Luminescence probe studies of ionomers-II Steady-state measurements from sulphonated polyethylene and teflon membranes.
Luminescence probe studies of sulphonated Teflon and sulphonated polyethylene ionomer membranes are described. These studies have shown that the micropolarities of the ionic clusters within these ionomers are quite dynamic, varying with the nature of the chain material and the membrane water content. These studies also suggest that polymer chain material intrudes into the ionic cluster phase.
