Effect of Aluminum and Aluminum Nitride on Some Thermophysical Properties of Polyamide 6/High-Density Polyethylene and Styrene-Ethylene-Butadiene-Styrene/Polypropylene Blends

Abstract

The structure and physical-mechanical properties of non-compatibilized and compatibilized blends of polyethylene with polyamide 6 and polypropylene with styrene-ethylene-butadiene-styrene, containing heat-conducting modifiers (aluminum and aluminum nitride) in their composition, were studied. Data were obtained on the influence of the ratio of polymer components in the blend and the functionalization of one of them, as well as the type of heat-conducting filler, on the mechanical and dynamic mechanical properties of composites and their thermal conductivity. Using SEM, no selective distribution of aluminum and aluminum nitride in the two-component polymer matrix was found when composites were obtained by extrusion compounding. It was found that the reinforcing effect of the filler (change in shear modulus) is largely determined by the presence of a polar polymer in the blend matrix. Both heat-conducting modifiers affect the position of the glass transition temperature maxima of the polymers used. The prospect of creating an interpenetrating polymer network structure to achieve additional thermal conductivity gain while maintaining the proportion of the conductive modifier is demonstrated.
