| Abstract [eng] |
The goal of this study was to create and investigate polyolefins and nanoclay composite, investigate their morphology and mechanical properties and also compare with microfilled polypropylene composite. The montmorillonite clay (MMT) was used as nanofiller. It was organically modified with quaternary ammonium salts of different structure and influence of modification on the morphology of MMT was investigated. Two polyolefins, such as linear low-density polyethylene (LLDPE) and propylene (PP), were used for investigation. Because LLDPE composites showed destruction of the microstructure, hence only PP was used for further investigation. The PP composites filled with MMT and shale ash (waste) were prepared and their morphology, mechanical properties have been investigated. It was shown that the morphology and mechanical properties of the PP composites are dependent on the filler nature and content. However, low adhesion interaction and the interface between filler and polymer matrix was observed in both MMT and shale ash addition cases. Therefore, in further studies it is necessary to compatibilize filler and polyolefin. The environmental impact of created PP composites was analysed and approximate life cost estimation of the PP composite products for packaging film and automotive panel was carried out. It was shown that the PP composites was profitable in use for the automotive panel comparing to conventional products. This project was investigated as required to project no: J05-LVPA-K-04-0045 and funded according to European Regional development, having period of implementation 2019-02-28 – 2021-02-27. |
