AI Technical Summary

Technical Problem

Cellulose-based fabrics are flammable, and traditional flame retardants have limited functionality, failing to provide proactive fire warnings and struggling to balance thermal comfort with thermal management functions.

Method used

A layer-by-layer self-assembled composite functional layer of modified MXene and imidazole-based MOF is constructed on the surface of cellulose fabric. By utilizing the conductive framework and physical barrier of modified MXene and the catalytic char formation sites of imidazole-based MOF, flame retardant, fire warning and electro/photothermal management functions are realized.

Benefits of technology

It enables rapid early warning of fires in the early stages of a fire, provides efficient thermal management performance, remains stable at high temperatures, and possesses excellent flame retardant properties and thermal stability.

Abstract

This invention provides a multifunctional smart fabric, its preparation method, and its applications. The smart fabric uses lyocell fabric as a substrate, and a fabric composite material is formed by alternately loading modified MXene nanosheets and imidazole-based MOF flame retardants onto the fabric surface using surface deposition technology. The preparation method includes: synthesizing a two-dimensional transition metal carbide (modified MXene) dispersion and a molybdenum-based metal-organic framework (imidazole-based MOF flame retardant) solution; pretreating the fabric; loading the modified MXene solution and imidazole-based MOF flame retardant onto the pretreated fabric using surface deposition technology, followed by drying. The smart fabric prepared by this invention integrates flame retardancy, fire early warning, and thermal management functions, exhibiting excellent electrothermal and photothermal conversion performance. It can achieve rapid early warning (≤3s) upon contact with fire through a sudden change in resistance, and the coating composed of modified MXene and imidazole-based MOF flame retardant effectively inhibits heat release and smoke release, significantly improving the fabric's fire safety.
