The paper I would like to nominate that stimulated my color chemistry passion and had constructive impact on me in teaching dye chemistry classes and in my research on functional dyes is entitled: ‘Smart textiles: an overview of recent progress on chromic textiles’ by Ramlow, Andrade and Immich. The paper provides a comprehensive and a state-of-theart review of different types of chromic textiles including photochromic, thermochromic, electrochromic, halochromic, solvatochromic and ionochromic along with the reaction mechanisms showing color change as a result of an external stimulus. It also provides a good coverage of performance characterization, challenges and future directions of chromic textiles, and it is one of the highly cited papers in the JTI with 31 citations so far. Photochromic textiles undergo reversible color change when they are subjected to electromagnetic radiation. The most common photochromic dyes are based on spiropyrans, spirooxazines, naphthopyrans, azobenzene, fulgids and diaryltenenes. The most desired photochromic textiles are those that demonstrate excellent color resistance properties with excellent washfastness and lightfastness after exposure to UV irradiation, which can be used in the manufacture of innovative and smart materials for smart UV-blocker garments, sensing environmental changes, military camouflage, brand protection, security printing, sports clothing and clothing for special services such as fire brigades and police, fabric-based electronic image displays, security barcodes, sensor systems, solar heat and light management. Due to constant exposure to UV, photochromic compounds undergo photodegradation. Microencapsulation of photochromic dyes is one of the approaches for reducing the photodegradation of photochromic compounds as a result of repetitive cycles of UV irradiation. Thermochromic textiles undergo reversible color change due to changes in their molecular structures as a result of changes in the environmental temperature. A thermochromic system is a mixture of a leuco dye, a developer and a solvent in specific ratios. Reversible thermochromic microencapsulated phase change materials with good stability were developed in 2018 by Geng et al. in thermal protective textiles for thermal energy storage application. Electrochromic textiles undergo color changes upon applying an electrical potential. The optical properties of electrochromic textiles are governed by its oxidation state, which can be controlled by the oxidation-reduction process. For example, wool with electrochromic properties was developed by Koc et al (2017) using indium tin oxide (ITO) and tungsten oxide. There are other types of chromic textiles including halochromic, changing color as a function of pH, solvatochromic, changing absorption or emission spectrum as a function of solvent polarity, and ionochromism, which changes color due to a change in the absorption or emission spectra of the molecule as it interacts with ionic species.
