Abstract
Organsko-anorganski hibridni materijali nova su vrsta nanostruktuiranih materijala koji ujedinjuju svojstva obiju faza od kojih se sastoje. Hibridni materijali s polimernom matricom mogu se nazvati i nanokompozitima kod kojih punilo nastaje unutar matrice, što omogućuje mnogo bolji doticaj među fazama. Polietilen tereftalat (PET) nanokompoziti dopirani ugljikovim nanočesticama pripremljeni su uz pomoć ekstrudera kako bi stvorili nanokompozit otporniji na zračenje. Provedena je studija, korištenjem diferencijalnog pretraživanja kalorimetrije (DSC), o strukturalnim promjenama nanokompozita izloženog protonskom zračenju. Pokazano je kako kompozitni materijali koji u sebi sadrže mali udio nanočestica grafena i nanodijamanta, pokazuju bolju strukturalnu stabilnost pri izlaganju radijaciji od čistog polietilen tereftalata. Nanopunila, naročito nanografen zaslužni su za stabilizaciju amorfne faze i povećane kristalnosti očuvajući pritom svojstva polimerne matrice izložene radijaciji.
Abstract (english)
Organic-inorganic hybrid materials are a new class of nanostructured materials, which unite the properties of both their constitutive phases. The polymer matrix hybrid materials can also be considered as nanocomposites where filler is formed inside the matrix, which significantly improves the interphase contact. Poly(ethylene terephthalate) nanocomposites reinforced with a small quantity of carbon nanostructures were prepared by simple melt blending in a twin-screw extruder in order to create polymer nanocomposites for application in high radiation environments. A study of structural modifications introduced by proton beam irradiation was conducted using Differential Scanning of Calorimetry (DSC). It was shown that the composite materials containing a small concentration of nanographen and nanodiamonds exhibit improved structural stability when compared with neat poly(ethylene terephthalate) exposed to proton irradiation under the same irradiation conditions. Nanofillers, particularly nano-graphene platelets stabilized the amorphous phase and increased the crystallinity of polymer matrix exposed to proton irradiation, preserving polymers physical - chemical properties.
