“…It should also be noted that the spectra of the characteristic X-rays of the surface of copper polypropylene do not have peaks corresponding to oxygen. This allows us to conclude that there are no copper oxides in the coating, which was also noted by other researchers who received a copper coating in EDTA-Na2 solutions of chemical metallization [35]. The absence of oxides in the copper coating is also indicated by the diffraction pattern of copper polypropylene with no peaks on that can be attributed to copper oxides (СuO (35°, 38°, 61°) and Cu2O (29°, 36°, 61°)).…”

“…The next stage is the formation of a metal layer on the activated polypropylene surface as a result of the reduction of copper ions in chemical metallization solutions (Figure 2). Solutions of the following composition were used for metallization: CuSO 4 •5H 2 O brand "pure for analysis", EDTA-Na 2 (C 10 H 14 N 2 Na 2 O 8 •2H 2 O) brand "pure for analysis", NaOH brand "pure", formalin stabilized [33,35,37]. Concentrations of components of chemical metallization solutions were within (mmol/L): CuSO 4 •5H 2 O-48-144, EDTA-Na 2 -47-67, NaOH-250-560, formalin 366.…”

“…Obtaining metal-filled composite materials with high technological and operational properties requires the development of alternative technological solutions for their production. The technology of obtaining metal-filled polymer composites by the metallization of polymer raw materials with its subsequent processing by standard methods directly into products was used [33][34][35][36]. As a result, the process of combining the components is significantly facilitated and uniform distribution of the metal filler in the polymer matrix is ensured.…”

Metal-filled composites based on polypropylene waste have been successfully obtained with an injection molding method of metalized polymer raw materials. Using the model polymer, the peculiarities of the formation of the copper layer in solutions of chemical metallization on the polypropylene surface were investigated and the main factors influencing this process were established. The main influence on the rate of reduction of copper in solutions of chemical metallization has the concentration of copper sulfate, sodium hydroxide, and EDTA-Na2. It was shown that the efficiency of the copper plating process also strongly depends on polymer processing, which follows the activation. In case of the use of simple activation, it is not possible to obtain metalized raw materials with high efficiency. Additional processing of activated polymer raw materials is required to carry out the process with high efficiency. The amount of reduced copper on the polymer surface can be adjusted by changing the concentration of the components of the chemical metallization solution, as well as the degree of loading of the polymer raw material. Examination by electron scanning microscopy of the obtained metalized polypropylene showed that the copper coating on the polymer particles is formed with a high degree of surface coverage. The formed copper coating is free of copper oxides, which is confirmed by X-ray diffraction studies and analysis of the spectrum of characteristic X-rays. Metal-filled composites have been characterized by the effect of copper on mechanical and rheological (MFR) properties. The Differential Scanning Calorimetry (DSC) and Thermogravimetric (TG) methods show a certain effect of metal on the magnitude of thermal effects and the rate of weight loss.

“…This metal, reduced in the bulk of the solution, forms a precipitate and reduces the efficiency of copper deposition on the granules. Studies of activated polyethylene granules, which are obtained in the modes providing for low values of interaction of zinc particles with the polymer surface (a low speed of the ball mill and low activation time), show that in this case there is almost complete washing of the activator metal from the surface of the polyethylene granules and a reduction in copper ions in the bulk of the solution [ 55 ], not on the surface of the granules.…”

The research studied the feasibility of using copper-coated polyethylene granules as a basis for creating efficient heat storage systems. A technology for imparting catalytic properties to a polymer surface by the joint processing of polymer granules and an activator metal in a ball mill with their subsequent metallization in a chemical reducing solution is proposed. The efficiency of copper-coating a polyethylene surface is shown to be largely determined by the activation stage and the assumption regarding the mechanism of interaction of the activator metal with the polymer surface is made. To obtain different amounts of metal on the polyethylene granules, it is proposed that the method of remetallization is used. It was established that the rate of copper ion reduction depends on the number of previous coatings and is determined by the area of interaction of the metal-coated granules with the chemical reducing solution. The obtained metal-coated polyethylene granules were characterized in terms of the viability of using it as a phase transition material for a heat storage system. Using the developed installation that simulates the heat accumulator operation, it was shown that the efficiency of using metal-coated polyethylene granules to create heat storage systems is higher. The copper coating deposited on the polyethylene granules was studied using scanning electron microscopy and X-ray diffraction analysis.
