摘要
Nanocomposites of poly(vinyl alcohol) (PVA)/ZnS and PVA/CdS was prepared by in situ hydrothermal reaction. The intensity of the PVA crystalline diffraction peaks decreased after 8 h of treatment at 120 °C. The diffraction of PVA crystal resulted from the strong intermolecular interaction between PVA chains through the intermolecular hydrogen bonding. The intensity of the diffraction peaks and also the size of the crystals were determined by the number of PVA chains packing together. After being composited with sulfides, the intensity of PVA diffraction peaks was further decreased. This is because the interactions of PVA with ZnS and CdS led to a decreased in the intermolecular interaction between the PVA chains and thus the degree of crystallinity.
