The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing molder with different contents of Eu-ion doped Y2O3 nanophosphor powder. The influence of particle content on the optical and dynamic mechanical properties of the nanocomposites was investigated. The intensity of the luminescence emission spectra increased as the nanophosphor content in the composite increased. The results of dynamic mechanical analysis revealed that the storage modulus, loss modulus and glass transition temperature (Tg) of the polymer composites increased with increasing content of the nanophosphor powder. The microhardness data also confirmed that the hardness number increased with nanoparticles concentration in the PMMA nanocomposites. The obtained results revealed a relatively linear relationship between Tg and the Vickers hardness.
U okviru ovog rada prezentovano je istraživanje procesiranja i karakterizacije nanokompozitnog materijala poli(metil-metakrilat) (PMMA)-Y2O3 (Eu3+). Uzorci sa različitim sadržajem nanofosfora Y2O3 dopiranog sa Eu jonima procesirani su u laboratorijskom uređaju za umešavanje termoplastičnih polimera. Ispitivan je uticaj udela nanočestica na optička i dinamičko-mehanička svojstva kompozita. Intenzitet luminiscentnog emisionog spektra kompozita raste sa udelom nanofosfora. Rezultati DMA pokazuju da modul deponovane energije, modul gubitaka i temperatura transformacije rastu sa povećanjem udela nanočestica. Mikrotvrdoća kompozita takođe raste sa povećanjem udela nanočestica u kompozitu i pokazuje skoro linearnu zavisnost od temperature transformacije (Tg).
