Effect of Irradiation on Crystallinity and Mechanical Properties of Ultrahigh-Molecular-Weight Polyethylene
摘要:
Ultrahigh-molecular-weight polyethylene (UHlMWPE) has been irradiated (0-40 Mrad) with a Co60 source at room temperature under vacuum.Their crystallinity has been investigated by DSC and SAXS A significant increase of heat of fusion can be seen at low irradiation doses, which is attributed to crystallization caused by chain scission during the process of irradiation.It is also observed that thickness of lamellae changes with irradiation dose.Young's modulus has been improved significantly after irradiation at low doses.
