Polipropilēna multifāzu kompozīcijas ar funkcionalizētām oglekļa nanocaurulītēm. Mileika L., darba vadītājs Dr.habil ķīm. Kaļķis V., bakalaura darbs, 35 lappuses, 23 attēli, 27 literatūras avoti, 1 pielikums. Latviešu valodā.
Darbā novērtēta polipropilēna ar piepotētu maleīnskābes anhidrīdu un difenola-a-dimetakrilāta modifikatoru ietekme uz ar funkcionalizētām oglekļa nanocaurulītēm bagātinātu polipropilēna kompozīciju fizikāli-mehāniskajām īpašībām. Izmantojot tādas ķīmiskās analīzes metodes kā rentgendifraktometrija, diferenciāli skenējošā kalorimetrija un infrasarkano staru spektroskopija, novērtēts, kā dažāds oglekļa nanocaurulīšu saturs polipropilēna kompozīcijā ietekmē tā virsmolekulāro struktūru. Noteikts, ka modifikatorus saturošām kompozīcijām ir paaugstinātas mehāniskās īpašības, pieaugot nanopildvielu saturam kompozīcijā.

Polypropylene multiphase composite materials with functionalized carbon nanotubes. Mileika L., supervisor Dr.habil Chem. Kaļķis V., Bachelor’s thesis, 35 pages, 23 figures, 27 literature references, 1 appendice. In Latvian. In the paper, the effect of maleic anhydride grafted polypropylene and bisphenol-a-dimethacrylate modifiers on the physico-mechanical properties of polypropylene compositions enriched by the functionalized carbon nanotubes was evaluated. Using chemical analysis techniques such as x-ray diffraction, differential scanning calorimetry and infrared spectroscopy, the effect of different content of carbon nanotubes in polypropylene compositions on the structure was investigated. It is eastimated that the compositions containing the modifiers showed an increase of mechanical properties, by increasing the content of nano filer content in compositions.
