“…When observing this phenomenon, it was found that the obtained peaks came from the introduced compatibilizer, which was polyethylene grafted with maleic anhydride. The obtained band corresponds to the literature values for PE (2θ = 21.7°) [ 41 ].…”

“…On the WAXS curves of the obtained composites, a wide peak with a 2θ value of about 18° was observed, which is a characteristic result for the arrangement of the PC/ABS polymer [ 41 ]. In addition, the PC/ABS/3%B composite is characterized by small 2θ peaks of approximately 2.9° and 6.2°, while the analysis of the results obtained for fillers revealed that the filler B has a band at 5°.…”

As part of this work, polymer composites based on polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) were obtained and used in 3D printing technology, particularly Melted Extrusion Modeling (MEM) technology. The influence of selected fillers on the properties of the obtained composites was investigated. For this purpose, modified fillers such as silica modified with alumina, bentonite modified with a quaternary ammonium salt, and hybrid lignin/silicon dioxide filler were introduced into the PC/ABS matrix. In the first part of this work, polymer blends and their composites containing 1.5–3 wt. of the filler were used to obtain the filament using the proprietary technological line. Moldings for testing the performance properties were obtained using additive manufacturing techniques and injection molding. In the subsequent part of this work, rheological properties (mass flow rate (MFR) and viscosity curves) and mechanical properties (Rockwell hardness and static tensile strength with Young’s modulus) were examined. The structures of the obtained composites were also determined by scanning electron microscopy (SEM/EDS). The obtained results confirmed the results obtained from a wide-angle X-ray scattering analysis (WAXS). In turn, the physicochemical properties were characterized on the basis of the results of tests using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Based on the obtained results, it was found that the introduced modified additives had a significant impact on the processing and functional properties of the tested composites.

In this paper, blends of recycled polyethylene terephthalate (r-PET) and high-density polyethylene (HDPE) with and without a compatibilizer were prepared using a Brabender Haake Rheocord at 270°C and 32rpm. Ethylene vinyl acetate was chosen as the compatibilizer and its proportion was set to 5, 7, and 10 wt%. The thermal properties and crystallization behavior were determined by Differential Scanning Calorimetry (DSC). Micromechanical properties were also investigated using a Vickers microindentation tester. The DSC analysis indicates that the melting temperature of r-PET and HDPE in all the blends, compatibilized and uncompatibilized, remains constant and almost the same as those of the pure component. On the other hand, it is shown that the degree of crystallinity of HDPE in the blends calculated by DSC depends on the composition of the polymeric mixture. However, the Hardness (H) decreases with increasing r-PET content until 50/50 composition of r-PET/HDPE is reached, whereas for larger r-PET content values, H increases. The same trend was obtained with the addition of the compatibilizer.

“…Thus, in preceding investigations we have examined the influence of a compatibilizer on the morphology and microhardness of iPP/PET /Mmt 15 and iPP/HDPE/compatibilizers and clay. 16 Therefore, our contribution aims to improve the compatibility of hybrid composite materials consisting of a mixture of two initially incompatible polyolefin (PP/HDPE) and particulate nano-filler (CaCO 3 ) treated on the surface with two coupling agents, namely: (organosilane sold under the name Silquest A-172 and organozirconate marketed under the reference Ken-React NZ-12). The aim is to study the relationships between morphology and the mechanical and thermal properties of composites by means of microhardness indentation in combination with DSC and WAXS.…”

Blends of polypropylene and high density polyethylene (PP/HDPE) were prepared in the presence of particulate nano-filler calcium carbonate (CaCO 3) treated on the surface with two coupling agents, namely: (organosilane Silquest A-172 and organozirconate Ken-React NZ-12). The structure and properties of the modified blends were investigated by means of differential scanning calorimetry (DSC), wideangle X-ray scattering (WAXS), and macro-and micro-mechanical measurements. The crystallinity of the modified samples (PP, HDPE and their blends) does not seem to be so much affected by the presence of the filler. The study of thermal properties by differential calorimetric analysis (DSC) indicates that the melting temperature varies slightly with the filler content. The presence of coupling agents promotes the development of spherulites by causing a slight increase in crystallinity levels. The addition of the treated or untreated filler to the mixtures increases impact strength and Young's modulus. The micromechanical results show that the microhardness of the PP/HDPE blends notably increases with the PP content. The micromechanical properties of the modified blends only improve slightly as a consequence of the addition of the treated filler with the coupling agents.
