Abstract Flexible fabrics with excellent photothermal conversion performance are highly demanded in developing smart textiles. This work reports the deposition of copper sulfide@polydopamine (CuS@PDA) nanocomposites on the surface of cotton fabrics. The morphology and structure of CuS@PDA coated cotton fabrics were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray

diffraction (XRD) and thermogravimetric analysis. The mechanism of the deposition and bonding of CuS@PDA on the surface of cotton fabrics was discussed. It was found that PDA coating resulted in a uniform dispersion of CuS@PDA on cotton fabrics with enhanced bonding fastness between the nanocomposites and fibrous matrix. Due to the unique encapsulation structure of CuS@PDA nanocomposites, the coated cotton fabrics were used as efficient photocatalysts for photodegradation of methylene blue. In addition, the CuS@PDA coated cotton fabrics exhibited excellent photothermal conversion and thermal imaging properties. The photocatalysis and photothermal conversion performance of CuS@PDA coated cotton fabrics endows the potential in smart textile applications.

Introduction Semiconductor compounds are promising candidates for photothermal conversion applications (Zhang et al. 2014; Jia et al. 2015). Among various gold semiconductor compound nanoparticles, copper chalcogenides (Cu2-xE, E = S, Se, Te) nanoparticles exhibit many advantages including fine-tuned localized surface plasmon resonance, broad absorption in the near infrared (NIR) region, good biocompatibility and low cost (Zhang et al. 2012; Huang et al. 2017; Bi et al., 2016). Copper sulfide (CuS) as a member of copper chalcogenides has drawn
