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: A root-like dendritic colloid was used to attach carbon nanotubes (CNTs) and titanium dioxide (TiO2) onto polyurethane (PU) foam to prepare high-performance moisture-electric generators (MEGs). The hybrid filler coated polyvinylidene difluoride (PVDF) dendritic colloids illustrates a filler-wrapped structure, which enables the filler to be in direct contact with water and enhances the interaction with water. By constructing a synergistic network between hydrophilic TiO2 and CNTs, the MEG demonstrated excellent performance, including high open-circuit voltage (0.51 V) and short-circuit current (47.3 μA). The power density and energy density reached 32.21 μW•cm^-3 and 15.97 μWh•cm^-3, respectively. This work provides a new strategy for moisture-electric generators.

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: Elastomer composites with temperature and strain-induced tunable EMI shielding effectiveness were successfully obtained by introducing temperature-sensitive microspheres (TSM) into PDMS/CNT mixture. The mechanism of temperature and strain-induced regulation on EMI shielding was investigated, showing that TSM particles could rearrange the CNT conductive network at specific temperature and strain levels. Temperature-induced regulation led to a decrease in EMI SE at 120°C, partially recovering at 150°C, while strain-induced regulation resulted in reduced EMI SE after 70% compression, partially recovering at 120°C.

Summary: An elastomer-semiconductor-elastomer stack structure is used to stretch a brittle n-type organic semiconductor by 50% and create fully stretchable complementary electronics. This development opens up possibilities for elastic integrated electronics in applications requiring interfaces with soft biological tissue. By integrating the brittle n-type semiconductor into the stack structure, microcrack formation and propagation are suppressed, and the semiconductor can be stretched without significant loss in performance. The stack structure also improves the long-term stability of the semiconductor in ambient environments, enabling the creation of elastic transistors, logic gates, photodetectors, and an active matrix deformable imager.

A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
