Simple preparation of flame-retardant, photoluminescent, and superhydrophobic smart nanocomposite coating was developed and applied onto cotton fibres using the simple pad–dry–cure technique. This novel strategy involved the immobilization of rare-earth-doped aluminium strontium oxide (ASO; SrAl₂O₄:Eu⁺²,Dy⁺³) nanoparticles, environmentally friendly room temperature vulcanizing silicone rubber (RTV) and environmentally friendly Exolet AP422 (Ex). The fabrics were also able to produce a char film in the fire-resistant assessment, providing fibres with a self-extinguishing characteristic. Furthermore, the fire-retardant performance of the coated cotton samples remained resistant to washing over 35 laundry cycles. The superhydrophobicity of the treated fabrics was monitored to improve by increasing the photoluminescent phosphor nanoparticles. The produced transparent photoluminescent film displayed an absorption at 360 nm and an emission at 526 nm. The photoluminescent fabrics were observed to generate different colorimetric shades, including white, green-yellow and bright white as monitored by Commission Internationale de l'Éclairage laboratory colorimetric coordinates. Slow emissions were detected for the treated cotton fabrics as monitored by emission, ultraviolet–visible light absorption, lifetime, and decay time spectral profiles to indicate glow in the dark phosphorescence effect. Both comfort and mechanical properties of the coated fibres were evaluated by measuring their bending length and air permeability.

多功能长余辉光致发光纤维素纤维的制备

开发了一种简单的阻燃、光致发光和超疏水的智能纳米复合涂层，并使用简单的垫-干-固化技术应用于棉纤维。这种新颖的策略涉及稀土掺杂的铝锶氧化物 (ASO; SrAl ₂ O ₄ :Eu ⁺² ,Dy ⁺³) 纳米粒子、环保型室温硫化硅橡胶 (RTV) 和环保型 Exolet AP422 (Ex)。这些织物还能够在耐火评估中产生炭膜，为纤维提供自熄特性。此外，涂层棉样品的阻燃性能在 35 次洗涤循环后仍能保持耐洗。通过增加光致发光磷光体纳米颗粒来监测处理过的织物的超疏水性。制备的透明光致发光膜在 360 nm 处显示吸收，在 526 nm 处显示出发射。观察到光致发光织物产生不同的色度色调，包括由国际委员会监测的白色、绿黄色和亮白色 Éclairage 实验室比色坐标。通过发射、紫外-可见光吸收、寿命和衰减时间光谱曲线监测处理后的棉织物检测到缓慢发射，以指示暗磷光效应中的发光。通过测量它们的弯曲长度和透气性来评估涂层纤维的舒适性和机械性能。
