Linen fibres were coated with a glow‐in‐the‐dark photoluminescence, flame‐retarding, and hydrophobic smart nanocomposite using the pad‐dry‐curing process. Ecologically friendly ammonium polyphosphate and lanthanide‐activated strontium aluminium oxide (LSAO) nanoparticles were immobilized into linen fabric using eco‐friendly room‐temperature‐vulcanizing silicone rubber. Different analytical techniques were used to examine the morphological characteristics and elemental compositions of LSAO nanoparticles and treated linen textiles. The self‐extinguishing properties of the treated linen textiles were tested for their fire resistance. After 24 washing cycles, the coated linen samples retained their flame‐retarding properties. The treated linen's superhydrophobicity rose in direct proportion to the LSAO concentration. After being excited at 365 nm, the colourless luminescent film that was coated on linen surface gave out an emission wavelength of 519 nm. The photoluminescent linen was monitored to create a range of different colours, including off‐white in daytime light and green under ultraviolet (UV) light radiation, according to the Commission Internationale de l'éclairage laboratory colorimetric coordinates and photoluminescence spectra. Emission, excitation, and lifetime spectral analysis of the treated linen revealed persistent phosphorescence. For mechanical and comfort evaluation, the coated linen textiles' bending length and air permeability were assessed. Good UV light shielding and enhanced antibacterial activity were detected in the treated linens.

Linen fibers were coated with a luminous, flame-retardant, and hydrophobic smart nanocomposite utilizing the pad-dry-curing process. Ecologically-friendly ammonium polyphosphate and lanthanide-activated strontium aluminum oxide (LSAO) nanoparticles were immobilized into linen fabric using the eco-friendly RTV silicone rubber. Scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), X-ray fluorescence (XRF) spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) were employed to examine the morphological characteristics and elemental compositions of LSAO nanoparticles and treated linen textiles. The self-extinguishing properties of the treated linen textiles were tested for their fire-resistance. After 24 washing cycles, the coated linen samples retained their flame-retardant properties. The treated linen's superhydrophobicity rose in direct proportion to the LSAO concentration. After being excited at 365 nm, the colorless luminescent film that was coated on linen surface gave out an emission wavelength of 519 nm. The photoluminescent linen was monitored to create a range of different colors, including off-white in daytime light and green under UV radiation, according to the CIE Lab colorimetric coordinates and photoluminescence spectra. Emission, excitation and lifetime spectral analysis of the treated linen revealed persistent phosphorescence. For mechanical and comfort evaluation, the coated linen textiles' bending length and air permeability were assessed. Excellent UV protection and enhanced antibacterial properties were found in the treated linens. Large-scale manufacturing of multipurpose technical fabrics, such as tents, might benefit from the current simple technique.

Photochromism has been used as an attractive method to enhance the authentication of commercially available goods. It has been fundamental to enhance the engineering procedure of the authentication materials to introduce a mechanically reliable authentication nanofibrous film. In this context, we develop a mechanically reliable and photoluminescent electrospun nanofibrous polycarbonate film immobilized with lanthanide‐doped aluminate nanoparticles (NPs) by the electrospinning method for authentication purposes. The prepared composite film displayed photochromism by changing color from transparent under daytime light to green under ultraviolet light. To guarantee the transparency of the electrospun nanofibrous film, the strontium aluminate pigment must be presented in the nano‐scaled particle form to improve its distribution without forming aggregates in the electrospun polycarbonate nanofibrous bulk. The pigment‐polycarbonate nanofibers showed an emission band at 512 nm upon excitation at 374 nm. The pigment‐polycarbonate nanofibers showed an improved hydrophobicity with raising the pigment ratio without adverse influences on their inherent appearance and mechanical characteristics. When excited with UV light, the transparent films had rapid and reversible photochromism without fatigue. The nanofibrous mats displayed elasticity and flexibility. The present approach can be described as a competent method for the preparation of diverse anticounterfeiting materials.
