Summary: Improving the tolerance of flexible polymers to extreme temperatures and electrical fields is crucial for the development of advanced electrical and electronic systems. This study focuses on blending a molecular semiconductor (ITIC) into a promising polymer (PEI) to inhibit carrier movement and improve high-temperature charging and discharging efficiency. By changing the concentration and position of the molecular semiconductor using electrospinning technology, the researchers were able to optimize the trap density and trap layer location, resulting in a composite dielectric with optimal high-temperature energy storage properties. The study also proposes a mechanism based on Mott and Gurney's law to explain the effect of trap parameters on leakage current, providing a new structural design idea for regulating the dielectric properties of all-organic dielectrics.

Summary: This paper investigates the effects of adding alumina nanofibers on the mechanical properties of epoxy resin. It is found that the addition of alumina nanofibers can increase the flexural strength of the resin, but exceeding a certain threshold leads to a decrease in strength. Furthermore, adding nanofibers lowers the resin's glass transition temperature, indicating a decrease in molecular weight.

Summary: A defined three-dimensional nanoparticle assembly within unit cells can be achieved by linking nanoparticles to block copolymers. The study shows that the block length ratio and interfacial curvature are crucial factors determining lattice type, with even a one percent volume fraction enough to destabilize the structure and favor the formation of highly curved interfaces. This research paves the way for functional 3D-nanocomposites with nanoparticles located on specific matrix positions.

Summary: Using a sandwich-structured composite film with biaxially oriented polyethylene terephthalate (BOPET) as the outer layers, the conduction loss and breakdown path propagation in dielectric films under high temperature and electric field conditions can be effectively inhibited. The addition of boron nitride nanosheets (BNNSs) further improves the breakdown strength and reduces conduction loss. The optimized composite film exhibits excellent energy storage performances at both room temperature and high temperature.

Summary: Polyacrylamide-based hydrogels were strengthened using titanium oxide (TiO2) and carbon nanotubes (CNTs) alone and combined in a matrix, resulting in improved mechanical properties and puncture resistance. The synergistic effect of TiO2 and CNT nanoparticles with PAM led to high compressive strength and elastic modulus, as well as significant self-healing and cytocompatibility. The stability and structural features of the PAM-TiO2-CNT composite were analyzed using density functional theory (DFT), showing promising potential for cartilage repair applications.

Summary: We report a PANI-HA hydrogel that combines rigid conducting polymer with flexible HA. The supramolecular assembly of PANI and HA via boronic acid bonds yields PANI-HA hydrogel with unique microstructure, electrical conductivity and hydrophilicity, showing excellent supercapacitor performance and electrochemical sensing for IgG. The PANI-HA hydrogel-based electrode exhibits high specific capacitance (369 F g(-1)) and good cycling stability (85% capacity retention after 1000 charge-discharge cycles). It can also be used as an electrochemical biosensor for IgG detection with good sensitivity, wide detection range, and low detection limit.
