Summary: Ni-Co/PC composite is prepared by introducing metal Co element with Ni-MOF/PC as precursor. Then a series of Ni-Co bimetal/PC composites are prepared by polyaniline coating, oxidation reaction, and vulcanization reaction. It is found that vulcanization reaction was the best path for the electromagnetic wave absorption performance of the product. The minimum reflection loss (RLmin) of NiCo2S4/PC composite reaches - 67.81 dB at the sample thickness of 2.6 mm, and the maximum effective absorption bandwidth (EAB) reaches 6.16 GHz when the sample thickness is 2.1 mm. NiCo2S4/PC composite is an ideal electromagnetic wave absorber due to its excellent electrical conductivity, rich surface, and high attenuation capability.

Summary: Fused deposition modeling (FDM) is a common method for additive manufacturing of polymers, which is capable of producing complex parts quickly. This study examines the effect of three important process parameters - infill density, printing speed, and layer thickness - on the tensile properties of polylactic acid (PLA) specimens. The optimal parameters for maximum mechanical properties, minimum weight, and minimum printing time are determined using the Taguchi design of experiment method. The accuracy of the Taguchi method in predicting the mechanical properties of FDM-3D printed specimens is also assessed.

Summary: In this study, polyaniline (PANI)/epoxy composites were reinforced with PANI-M to enhance their electromagnetic wave absorption performance and mechanical properties. The synergistic effect of PANI fillers with different geometries led to a significant improvement in reflection loss at high frequencies, as well as the mechanical properties. Characterization of the PANI fillers prepared by different methods revealed their structural and morphological properties, providing guidance for the preparation of advanced engineered epoxy nanocomposites.

Summary: In this study, CoFe2O4/graphite-polypyrrole (PPy) metacomposites with negative dielectric constant were successfully prepared using the surface-initiated-polymerization method. The negative dielectric constant was regulated by changing the content of CoFe2O4/graphite. The crystal structure, chemical structure, and microstructure of the samples were characterized, and the magnetic properties were reported. This work provides guidance for the fabrication of polymer-based metacomposites with tunable negative dielectric constant.

Summary: The study investigated the bond strength of glass fiber reinforced polymer bars in sea-sand concrete, finding that substitution of sea sand and seawater for normal concrete had no significant impact on short-term bond strength. Additionally, increasing the concrete strength and polyethylene fiber content improved bond strength, while increasing the embedment length of the bar resulted in decreased bond strength.
