Compositional transformations in ion implanted polymers
A.M., Abdul-Kader; Turos, A.; Grambole, D.; Jagielski, J.; Piątkowska, A.; Madi, N.K.; Al-Maadeed, M.... more authors ... less authors ( Elsevier , 2005 , Conference Paper)Changes of surface layer composition produced by ion bombardment of polyethylene and polypropylene samples were studied. These materials are under consideration for load bearing surfaces in biological and technical ... -
The effects of ion bombardment of ultra-high molecular weight polyethylene
A., Turos; Abdul-Kader, A.M.; Grambole, D.; Jagielski, J.; Piątkowska, A.; Madi, N.K.; Al-Maadeed, M.... more authors ... less authors ( Elsevier , 2006 , Article)Ion bombardment is a suitable tool to improve tribological properties of polymers. In this study UHMWPE samples were bombarded with 130keV He ions to the fluences ranging from 1×1014 to 2×1016cm−2. RBS and NRA techniques ... -
Surface layer modification of ion bombarded HDPE
D., Bielinski; Lipinski, P.; Slusarski, L.; Grams, J.; Paryjczak, T.; Jagielski, J.; Turos, A.; Madi, N.K.... more authors ... less authors ( Elsevier , 2004 , Article)Press-moulded, high density polyethylene (HDPE) samples were subjected to ion bombardment and effects of the modification studied. He+ ions of energy 100 keV or Ar+ ions of energy 130 keV were applied in the range of dose ... -
Temperature and electric field effects on the dielectric dispersion of modified polyvinyl chloride
M.E., Bassiouni; Al-Shamy, F.; Madi, N.K.; Kassem, M.E. ( Elsevier , 2003 , Article)The effect of electric field on the dielectric dispersion of modified polyvinyl chloride (PVC) has been investigated. The applied direct current (DC) field strength was ranging from 0 to 104 V cm−1. The complex permitivity ...
