Description
Summary:A facile preparation of novel salt responsive spherical polymer brushes (SPB) consisting of a carbon spheres core and a shell of sodium polystyrene sulfonate (PSSNa) was described. The SPB were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The radius R of carbon spheres and hydrodynamic radius Rh of SPB were ca. 370 nm and 785 nm, respectively. The brushes had Mw of 393600 g/mol with polydispersity Mw/Mn of 1.58. Furthermore, the dependence of PSSNa brushes on ionic strength and pH was investigated.
