Water-Repellent Textile via Decorating Fibers with Amphiphilic Janus Particles

Abstract

We investigated morphology and wetting properties of textiles modified by chemically immobilized amphiphilic micrometer and submicrometer large Janus particles. The Janus particles bind by their reactive side to the textile surface, while their hydrophobic side faces the environment. It was found that the character of immobilization of the Janus particles on textile depends on their size: larger particles bind between fibers, while smaller ones bind to the fiber surface. In both cases, immobilization of Janus particles results in the hydrophobization of the hydrophilic textile surface. Finally, we demonstrated that submicrometer large Janus particles are very efficient for the design of water-repellent textiles.

Co-flow microfluidic synthesis of liquid crystalline actuating Janus particles

“…Amphiphilic Janus particles have been studied intensely for their application as solid surfactants and interface stabilizers, catalysts and super-hydrophobic textiles and coatings. [13][14][15][16][17] Electrical and magneto-responsive Janus particles, featuring asymmetric optical properties, offer their usage for switchable display devices and electronic paper. [18][19][20] An increasing interest has grown in stimuli responsive Janus particles, which are sensitive to changes in their physical or chemical environment, such as the temperature, light or pH-value.…”

Fabrication of superhydrophobic and superoleophilic textiles for oil–water separation

“…There have been many reports about endowing common textiles with superhydrophobicity, focusing mainly on lotus effect for water-repelling or self-cleaning [15][16][17][18][19][20][21][22][23][24]. However, only a few literatures report on fabrication of superhydrophobic textiles for water-oil separation [25,26].…”

Targeted partial finishing of barrier textiles with microparticles, and their effects on barrier properties and comfort

“…by spraying, rolling, impregnating, dipping, or printing. As shown in Behera and Arora [7] and Synytska et al [8], ultra-hydrophobic surfaces can enhance the barrier effect of the textiles by increasing the intrusion pressure. In the abovementioned finishings of woven fabrics with particles, they are evenly applied to the entire surface of the base material in suspension or aerosol form at a defined pressure gradient, in order to ensure the optimum bonding between particles and base material.…”
