Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...

The aim of this study was to fabricate transparent polymers with high thermal conductivities for applications in electronic packaging. Characteristics of the inorganic filler, calcium fluoride (CaF2), and the polymer matrix were examined, and thermal conductivity was measured using a thermal analyzer based on the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with CaF2 content. This study was the first to report ...

Silicone materials have high electrical and thermal insulation properties that are useful for engineering applications. In this study, vapour grown carbon nanofibers (VGCNF) were produced by two different methods and were added to silicone rubber to improve conductivity. A thermal constant analyser measured the thermal conductivities of the silicone and its composites using the transient plane source (TPS) method. Results showed that thermal conductivities of the roll-mill produced VGCNF/silicone ...

Intumescent paints protect steel structures from fires by creating insulative foams when heated above a critical temperature. This paper examines the fire resistance capabilities of phenyl silicone coatings in comparison to intumescent paints. A thermal constant analyzer measured the thermal conductivity of the silicone-based coatings using the transient plane source (TPS) technique. Results showed that the silicone/modifier coating consistently had lower thermal conductivities than the silicone coating. At heightened ...

The authors report the synthesis of a novel functionalized graphene sheet (FGS)/silicone porous nanocomposite with varying concentrations of FGS. The physical and thermal properties of the synthesized nanocomposites were studied in depth. SEM and TEM were used to elucidate the physical microstructure of the materials, and the transient plane source (TPS) technique was used to measure thermal conductivity. The nanocomposite showed an increased thermal conductivity as compared to the ...
