| Abstract: | Poly2-(N,N-dimethylamino)ethyl methacrylate](PDMAEMA) was prepared and grafted onto Fe3O4 magnetic nanoparticles encapsulated with SiO2(Fe3O4@SiO2) via combination of ATRP and Click reaction.So the magnetic nanoparticles grafted with PDMAEMA(Fe3O4@SiO2-g-PDMAEMA) on the sur-face were obtained.1H NMR and GPC tests were carried out to study the structure,molecular weight and polydispersity index(PDI) of alkynyl-capped PDMAEMA.TEM,FT-IR,TGA,DLS and Zeta potential tests were used to study the structures,morpho... |
