Environmental concerns related to the implementation of circular economy has led to the development of new generations of materials. Interest in polymer composites reinforced with natural-organic/inorganic fillers is growing. Producers of polymer composites convert their production to optimize and replace traditional products with new ones with a high content of bio, recyclable materials, for sustainability and responsible actions. Research and industrial awareness are focused on ecological composites based on nat...

In this paper were obtained waste/polymeric nanocomposites - polyamide waste (PAW) and polystyrene (PS), compatibilized with maleic anhydride grafted polystyrene, and reinforced with carbon nanofibers (CF). PolyamideWaste / polystyrene (PAW / PS) composites are studied because both components are relatively cheap, with beneficial properties, and can be processed by injection. Compatibility of polymer and waste compounds can be achieved by adding a grafted copolymer, the segments of which have physical or chemical ...

The use of recycled polyethylene terephthalate (PETr) in new value-added products is problematic because, during reprocessing in the melt, it undergoes a number of chemical, mechanical, thermal and oxidative degradations, which leads to decreased intrinsic viscosity / molecular mass and implicitly to poor mechanical and thermal properties. In the literature, numerous approaches have focused on obtaining polymer blends using PETr in combination with other thermoplastic polymers. Unfortunately, such mixtures are inc...

Nanocomposites have been considered as a stimulating route for creating a new type of high performance material that combines the advantages of polymer and the nanoparticles. Polyamide is well known as an engineering thermoplastic material that is widely used in industrial applications for its good mechanical and thermal properties. The paper presents the study of the new nanostructured polymer composites from polyamide/oxidized graphite nanoparticles-PA/GO to manufacture, by injection, bearing seals, contact plat...
