Sažetak
Svojstva polimernih nanokompozita prevazilaze svojstva uobičajenih kompozitnih materijala zbog nanodimenzija i morfologije upotrebljenih punioca. Čestični punioci se uglavnom koriste u cilju poboljšnja mehaničkih i toplotnih svojstava polimera, kao i za modifikovanje električnih svojstava polimerne matrice i smanjenja cene koštanja. Organski modifikovane slojevite gline, kao što je montmorilonit, su između ostalih, najzastupljeniji punioci u upotrebi za poboljšanje svojstava polimernih matrica. Ovim preglednim radom biće prikazani najznačajniji i najviše proučavani glina-polimerni nanokompoziti, kao što su glina-poliolefini, glina-poliestar i glina-termoplastični poliuretan nanokompoziti. Takođe, svojstva biopolimer-glina nanokompozita biće predstavljena i razmatrana u radu.
Abstract
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved mechanical and thermal properties, as well as modified electrical properties and cost reduction. Organically modified layered clays, such asmontmorillonite, are among the most widely used fillers for the improvement of polymer matrices. Presented in this review are some of the most studied clay nanocomposites including clay-polyolefin, clay-polyester and clay-thermoplastic polyurethanenanocomposites. Additionally, the properties of clay-biopolymers nanocomposites will also be discussed.
