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)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 ...
