Carboxylation-induced polyaniline morphology on surfaces of barium hexaferrite nano particles with enhanced microwave absorbing properties

Rong Ji et al.

Summary: Surface carboxylation of barium hexaferrite (BaM) provides activated points for the preferential growth of polyaniline (PANI) on BaM particles, leading to tuned morphology and improved complex permittivity. The convex rods and dendrite-like morphology of PANI activate electron transport, enhance interfacial polarization, and result in excellent microwave absorption due to enhanced electromagnetic wave dissipation and combination of losses.

Hollow Engineering to Co@N-Doped Carbon Nanocages via Synergistic Protecting-Etching Strategy for Ultrahigh Microwave Absorption

Panbo Liu et al.

Summary: A controlled synergistic protecting-etching strategy was proposed to construct hollow Co@N-doped carbon nanocages with uniform heterojunctions, addressing the shortcomings of using sacrificing templates or corrosive agents and exhibiting superior microwave absorption performance. The strategy not only provides inspiration for creating hollow void inside other MOFs crystals, but also broadens the candidates for lightweight and high-efficient microwave absorbers.

Preparation and characterization of nanocomposites of MoS2 nanoflowers and palygorskite nanofibers as lightweight microwave absorbers

Sheng Wang et al.

Summary: Clay minerals were effectively used to prevent aggregation of molybdenum disulfide nanosheets prepared with hydrothermal process, resulting in enhanced microwave absorption performance in the composites. Optimizing the content of clay minerals can further improve the absorption capabilities of the nanocomposites. The hierarchically structured clay mineral/molybdenum disulfide nanocomposites show potential as microwave absorbers for practical applications, with minimal reflection loss achieved at thin thickness.

Novel composites with a cross-linked polyaniline shell and oriented palygorskite as ideal microwave absorbers

Sheng Wang et al.

Summary: This paper investigates a new method of enhancing microwave absorption performance by mixing palygorskite with polyaniline. By introducing palygorskite, polyaniline aggregation can be effectively prevented, forming a cross-linked shell structure, and the shell thickness can be adjusted by controlling the palygorskite content to improve the materials' microwave absorption performance.
