Summary: Conductive elastomers are highly desired in the electronics industry. This study focuses on the filler reinforcement, dielectric, mechanical, dynamic mechanical, and surface morphology properties of natural rubber/conductive carbon black composites. The results show improved DC conductivity and the formation of a continuous conductive network in the matrix. Theoretical models are used to predict mechanical and tensile properties, with the tensile strength of natural rubber increasing with the addition of conductive carbon black.

Summary: A novel pentafluorostyrene (PFS) interface modifier was used to improve the interfacial compatibility and enhance the dielectric properties of SiO2/PTFE composites, reducing the coefficient of thermal expansion (CTE). With a PFS content of 5 wt%, the CTE was reduced to 86 ppm/degrees C and the dielectric loss ranged from 0.71 x 10-3 to 1.53 x 10-3 at frequencies from 5 to 40 GHz. The PFS-modified composite exhibited stable dielectric properties across a temperature range of 0-150 degrees C, making it suitable for high-frequency and high-temperature applications.

Summary: Aluminum titanate-glass sintered composites with controlled thermal expansion coefficient were successfully prepared. A zero-thermal-expansion material could be obtained when the glass addition was 5-7 wt%. No chemical reaction between glass and Al2TiO5 was observed during sintering. The glassy phase at the grain boundary increased the thermal expansion coefficient and apparent density.

Summary: In this paper, a trifunctional epoxy resin (DPA-E) was prepared using diphenolic acid and epichlorohydrin as substitutes for traditional bisphenol A epoxy resin (DGEBA). The DPA-E showed similar properties to DGEBA except for curing temperature, glass transition temperature, and thermal expansion properties. With a low gel temperature and high glass transition temperature, DPA-E/DMDC has promising applications in aerospace and microelectronics.

Summary: The cation distribution, elastic properties, thermal expansion, and glass-like transitions were studied in single crystal ZnGa2O4 and Zn1-xMgxGa2O4. ZMGO exhibited greater disorder and differences in elastic properties, thermal expansion, and thermal elastic coefficients compared to ZGO and MGO. Glass-like transitions were observed in ZGO and ZMGO, revealing distinct behavior in response to temperature changes.

Summary: Understanding the thermo-elastic properties of cementitious composites with different saturation degrees is important for their durability in various hydraulic environments. This study proposes a micromechanical framework to predict these properties by considering the composition and structure of the composite at a microscopic scale. The framework proves to be reliable in accurately estimating the thermo-elastic properties of the composites under different saturation conditions.

Summary: This study focuses on the mechanical properties, thermal expansion performance, and thermal deformation performance of ethylene tetrafluoroethylene (ETFE) membrane at different temperatures. Experimental results provide information regarding the mechanical properties, glass transition temperature, coefficient of thermal expansion (CTE), and thermal deformation strain model of ETFE at various temperatures. The thermal deformation mechanism is proposed to be the sum of thermal expansion strain and elastoplastic strain caused by changes in the strain-stress relationship.

Summary: A new series of colorless polyimides (CPIs) with outstanding thermal and mechanical properties have been developed by introducing a novel dianhydride, 3FPODA. The addition of 3FPODA improved the glass transition temperatures, reduced the coefficient of thermal expansion, and enhanced the tensile strength, tensile modulus, and elongation at break of the CPIs. Furthermore, the active carbonyl group of 3FPODA also enhanced the adhesive properties of the CPIs.

Summary: Bamboo-like carbon nanotube reinforced poly(ether-ketone) nanocomposites were prepared via powder metallurgy route. Increasing CNT loading in PEK led to significant improvements in DC and AC electrical conductivities, with a percolation threshold between 1.3 vol.% and 1.95 vol.% CNT. The nanocomposites also showed increased thermal stability and thermal conductivity. The Helpin-Tsai model correlated well with the thermal conductivity of the nanocomposites.
