Summary: The study found that 1 and 2 wt.% of salvia filler can improve the physicomechanical properties of PUR composites, while 5 wt.% of filler may result in a less uniform structure. Additionally, the modification of salvia filler with MMT improved the interphase compatibility between filler surface and PUR matrix, leading to enhanced performances of the composites.

Summary: Thermally conductive polyvinylidene fluoride (PVDF) composites were prepared by incorporating carbon fibers (CFs) with different lengths. The addition of CFs significantly improved the thermal conductivity of PVDF composites, with the highest thermal conductivity achieved when shorter CFs were used. CFs also enhanced the mechanical properties and glass transition temperature of PVDF. This work provides a new method for developing thermally conductive and mechanically stable polymer composites.

Summary: This study investigated the thermal diffusivity and conductivity of dense and porous binary composites with insulating and conducting phases across the entire composition range. Experimental evaluation was performed on MoSi2 particles embedded in YPSZ through spark plasma sintering (SPS). Thermal diffusivity was measured using Flash Thermography (FT) and Laser Flash Analysis (LFA), and the thermal conductivity was determined based on heat capacity and density measurements. The volume fraction of the conducting phase was determined through X-ray map image analysis using scanning electron microscopy (SEM), while X-ray diffractometry (XRD) with Rietveld refinement determined the phases present and their density. The thermal diffusivity increased with increasing volume fraction of MoSi2. Porosity reduced the thermal diffusivity, but the effect diminished with high volume fractions of MoSi2. Modelling captured the thermal diffusivity as a function of MoSi2 volume fraction in YPSZ composites, accounting for porosity and the percolation of the conductive phase.

Summary: A novel epoxy composite with high thermal conductivity and greatly enhanced flame retardancy was developed by constructing an integrated three-dimensional (3D) network structure based on boron nitride (BN), talc, and ammonium polyphosphate (APP). The composite exhibited significantly improved thermal conductivity and flame resistance compared to pure epoxy and samples with random filler distribution. Different combinations of fillers were also evaluated for their effects on the flame resistance of the epoxy composite.
