“…Then, an in situ phase transformation from amorphous magnesium to lamellan brucite occurs, forming numerous nanoakes (step 5). 49 In the next step, the compound products about Mg-Fe-Ti pairs bridged by oxygen atoms were obtained via the recombination of lamellar brucite with amorphous titanium hydroxide and amorphous iron hydroxide, as follow:…”

“…During the formation of the network structure, defects will inevitably be formed, such as holes and incomplete coordination, resulting in the crystal layer being positively charged. Then, in Equation ( 6), in order to balance the positive charge carried by the laminate, CO 2− 3 in the solution intercalates into the interlayer through electrostatic interaction, hydrogen bonding and van der Waals force to balance the positive charge on the laminate and gradually forms the hydrotalc structure [32,33].…”

The traditional methods for preparing magnesium aluminum layered double hydrotalcite (Mg2Al-CO3LDHs) in industry include coprecipitation and hydrothermal methods. Both these methods have the disadvantages of high preparation cost and complicated water washing process. Using Mg(OH)2, Al(OH)3, and CO2 as raw materials in this work, the Mg2Al-CO3 LDHs are successfully prepared by mechanochemical method, which solves the shortcomings of traditional preparation method and realizes the conversion and utilization of CO2 resource. The prepared Mg2Al-CO3 LDHs are evaluated as a heat stabilizer in poly(vinyl chloride) (PVC). The result indicates that, when 2.4 phr Mg2Al-CO3 LDHs, 0.3 phr ZnSt2, and 0.3 phr of zinc acetylacetonate are added to the PVC, the thermal stability time of PVC can reach 190 min, which is better than PVC containing commercial Mg2Al-CO3 LDHs. Meanwhile, its processing performance is basically the same as the PVC containing commercial Mg2Al-CO3 LDHs.

Anodizing of aluminum and its alloys is widely used in various fields of science and technology. The process of modifying porous anodic aluminum oxide with ultradispersed diamond (UDD) particles to improve the mechanical characteristics of coatings requires additional study. UDD was modified by consistent heat treatment at 40 °C and 120 °C. The results of the UDD surface modification were controlled by IR spectroscopy. The surface state analysis was carried out using the PMT-3 microhardnessmeter, the SolverPro P47 atomic-force microscope (AFM), and the experimental probe-electrometry device. One of the ways to improve the mechanical characteristics of such coatings is the use of ultradispersed diamonds with respective pretreatment of their surface. The article presents the results of a study of the influence of additives of ultradispersed diamonds with different functional surface composition in an acid electrolyte to form coatings of porous anodic alumina on the surface of AMg-2 aluminum alloy substrates by electrochemical oxidation. An increase in the microhardness and wear resistance of anodic oxide coatings formed on aluminum alloy substrates after various post-growth heat treatments is noted. It is shown that using a combined method based on doping anodic alumina in the process of synthesis with modified ultradispersed diamonds and post-growth annealing of the coatings obtained in vacuum at T = 500 °C, it is possible to obtain a composite material that is 2 times higher in hardness and 3 times higher in wear resistance compared to the initial coating. The research results can be used to create a new generation of radiation-resistant heat-removing bases, nano and micromechanical devices, elements of passive and active electronics, high-quality parts for spacecraft and satellites on modern composite materials.
