dc.description.abstractPET is used to produce a wide range of packaging for foods and beverages. Because oxygen can diffuse through it[1, 2, 3], PET is not suitable for fabrication of bottles for the storage of beer and red wine which are both degraded by oxygen. To store oxygen degradable foods for extended periods of time in PET packaging, oxygen diffusion through the PET must be prevented by incorporating a barrier layer or barrier polymer[1] into the PET matrix. We have begun a study of diffusion of light gases through samples of PET film that have been ion-implanted with aluminium and silicon ions to determine how dose level of these ions affects diffusion rate of helium and other gases through PET film. Polycarbonate (PC) is used to produce plastic products that have high toughness, high optical clarity and good resistance to UV degradation. However, PC sheet scratches easily because it is relatively soft. If PC sheet can be surface hardened to achieve scratch resistance similar to that of Perspex, it could be used to replace products, such as aircraft windows, currently fabricated from Perspex with tougher products fabricated from PC. Ion-implantation is one method that can be used to increase surface hardness and decrease surface wear rate [4]. © 2005 Australian Institute of Physics.en_AU
