Sub‐micrometer spheres of poly(glycidyl methacrylate) (PGMA) with a layer of poly(allylamine hydrochloride) (PAH) film are prepared by an easily controlled assembly method. The gold nanoparticles (Au NPs) exhibit a discontinuous structure on the PGMA@PAH particle surface, exhibiting a surface interaction between the PGMA spheres and the Au NPs. PAH not only modifies the surface of the PGMA particles but also affirmatively affects the crystallite of the PGMA particles. The real permittivity of the nanocomposite spheres is much higher than that of pure PGMA spheres. An improved thermal stability is observed in the nanocomposite spheres. The calculated bandgap (0.91 eV) of the nanocomposite spheres is observed to be lower than that (4.92 eV) of pure PGMA spheres.
