Study of mechanical, tribological and corrosion properties of epoxy composite coatings reinforced with recycled waste tire products.
The present work aims to evaluate the mechanical and anti-corrosion properties of epoxy coatings modified with recycled waste tires. In this study, epoxy coatings reinforced with ground tire rubber (GTR), devulcanized ground tire rubber (DGTR), pyrolytic black (PCB), and virgin carbon black (CB) particles were prepared and applied to a galvanized steel substrate. Micromechanical tests (nanohardness and microscratches) were used to measure the mechanical properties of the coatings. The tribological and corrosion performance of the coatings was evaluated using the ball-on-disk reciprocation test and the salt spray (5 wt % NaCl) corrosion test, respectively. Experimental results showed that recycled waste tires reinforced with composite coatings significantly improved wear resistance and anti-corrosion properties. In the study, the most notable results were a 77.7% increase in wear resistance in the DHTR-hardened coating. The highest corrosion resistance was obtained in the PCB-reinforced epoxy coating, no white rust was observed on the coating during the salt spray test (1000 hours), and the lowest blistering rate on the sample after the test was obtained as 8F.
It is a desire to give biodegradable polycaprolactone (PCL) luminescent properties while maintaining its biocompatibility in a possible way. To this end, biologically based luminescent furan-terminated hyperbranched polymers (HBPF) have been synthesized, and the branching degrees (DB) of HBPF vary from 0.47 to 0.55 depending on the change in the feed ratio of the monomers. All HBPFs have a low glass transition temperature (T
), excellent fluidity and bright yellow fluorescence in solution under ultraviolet (UV) light. Ultraviolet/visible (UV/Vis) and fluorescence spectra show that HBPFs exhibit cluster-induced emission (CIE) characteristics from non-traditional chromophores as concentration increases. In addition, materials based on PCL blended with HBPF are also being prepared. It was found that PCL-based mixtures emit white fluorescence, and the fluorescence intensity is affected by the content and DB of BPPF. The morphology of HBPFs/PCL shows that low abundance, high DB HBPFs are well distributed in PCL, which promotes electron transfer and group clustering, further enhancing fluorescent emission. Rheological analysis shows that HBPFs can reduce the viscosity of mixtures, indicating that HBPFs can play the role of flow modifiers in melt processing. The crystallization behavior shows that the degree of crystallization (X

For pure PCL is 60.3%, while 5% of the mass. HBPF-3/PCL is 71.9%). As a result, the modulus of PCL blends is improved. This kind of biocompatible mixtures with good complex properties and fluorescence characteristics is expected to be applied in the preparation of biomedical materials for non-invasive in situ detection.
The interaction between the reinforcing fillers and the elastomeric matrix determines the properties of the elastomeric nanocomposite. This study investigated the properties of nanocomposites based on ethylene-propylene-diene monomer (EPDM) rubber compounds with graphene oxide (GO) and reduced GO (rGO), as well as the effect of maleic anhydride (MAH) as a compatibilizer. Nanocomposites containing GO and rGO were prepared using a combination of solution mixing processes and torque rheometry. The formulation with rGO was found to reduce the optimum cure time by about 5%. The addition of MAH improved the mechanical properties of nanocomposites containing GO or rGO, with increases in elongation by 18% and 11% and tensile strength by 5% and 20%, respectively. The results showed good interactions between nanoparticles and EPDM compounds. However, despite the good physicochemical affinity of MAX and GO, their simultaneous presence in the EPDM compound does not have a synergistic effect on vulcanization and mechanical properties due to the excess amount of oxygen-containing functional groups present in the vulcanization process.

The evolution of the mesostructure (structuring dynamics) of natural rubber (NR) during maturation after various coagulation modes is little known, especially in wet coagulates. Thus, clots prepared from 3 different coagulation modes (sulfuric acid, formic acid and natural coagulation) with different maturation times (0, 2, 9, 16, 30 and 44 days) were studied. The mesostructure of NR samples was analyzed by SEC-MALS on wet coagulates, as well as on wet and dry pancakes. For wet coagulants coagulated with acids, only M
Did not undergo significant changes in the process of maturation. On the other hand, for wet coagula after natural coagulation, all mesostructural parameters changed significantly with maturation time. The results showed that structuring increased with maturation, forming larger microaggregates and a more structured macrogel within moist coagula after natural coagulation. This study showed that the creping process (comparison of wet coagulates and wet crepes) had only a moderate effect on the structuring of the NR samples. However, the drying process (comparison of wet and dry crepes) had an important effect on the structuring of the rubber, especially in natural coagulation and coagulation with formic acid. Coagulation with sulfuric acid, apparently, slowed down the phenomena associated with the structuring of microaggregates and macrogel.
For a nanocomposite, the interaction between nanoparticles (NPs) and the polymer matrix acting as a carrier plays a decisive role in the characteristics of the material in its intended application. Two UV-sensitive LFs (TiO
And ZnO) were chosen to study the effect of their interaction with chitin in the photocatalytic degradation of trimethoprim, which is a new pollutant. Chitin-NP composites have been characterized by structural, thermal, optical, and photoelectrochemical methods. It was shown that the immobilization of NPs in a chitin matrix has the same effect on both NPs, affecting the generation of their photocurrent and reducing the band gap, which makes it possible to use the visible light spectrum. The rate of degradation of trimethoprim under the influence of artificial sunlight and the chemical stability of chitin during repeated use were evaluated. Both composites can be used in a wide pH range, but an alkaline environment leads to a decrease in the efficiency of chitin:ZnO degradation. The photocatalysis reaction did not affect the chemical structure of chitin even after several cycles. As was observed for bare NPs, chitin:TiO

The decomposition efficiency of the composite with trimethoprim was higher than that of the chitin:ZnO nanocomposite. The chitin matrix made it possible to easily extract NPs from the treatment medium and process the material without loss of photocatalytic efficiency.
