“…The volumetric method of studying the kinetics of metallization of the activated polymer surface is based on the peculiarity of the reduction of copper ions in solutions with the complexing agent EDTA-Na 2 . In such solutions, one mole of hydrogen is released per mole of reduced copper, the volume of which is measured [31,33]. To do this, the metallization was performed in an airtight container, which was connected to a measuring tube where water was displaced by gas (hydrogen).…”

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.

“…In the simplest case, the metal-filled polymer composite consists of metal particles that are evenly distributed in the polymer matrix [31]. The main disadvantage of this system is that at low concentrations of filler, they remain isolated from each other and do not contribute to the conductivity of the system.…”

International audienceThe concentration dependence of specific heat, electrical and thermal conductivities of nanocomposites based on high-density polyethylene (HDPE) filled with silver nanoparticles have been investigated. The composites filled with high filler content show high electrical and thermal conductivities. The dielectric relaxation spectroscopy was used to investigate the electrical properties in the studied systems. The scaling law of electrical percolation was used for an exact estimation of the percolation threshold (Pc). A low electrical percolation threshold was found in the investigated composites. The rule of mixture was sufficient for the prediction of the specific heat dependence of HDPEAg nanocomposites as a function of the weight filler content. The basic models of the thermal conductivity have a tendency to underestimate the measured values for the low and high filler concentrations

Many theoretical and semi-empirical approaches have been developed to determine the thermal conductivity of composites. These models give a better estimate for low filler concentrations. The work in this paper is aimed at the numerical and experimental study of the thermal behavior of polymer matrix composite materials (PSU and BaTiO3). The numerical resolution of the thermal heat transport for an elementary cell is based on the finite element technique. Special attention is paid to the effect of contact resistance, barium titanate fraction, and quenching temperature on the effective thermal conductivity and dynamic behavior of the composite. The obtained results show that the proposed numerical model agrees well with the experimental measurements and the analytical models of Hatta-Taya and Hashin-Shtrikman.
