Abstract:
A mechanism of H(2) uptake, based on adsorption in the ordered cavities of nanoporous polymeric crystalline phases rather than on disordered amorphous polymeric surfaces, has been clearly established, for aerogels of syndiotactic polystyrene (s-PS) exhibiting the nanoporous δ phase. An ordered arrangement of the H(2) molecules is proven by FTIR spectra while the inclusion of H(2) is assessed by gravimetric measurements and molecular simulations.
