投影式光固化打印压电材料的近期研究进展
压电材料是受压力作用时会在相对表面两端界面之间产生电压的晶体材料,可适用于换能器,传感器、驱动器、声纳、手机和机器人等应用。相较于其他3D打印制备技术,投影式光固化3D打印技术,尤其是PµSL,在打印速度和分辨率方面都有明显的优势((26,000 mm2h-1, 10 μm),挤出式(0.2–113 mm2 h-1, 10–120 μm),气溶胶喷射(19–5,600mm2 h-1,100 μm),多工艺协作制备( multiprocesstechniques)(11 mm2 h-1,100 μm)。本文整理了近年间期刊上压电材料的相关研究进展,供大家参考,如对这个方向感兴趣,欢迎和我们联系,一起探讨光固化打印压电材料的技术和应用。Nature Electronics:PµSL制备价态可控的多材料压电器件一句话总结:采用PµSL的技术打印3D结构,然后选择性沉积一种或多种材料(金属、陶瓷、半导体材料等)在已打印的3D结构的任意指定位置,实现了价态可控的3D压电器件的制备。论文信息:Hensleigh R., Cui H.
