激光诱导向前转移薄膜材料的研究进展

激光诱导向前转移技术(LIFT)是一种新兴数字打印技术，利用脉冲激光束透过石英基板辐射供体材料，进而推动部分材料于受体表面沉积成膜。LIFT技术具有打印膜层精度高、非接触式沉积、操作环境限制低和可操作性高等特点。LIFT技术印刷材料跨度大意味着更广泛的激光诱导向前转移技术应用领域，从表面微结构到印刷电极，从化学传感器到航空航天设备。随着各种功能化材料的需求出现，LIFT技术不断创新，目前包括吸收层LIFT技术、气泡驱动LIFT技术、动态释放层LIFT技术和基质辅助脉冲激光蒸发直写技术等。针对固相与液相的薄膜材料，从激光与材料相互作用及转移的机制方面进行了归纳，综述了LIFT技术在制造各种功能器件的研究进展，希望为该技术进一步发展提供新思路，以应对在多尺度多材料应用平台开发相关材料的挑战。

Research Progress of Laser-induced Forward Transfer Thin Films

Laser-induced forward transfer (LIFT) is an emerging digital printing technology that used a pulsed laser beam to radiate donor material through a quartz substrate, driving part of the material to deposit films on the recipient surface. LIFT has high printing film accuracy, non-contact deposition, low operating environment constraints, and high operability. The large span of LIFT printing materials means a wider range of laser-induced forward transfer applications, from surface microstructures to printed electrodes, from chemical sensors to aerospace equipment. With the emergence of a variety of functional materials, LIFT technology innovation, including absorption layer LIFT technology, bubble driven LIFT technology, dynamic release layer LIFT technology and matrix-assisted pulsed laser evaporation direct writing technology. In this paper, it summarized the interaction and transfer mechanism between laser and material for solid and liquid phase thin film materials. Finally, the application direction of digital printing of thin film was prospected. In conclusion, we hoped that the introduction and summary of this paper can provide new ideas for the further development of this technology, so as to meet the challenge of developing related materials in multi-scale and multi-material application platforms.
