Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: Dielectric polymers with high energy density have attracted widespread attention in modern electronics and power systems. Improving the energy density of dielectric materials requires thermal treatment to modify the surface roughness of films and reduce local electric field distortion and charge injection. The thermal treated NBR/P(VDF-HFP) films exhibit higher breakdown strength and dielectric permittivity.

Summary: This study focuses on the functionalization and distribution of conductive fillers, as well as the interfacial compatibilization of polymer blends, in order to improve the electrical conductivity and electromagnetic interference shielding efficiency of composites. By modifying the carbon nanotubes (CNTs) with an ionic liquid copolymer and controlling the blending process, selective localization of CNTs at the interphase and the formation of effective conductive networks at the interface were achieved. This resulted in a significant increase in electrical conductivity and a maximum EMI shielding efficiency of 41 dB for the PLA/PCL/PIL/CNT composites.

Summary: This study investigates the piezoresistive and mechanical behaviors of multiwalled carbon nanotube (MWCNT) /polyamide (PA12) lattice composites processed via selective laser sintering (SLS). The results show that increasing the MWCNT loading significantly increases the porosity of the sintered composites, resulting in decreased elastic stiffness and strength but enhanced piezoresistive characteristics. Furthermore, the composites exhibit different energy absorption and strain sensing characteristics under different loadings.

Summary: Ceramic/polymer dielectric functional composites, specifically the (Ba0.6Sr0.4)TiO3/PEEK (BST/PEEK) composites, were prepared with high frequency stability of the dielectric constant and low dielectric loss via cold-pressing sintering. The optimal properties of the BST/PEEK composites were achieved at a BST concentration of 40 vol% and sintered at 360°C for 1 hour, showing a permittivity of 23, a loss of 0.0065, F(x) <5%, and a dielectric tunability of 11.9%. The study provides insight for developing new composites with low loss and high frequency stability.

Summary: This study presents a nature-inspired interface strategy to fabricate high-performance and low-cost fiber-reinforced composites. By coating a heterostructural montmorillonite-multiwalled carbon nanotube (Mt-MWCNT) hybrid on the surface of glass fibers, a nacre-like interface layer is formed, improving the strength and toughness of the glass fiber/ epoxy composites. The enhanced dispersion and strong bonding of the Mt-MWCNT hybrids contribute to the improvement in interlaminar shear strength, work of break, storage modulus, and thermal stability of the resulting composites.
