Sphere-shaped and monodispersed copper nanoparticle-coated poly(styrene-co-sulfonic acid) (Cu/PS) hybrid nanomaterials had been successfully synthesized by a green and facile synthesis method, in which chlorosulfonic acid and glucose were used as a sulfonating agent of polymer beads and a reducing agent. SEM and X.RD measurements revealed that the Cu/PS hybrid materials were successfully acquired. Moreover, the size and shape of Cu nanoparticles of the Cu/PS hybrid materials (i.e., Cu/PS-1, Cu/PS-2 and Cu/PS-3 hybrid materials) depended on the sulfonating agent and reducing agent concentration...
