AI Technical Summary

Technical Problem

Traditional Ti3C2Tx materials suffer from poor impedance matching and poor electromagnetic wave absorption performance, and their preparation process is complex and energy-intensive.

Method used

By preparing hollow spherical mixed-phase molybdenum disulfide@Ti3C2Tx composite material, using melamine-formaldehyde resin microspheres as templates and combining hydrothermal reaction to form a core-shell structure, the uniform growth of molybdenum disulfide on the Ti3C2Tx surface is achieved, forming heterogeneous interfaces and defects, which promotes electromagnetic wave loss.

Benefits of technology

It achieves lightweight, good impedance matching and wide-band electromagnetic wave absorption performance, and the fabrication process is simple, environmentally friendly and energy-efficient.
