Positron annihilation and ion beam analysis of ion-bombardment-induced hydrogen release and oxidation of ultra high molecular weight polyethylene
(
Elsevier
, 2007 , Article)
Ultra high molecular weight polyethylene was bombarded with He+ and Ar+ ions to fluences ranging from 1013 to 2×1016 ions/cm2. Rutherford backscattering and nuclear reaction analysis were applied to study mechanism of ...
Positron annihilation studies of the effect of gamma irradiation dose in polymers
(
Elsevier Ltd
, 2003 , Conference Paper)
Positron annihilation lifetime (PAL) technique has been applied to study the effect of gamma irradiation dose on the structure of low-density polyethylene and polystyrene. The positron annihilation lifetime measurements ...
Positron annihilation lifetime study of helium ions implanted polyethylene blends
(
Trans Tech Publications Ltd
, 2004 , Conference Paper)
The structural defects of linear low density polyethylene (LLDPE) and high density polyethylene (HOPE) blends implanted with helium ions were investigated using position annihilation lifetime (PAL) technique. The positron ...
Electron irradiated low-density polyethylene studied by positron annihilation lifetime spectroscopy
(
Elsevier Ltd
, 2003 , Conference Paper)
A study of the degree and rate of cross-linking of low-density polyethylene (LDPE) as a result of irradiation by high-energy electron beam has been performed using positron annihilation lifetime (PAL) technique. The PAL ...
