TEM images of PVNPAK-5-CdS (a) and PVNPAK-15-CdS (b) nanocomposites. The chemically hybridized CdS-PVNPAK nanocomposite samples were prepared by the sulfonation of PVNPAK, the preparation of the precursor PVNPAK(SO3)2Cd, and the in situ formation of CdS-PVNPAK nanocomposite (reprinted with permission from Ref. 161, Copyright 2008, American Chemical Society).
