Article Synopsis
- Researchers have developed MnO-Ag nanojunctions that enhance the performance of photoreversible color switching systems (PCSSs), which could replace traditional photochromic materials by utilizing unique photocatalytic and photothermal properties.
- These nanojunctions are created using specific chemical precursors and feature nanoparticles of MnO decorated with silver nanodots, improving their ability to absorb visible light and promoting efficient color switching through a two-step light irradiation process.
- The combination of these nanojunctions with redox dyes allows for the creation of rewritable inks capable of changing color under different light wavelengths, enabling the development of rewritable fabrics with impressive durability and reversibility.
The conventional dyeing process requires a substantial amount of auxiliaries and water, which leaches hazardous colored effluents to the environment. Herein, a newly developed sustainable spray dyeing system has been proposed for cotton fabric in the presence of reactive dyes, which has the potential to minimize the textile dyeing industries environmental impact in terms of water consumption and save significant energy. The results suggest that fresh dye solution can be mixed with an alkali solution before spray dyeing to avoid the reactive dye hydrolysis phenomenon.
