Surface Graft Polymerization of Polyethylene Terephthalate Nanofibers by Atom Transfer Radical Polymerization of N-isopropylacrylamide

polyethylene terephthalate(PET) nanofibers is prepared by electrospinning of polyethylene terephthalate solutions. PET nanofibers is treated with plasma. and the nanofiber surface be functionalized. The active agents in the surface of nanofiber act as a polymerization initiator in polymerization process . Then poly(N- isopropyl acrylamide)(PNIPAAm) was grafted on the surface of the nanofibers by atom transfer radical polymerization(ATRP) method. The surface nanofibers analyzaed by using scanning electron microscopy(SEM), ATR-FTIR and AFM.
