title: Splaying hyperthin polyelectrolyte multilayers to increase their gas permeability.
abstract: The concept of splayed, hyperthin polyelectrolyte multilayers (PEMs) is introduced in which a bulky, hydrophilic and charged pendant group is used to increase the gas permeability of a PEM without reducing its permeation selectivity. Proof of principle studies are reported using nm-thick PEMs made from poly(sodium 4-styrene sulfonate) () and poly(allylamine hydrochloride) () bearing bulky cobaltocenium ions.
