Dear Sir,

would you please specify the polymeric matrix. If it shows a dimensional stability under the BET conditions, the answer is may be yes depending on this porosity. If you are dealing with a cellular material, it is important to know if it is an open or closed cell  morphologies. I think additional details should be given. Regards

Besides the Abdelkader's answer, this is upon the polymer previous thermal history.

Surface area is directly related to the porosity of the material, and there are many cases for which the polymer can be porous. A surface area less than 1 m2/g is typical of a poorly porous polymer, and is not really surprising. For a higher accuracy in the measurement of so low value, I recommend using krypton instead of nitrogen as the probe molecule.

Dear All,

For Abdelkader's :  Polyvinylpyrrolidone is the matrix used for metal surface functionalization.

thanks for your informative comments...

I do agree with Sajjad comments

The specific surface area of a material should depend on its existing state. A polymer can form various microstructures, such as microspheres, porous structure, thin films.

Yes, a lot of polymers develop microporous  structure.

An insight can be found in

specific surface area is a general property for solids and can vary within a wide range. If your polymer is a solid you may try te get its SSA. Often SSA is measured for porous materials, but please remember that all the solid materials have some. In summary: your polymer have a specific surface area. Jacek

There are too many porous polymers, such as polymers of intrinsic porosity (PIMs), conjugated microporous polymers (CMPs), hypercrosslinked polymers (HCPs), covalent organic frameworks (COFs). They are all pure polymers. The highest reported SSA for porous polymer is now 6461 m2/g.

HI all. i am working with methacrylic polymer. i tried to measure the BET surface area using nitrogen. I got a value of 32 m2/g but the micropore radius is 0. does this mean still my polymer has some porosity and surface area or it is some error ? i could not find any specific literature on this aswell.
