摘要
本研究利用辐射接枝技术,在棉布上接枝硅烷偶联剂,然后与长余辉纳米粒子进行反应键合,制备得到了一种具有高强度长余辉发光能力的改性棉织物。采用全反射红外光谱、热重分析、X射线衍射和扫描电镜等表征方法,研究了长余辉纳米粒子的附载情况,并结合光学性能表征证明其具有良好的光学性能。结果表明:该长余辉发光织物具有充能快、亮度高等特点,持续发光时间可长达10h以上,而且循环性能和再加工性能均可满足实际使用的需要。本工作制备工艺简单,原料易得,所得织物具有良好的发光能力和稳定性,在装饰、应急救援等领域具有潜在的应用前景。本研究也可为新型无机纳米粒子附载型功能织物的制备提供新思路。
This study employs radiation grafting technology to attach a silane coupling agent onto cotton fabric,followed by the cross-linking of long-afterglow nanoparticles.This process yields a cotton fabric material with a high-intensity long-afterglow luminescence capacity.Characterization techniques,including total reflection infrared spectroscopy,thermogravimetry,X-ray diffraction,and scanning electron microscopy,were employed to investigate the loading of long-afterglow nanoparticles.Additionally,optical performance characterization was conducted to confirm the excellent optical properties of the material.The findings demonstrate that this material exhibits rapid energy charging and high brightness and can emit light continuously for more than 10 h.In addition,the material exhibits satisfactory cyclic and reprocessing performance,meeting the practical requirements of various applications.Because of its straightforward production process,ready availability of raw materials,and remarkable stability,this material holds promising prospects for use in decoration,emergency response,and other domains.This study also offers novel insights into the development of functional fabrics.
