    Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends حسب Al-Maadeed, M.

    منشور في 2010
    "…Thin films of a blend of 90, 75, 50 (wt/wt%) percentage of polyethylene oxide and polyvinyl alcohol were synthesized and irradiated with 5, 25, 50, 100 and 200 kGy. The presence of PVA leads to diffusion controlled mechanism where it decreases the crystallinity of PEO as restricted crystallization occurs.Low doses of 5 kGy cause crosslinking of the blends and increase the thermal stability. …"
