“…To calculate the theoretical values of the thermal conductivity of polymer composites, researchers often use the Maxwell model [ 34 ]: λ c = λ m × (λ f + 2 × λ m − 2 × v f × (λ m − λ f ))/(λ f + 2 × λ m + v f × (λ m − λ f )). …”

The results of studying the effect of particles of few-layer graphene (FLG) synthesized by self-propagating high-temperature synthesis (SHS) on the complex of strength and thermo physical properties of polymer composite products obtained by digital light processing (DLP) 3D printing are presented. It was discovered to achieve an increase in thermophysical and strength parameters of polymers modified by FLG compared with samples made on the unmodified base resin. This result was achieved due to low defectiveness, namely the absence of Stone–Wales defects in the structure of FLG due to the homogeneous distribution of FLG over the volume of the polymer in the form of highly dispersed aggregates. It was possible to increase hardness by 120%, bending strength by 102%, Charpy impact strength by 205%, and thermal conductivity at 25 °C by 572% at concentrations of few-layer graphene of no more than 2 wt. %.

“…However, the Maxwell model assumes that the filler particles are spherical in shape. Therefore, to account for the thin sheets shape of the filler particles, the Maxwell–Burger–Eiken model is used 52 where L = λ1+2*λ23*λ1 is the coefficient taking into account, the thin sheets shape of the filler particles.…”

This paper presents the results of a study of the strength and thermophysical properties of the composite material graphene nanoplatelets (GNP)–nitrile butadiene rubber (NBR) (GNP@NBR). High-quality GNP were massively produced by self-propagating high-temperature synthesis (SHS) method. It was found that the introduction of GNP in concentrations up to 6 wt.% leads to an increase in tensile strength up to 62%, resistance to tearing up to 64% thermal conductivity up to 2. The use of GNP allowed increasing the maximum operating temperature of the NBR to 125℃. Also, GNP@NBR composite showed an exceptional improvement in antifriction properties – it drops more than twice the coefficient of friction on steel under loads to 500 Newtons.

The results of studying the effect of particles of few-layer graphene (FLG) synthesized by self-propagating high-temperature synthesis (SHS) on the complex of strength and thermo physical properties of polymer composite products obtained by DLP 3D printing are presented. It has been discovered to achieve an increase in thermo physical and strength parameters of polymers modified by FLG compared with samples made on the unmodified base resin. This result was achieved due to low defectiveness, namely the absence of Stone-Wales defects in the structure of FLG due to the homogeneous distribution of FLG over the volume of the polymer in the form of highly dispersed aggregates.
