Non-Angle-Dependent Structural Colored Fabric with Dynamic Thermal Management

Abstract

Textile dyeing that is based on structural colors has attracted great attention due to its environmental friendliness and long-lasting color fastness. However, most structural colored fabric studies only focus on improving the color and stability of the fabric, neglecting the increasing demand for multifunctional textiles in daily life. Herein, a simple and effective method was used for preparing multifunctional structural colored textiles. PMMA microspheres that were prepared by a simple emulsion polymerization method and coated with black PDA were used to prepare structural color nanospheres with higher color rendering. MXene with high conductivity was prepared using the in-situ HF etching method to modify cotton fabric. The conductive structural colored fabric was obtained by self-assembling PMMA@PDA microspheres onto the modified cotton fabric through a simple blade coating method. The prepared conductive structural colored textile retains its softness and demonstrates good electrothermal performance and durable color fastness through washing, friction, and durability tests. This work provides a novel approach for creating bifunctional structural colored textiles that are suitable for electrothermal applications.
