Abstract:

In order to reasonably explore the method of intelligence to the luminescent polyurethane, the flexible luminescent polyurethane composite (LPC) with thermochromic function was prepared by coating finishing. The surface roughness of the material was observed by scanning electron microscope (SEM). X-ray diffractometer (XRD) analysis showed that the coating process and the addition of pigments did not affect the phase structure of the rare earth luminescent materials. The reflectance and emission spectra indicated that the material has excellent thermochromic luminescence characteristics. Under standard light source, the color of material itself can be changed by body temperature (from red to white). After excited by ultraviolet-visible light source, the system of low-temperature red light and high-temperature white light was formed in dark environment, which fully demonstrated its application potential in the field of smart wearable devices.

Key words: coating finishing, thermochromic, luminescent polyurethane, composite, smart wearable

摘要:

为合理探讨使发光聚氨酯智能化的方法,本研究采用涂层整理的方式制备出具有热敏变色功能的柔性发光聚氨酯复合材料(LPC)。扫描电子显微镜(SEM)观察到材料表面粗糙不平;X射线衍射仪(XRD)分析表明涂层工艺和颜料的添加未影响材料中稀土发光材料的物相结构;反射率和发射光谱测试显示材料具有优异的热敏变色发光特性,标准光源下材料自身颜色可通过人体体温来改变(由红色变为白色),经紫外-可见光源激发后,在黑暗环境中形成低温红光-高温白光的体系,充分展示其在智能可穿戴设备领域的应用潜力。
