Nanokompozity na bázi montmorillonitu: příprava, struktura a vlastnosti

The field of polymer nanocomposites presents a class of multiphase materials, where at least one of the phases has at least one dimension less than 100 nm. Typical is low content of clay compared to conventional composites. The aim of this work is processing and characterization of a hybrid organic/inorganic system based on polymer and montmorillonite (MMT). As the polymer matrix, polyvinylchloride (PVC), polyolefin, polylactic acid (PLA) and polyamide 12 (PA12) were used. In addition to a brief introduction, the work contains another 4 chapters, which reflect the study of the mentioned polymers: PVC/MMT, Polyolefin/MMT, PLA/MMT and PA12/MMT nanocomposites. Futher one part of this work deals with intercalation and cointercalation process. Next, the prepared polymer compositions were characterized mainly from the viewpoint of mechanical properties, barrier properties and morphology. Furthermore, the influence of additives on the degradation of prepared nanocomposites was studied.
