Abstract

In recent years, the fabrication of amorphous photonic crystals (APCs) structural colors on fabrics has become a research hotspot in the field of textile coloring. However, the preparation of APCs structural colored fabrics usually requires the use of black fabric as a substrate or the addition of black material for co-assembly, which greatly limits the practical application. In this study, SiO₂@PPy composite microspheres with different particle diameters were prepared as building units and deposited on white polyester fabric pre-treated with polyacrylate (PA) by atomization to form vivid structural colors. Polydimethylsiloxane (PDMS) was used as superhydrophobic agent to treat SiO₂@PPy structural colored fabrics by spraying method. The results showed that SiO₂@PPy composite microspheres with different particle diameters were prepared, which can be assembled into APCs structure on white polyester fabrics, showing different vivid structural colors. The water contact angle of structural colored fabric after PDMS treatment reached greater than 150°, showing excellent superhydrophobicity to endow it with anti-fouling property. With the introduction of PA adhesive, the structural colored fabrics had good washing and abrasion colorfastness. This study provides a new strategy for developing functional structural colored fabrics on white textile substrates.

期刊介绍： Optical Materials has an open access mirror journal Optical Materials: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The purpose of Optical Materials is to provide a means of communication and technology transfer between researchers who are interested in materials for potential device applications. The journal publishes original papers and review articles on the design, synthesis, characterisation and applications of optical materials. OPTICAL MATERIALS focuses on: • Optical Properties of Material Systems; • The Materials Aspects of Optical Phenomena; • The Materials Aspects of Devices and Applications. Authors can submit separate research elements describing their data to Data in Brief and methods to Methods X.
