In this paper the results of structural changes in ultra high molecular polyethylene (UHMWPE) upon gamma irradiation and storage in nitrogen environment are reported. Based on differential scanning calorimetry (DSC), wide ...
Effect of gamma irradiation on the microstructure and morphology of polyethylene oxide and polyvinyl alcohol blends
(
Trans Tech Publications
, 2010 , Conference Paper)
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 ...
