(Phys.org) —Putting a stop to aging has now been made possible for highly porous polymer membranes whose efficiency in the separation of gases falls off fast when parts of their polymer chains rearrange, as so do their pores. In the journal Angewandte Chemie , a team of Australian and American researchers has now introduced a method for preventing this relaxation of the polymer chains: special porous particles made of an aromatic framework incorporate the polymer chains and hold them in their original position.
