. If you can control the thickness in precise manner for the various samples, you can use it for the quntification purpose also.
