Summary: In this study, hollow glass microbeads were used as fillers and modified epoxy resin was used as the matrix to prepare composite coatings with improved heat resistance and mechanical properties. The thermal stability of the composites was found to increase with the increase in filler content, and the low density and high sphericity of the hollow glass microbeads facilitated uniform dispersion in the polymer matrix.

Summary: With the development of electronics, there is a growing demand for high-performance heat-dissipation materials in electronic devices. This study utilizes continuous carbon fibers as fillers in thermal conductive silicone rubber (SR) to enhance its thermal conductivity. The fibers are uniformly distributed and aligned parallel to serve as thermal conductive pathways. The addition of boron nitride (BN) further improves the thermal conductivity of SR. Moreover, applying BN/SR as a coating increases the volume resistivity while maintaining the thermal conductivity of the composite material.

Summary: In this study, ultrathin graphene nanosheet-based foams were successfully synthesized for highly integrated electronic devices in the 5G/6G era. The texture, defects, graphitization, EM parameters, EMI SE, and thermal conductivity of the graphene foams were modulated by calcination temperature and PEG 20000/NaCl mass ratio. The optimized EMI SE and thermal conductivity were achieved at a calcination temperature of 800 degrees C and a PEG 20000/NaCl mass ratio of 0.530. These graphene foams exhibited excellent EMI shielding effectiveness, high thermal conductivity, and lightweight structure for advanced electronic packaging applications.

Summary: In this study, an improved random aggregate adding method was used to develop a microscopic model of glazed hollow bead insulation concrete (GHBIC), and the model's effectiveness was verified through a test. The heat transfer performance of GHBIC was studied, showing that the glazed hollow bead effectively blocked the heat flow channel of GHBIC. A mathematical model for the thermal conductivity of GHBIC was established, considering the fineness of glazed hollow bead.

Summary: The ablative properties of epoxy modified silicone rubber composites filled with zinc borate (ZB) and aluminum hypophosphite (AHP) were improved by forming a dense char layer. The optimal ablative performance is achieved when the concentration of ZB and AHP is 10 and 5 phr, respectively. The structure and composition of the char layer were analyzed using various techniques.
