摘要：

A well-defined amphiphilic polystyrene-block-acrylic acid) (PSt-b-PAA) block copolymer to prepare a magnetic nanocomposite was synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. The synthesized PSt and PSt-bPAA copolymer was characterized using FTIR and H-1 NMR spectroscopies as well as GPC analysis. Afterwards, a PSt-b-PAA/Fe3O4 magnetic nanocomposite was fabricated through the incorporation of Fe3O4 nanoparticles (NPs) into the synthesized block copolymer. The morphology of the fabricated magnetic nanocomposite was observed using SEM and TEM. The SEM image revealed that the PSt-b-PAA/Fe3O4 magnetic nanocomposite had spherical morphology with the mean diameter of 100 nm, approximately. In addition, thermal properties of the synthesized polymers as well as the magnetic nanocomposite were studied using DSC and TGA analyses. The developed nanocomposite may be applied for enzyme immobilization and cell separation. (C) 2019 Sharif University of Technology. All rights reserved.
