Modification of the surface and pores of poly(ethylene terephthalate) track membranes using N-isopropylacrylamide for an improvement of membrane performances

The track membranes based on poly(ethylene terephthalate) activated by low-temperature plasma were modified with the use of a solution of N-isopropylacrylamide in an organic solvent. The filtration efficiency of the modified membranes was higher by a factor of 2.5 than that of the original track membrane.
