Wicking-Polarization-Induced Water Cluster Size Effect on Triboelectric Evaporation Textiles

Sweating during exercise, physical labor, or hot weather leads to a feeling of discomfort. The stuffiness, stickiness, and heaviness brought by sweat may promote negative emotions or disease. Clothing, textiles, and wearable devices exacerbate these problems by restricting evaporation of sweat. Here, a textile that can promote and enhance sweat evaporation by coupling wicking and polarization is reported. The wicking is produced by the wettability gradient and pore size, which make the surface moisture content of the textile in contact with the skin strictly 0%. The polarization is driven by a ferroelectric-enhanced triboelectric textile. This textile degrades large-sized water clusters into small-sized water clusters or water monomers, so that the textiles have an excellent moisture evaporation rate (4.4 and 3.6 times faster than the cotton and polyester textiles, respectively). This work provides a new source of inspiration for quick-drying textiles and also finds an attractive application for triboelectric technology.

Automated summary

The study introduces a textile that promotes and enhances sweat evaporation through wicking and polarization, degrading large water clusters into smaller ones and possessing an excellent moisture evaporation rate.
