AFM has been proved to be a rapid method of assessing membrane–solute interactions (fouling) of membranes under process conditions. The interactions of developmental membranes (SPEEK/PSU and PSU) with different solutes have been directly measured and linked to process performance. Correlation of the

Sulfonated poly(ether ether ketone) (SPEEK), a strong polyelectrolyte, was investigated as an additive in polysulfone (PSU)/SPEEK/N-methyl-2-pyrrolidinone (NMP) systems. Membrane characterisation was carried out using filtration studies and by atomic force microscopy (AFM). The effect of SPEEK in th
