*The iodine number (iodine adsorption) reflects a “not true” surface area, because it is affected by porosity, surface impurities, and surface oxidation. **The cetyltrimethyl ammonium bromide (CTAB) surface area analyzes the so-called external surface area which corresponds to the accessible surface area for an elastomer. ***BET (Brunauer, Emmett, and Teller) nitrogen adsorption surface area provides the “total” surface area including porosity. |
