“…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.

Novel Ni/pHEMA-gr-PVP Composites Obtained by Polymerization with Simultaneous Metal Deposition: Structure and Properties

The synthesis and study of metal-containing hydrogels, particularly those filled with nickel nanoparticles, is currently of interest to many researchers. This paper presents the results of an investigation of the structure and properties of Ni(0)-filled composites on the basis of 2-hydroxyethylmethacrylate copolymers (HEMA) with polyvinylpyrrolidone (PVP) and their hydrogels. The authors of the article are the first who propose the method to produce these materials by combining the processes of polymer matrix synthesis and a reduction of Ni2+ ions. Synthesis is carried out in one stage without complicated equipment and is technologically simple. It is determined by thermometric research that the temperature conditions required for the chemical reduction of Ni2+ are achieved due to the heat released during the exothermic reaction of HEMA polymerization in the presence of PVP. With the help of Fourier transform infrared analysis, and thermogravimetric and differential-thermal analysis, the formation of a crosslinked graft copolymer based on HEMA and PVP was confirmed, and its structural parameters, including the efficiency of PVP grafting, PVP content in the copolymer, and the molecular weight of the interstitial fragment of the polymer network, were investigated. The results obtained with scanning electron microscopy revealed that the size of the Ni(0) particles is about 500 nm. X-ray structural analysis of the composites obtained confirmed the existence of metal nickel particles. The strength, elastic, sorption, electrical, and magnetic properties of the obtained composites in the solid (dry) and elastic (swollen) physical states, depending on the composition of the copolymer and the content of the metal filler, have been investigated.

The basic technological parameters of the preparation of nickel-filled hydrogel materials based on copolymers of polyvinylpyrrolidone with 2-hydroxyethyl methacrylate by the method of polymerization with simultaneous recovery of metal ions were considered. It was established by volumetric method that the process of chemical reduction of nickel ions at pH 7.5-8 is characterized by a high rate and a small induction period at a temperature of 60-70 0 C. The presence of polyvinylpyrrolidone was found to reduce the duration of the induction period and increase the rate of the reduction reaction. The duration of the induction period is 14 minutes when the content of polyvinylpyrrolidone in solution is 200 g/L. The kinetics of heat release during copolymerization of 2-hydroxyethyl methacrylate with polyvinylpyrrolidone initiated by benzoyl peroxide was investigated by a thermometric method. It was established that the exothermic effect of the polymerization can be used to ensure the required temperature conditions for Ni 2+ reduction. The versatile effect of the composition of the original polymer-monomer composition on the basic parameters of the exothermic process of copolymerization has been experimentally shown. The diversified effect of the composition of the initial polymer-monomer composition on the parameters of the exothermicity of the copolymerization was experimentally determined. The simplexlattice planning method was used to optimize the formula of polymer-monomer composition. The obtained regression equations allow establishing analytical dependences of the parameters of exothermic processes on the technological conditions of the reduction of Ni 2+ ions and the formula of the polymer-monomer composition.
