The modification of polymer track membranes from polyethylene terephtalate
(PET) and polypropylene (PP) was performed by radiation-induced graft polym
erization of thermosensitive poly-N-isopropylacrylamide (poly-NIPAAM). The
opening and closing of the pores was controlled by temperature and studied
by the electric conductivity and water flow methods. The structure of the g
rafted membranes was investigated by scanning electron and atomic force mic
