Sažetak
Polyethylene terephthalate (PET) is a semicrystalline polymer which has good mechanical properties, chemical resistance, thermal stability, and the ability to be spun in the form of fibers. Therefore it is commonly used in packaging and fiber applications (beverage bottles, textiles etc), as well as in electronic industry (electrical parts, transparent substrate for flexible electrical devices such as OLED's, solar cells etc.). Due to the extensive and still-growing use of polymeric materials for technological applications of immense variety, the study of the stability and stabilization of polymers under irradiation environments has become an important issue. Here we present a study of proton irradiated PET and carbon based PET nanocomposites. PET-nanodimaond (ND) 1% by wt nanocomposites and PET –ND-graphene nanoplatelets (PET-ND-GnP) with 1% ND and 0.3 % graphene nanoplatelets have been produced by extrusion process. Samples of virgine PET polymer, PET-nanodiamond (PET-ND) and PET-ND-NGP) composite were irradiated in vacuum with a 3 MeV proton beam that was delivered by the 1.0 MV Tandetron accelerator at the Ruđeer Bošković Institute, Zagreb, Croatia.The effects of irradiation were monitored and analysed by vibrational infrared spectroscopy (FTIR), Raman spectroscopy and photoluminescence measurements. The results show improved irradiation resistance of nanocomposites in comparison to virgine PET films.
