AI Technical Summary

Technical Problem

Existing aramid nano aerogel fibers are hydrophilic, prone to water absorption, and require post-treatment hydrophobic modifications that are complex and unsustainable, limiting their practical application.

Method used

In-situ hydrophobic modification of aramid nano aerogel fibers through a spinning process using a halogenated reagent and alkaline solvent, creating active sites for graft modification, resulting in a stable three-dimensional porous network structure.

Benefits of technology

The modified fibers exhibit high porosity, tensile strength, and self-cleaning ability, suitable for large-scale production and applications in textiles and other fields, with improved hydrophobic performance resisting common liquids.
