Dear Hamza Khalid, they are not the same. Polypropylene is a polyolefinic polymer characterized by a C-C main chain and a CH3 side group. On the other hand, polypropylene glycol is characterized by a C-C-O main chain repeating unit and CH3 side group.
Glycols polymers are effectively used as EMI shielding films as composites with other additives such as graphene oxides. My Regards
So in case of glycols some additives are necessary that may be any other polymer i.e dissolving glycols in polymer matrix??
Bcz they need to to casted into films by solution blending so a rubbery additive must be necessary in this case i.e polyethylene glycol/PMMA composite??
I Saïd glycols polymers not simple glycols. By simple google search you end up with many documents, where for example graphene oxide is added to polyethylene glycol for EMI shielding. Worth to undertand is conductivity is the first criterium to be considered in such a field, best of luck.
