The integration of nanotechnology and textile engineering has promoted the development and performance improvement of multifunctional intelligent materials in various application fields.
On June 13, 2024, the Chemical Engineering Journal reported that researchers used a one-step method to anchor silver nanoparticles (AgNPs) onto multi walled carbon nanotubes (CNTs) and spray them onto non-woven fabrics to synthesize a multifunctional smart textile.
The addition of carbon nanotubes not only enhances the conductivity of the fabric, but also improves the heating efficiency of the fabric, thereby improving its comfort in cold environments through electric heating. The addition of AgNPs enhances the photothermal function of the fabric. Under illumination of 100mW/cm, the photothermal conversion efficiency reaches 89.7%, and at a current of 1.0A, the temperature can reach 45.0 ° C.
The study also found that the fabric has excellent piezoresistive and strain sensing capabilities, with a response time of only 359ms at a pressure of 3.25kPa. In addition, the fabric can also detect subtle physiological signals such as the wearer's pulse, finger bending, and spinal curvature, while also monitoring environmental humidity in real-time.
This study not only promotes the development of intelligent textile technology, but also solves the unique challenges faced in the one-step preparation of CNTs and AgNPs on non-woven fabrics, thereby achieving the design and manufacturing of innovative materials with customized functions.

These developments will have significant impacts on fields such as electric heating, photothermal effects, heat conduction, and heat treatment.
