“…The effects of interfacial phonons transport are merged into this factor [238]. Although in macroscopic scale k is the controlling parameter for heat flux, it is strongly affected by h BD at nanoscale [266,267]. In this regard, interface plays a key role because of influence of factors such as lattice mismatch [256,268] and phonon scattering [267,269].…”

Composite materials and especially polymer composites are widely used in daily life and different industries due to their vastly different properties and design flexibility. It is known that the properties of the composites are strongly related to the properties of its constituents. However, it has been reported in many studies, experimentally and by simulations, that the characteristics of the composites do not follow the rule of mixing. It means that in addition to properties of the constituents, there are other parameters affecting the final physicochemical properties of composites. The interfacial interactions between fillers and host is one of the factors which can strongly affect the properties of the composite. In this review, we summarized the type of interactions between the constituents, their improvement techniques, interaction measurement methods, and the effects of interfacial interactions on thermal, mechanical, and electrical properties of composites.

Abstract. In this work liquid-crystalline polymer (LCP) nanocomposites reinforced with in-situ reduced graphene oxide are investigated. Graphene oxide (GO) was first synthesized by the Hummers method, and the kinetics of its thermal reduction was assessed. GO layers were then homogeneously dispersed in a thermotropic liquid crystalline polymer matrix (Vectran ® ), and an in-situ thermal reduction of GO into reduced graphene oxide (rGO) was performed. Even at low rGO amount, the resulting nanocomposites exhibited an enhancement of both the mechanical properties and the thermal stability. Improvements of the creep stability and of the thermo-mechanical behavior were also observed upon nanofiller incorporation. Furthermore, in-situ thermal reduction of the insulating GO into the more electrically conductive rGO led to an important surface resistivity decrease in the nanofilled samples.

We have demonstrated that at room temperature the electric polarization of a ferroelectric polymer, polyvinylidene fluoride (PVDF), in an artificial multiferroic structure can be controlled by applying an external magnetic field. We found that as the applied magnetic field is changed, the switching of electric polarization for the PVDF depends on the external magnetic field. We also noticed that both the electric coercivity and polarization of the PVDF polymer display hysteretic features as the applied magnetic field is changed. We found that the thickness of the PVDF layer has an effect on the magnetoelectric coupling strength in our samples. The coupling sensitivity increases as the PVDF layer thickness increases. It is possible to control the ferroelectric properties of a PVDF film by tuning the external magnetic field.
