γ-Irradiation Effects on Opto-Thermal and -Mechanical Properties of PET and PETG Fibers

摘要

Changes in opto-thermal and -mechanical properties of polyethylene terephthalate and glycol-modified polyethylene terephthalate (4 wt% of ethylene glycol) subjected to γ-irradiation at doses up to 30 Mrad and a dose rate of 138.8 rad/sec, were investigated by interferometry. Empirical formulae are suggested to correlate the opto-thermal and -mechanical properties of the γ-irradiated fibers with the applied dose. Microinterferograms and relationships between the parameters obtained are given for illustration.View full textDownload full textKeywordsγ-radiation dose, birefringence, copolyester fiber, interferometry, monopolyester, opto-mechanical, opto-thermal, refractive indices, structural parametersRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00914030902852286
