摘要
在设备零部件的精准组装、产品制造过程的质量监控以及性能评估等关键环节中,界面压力的检测对于优化产品生产流程、加强质量管控和提升产品性能至关重要.虽然基于电学信号的压力传感器件在响应速率、灵敏度和压力响应范围等方面具有显著的优势,但其在界面压力成像上仍面临高成本、严苛的测试条件及多设备协同的复杂性等限制.近年来,压致变色材料因其压力成像分辨率高、成本低和易大面积制备等特点,在界面压力检测领域引起了广泛关注.当前,压致变色材料已经实现了压力分布的精确可视化,成像分辨率达到了纳米级别.然而,这些材料在压力传感精度、灵敏度和响应范围等方面的调控上仍面临一系列挑战.基于此,本文对近年来发展的压致变色材料进行综述,从压致变色机制、构效关系和性能表现等多个角度进行分类概述,并探讨了压致变色材料在实际应用中可能遇到的挑战,并提出可能的解决方案.我们期望本综述能为压致变色材料的设计、优化和应用提供有价值的参考,推动其在高端制造业和其他领域的实际应用.
Abstract
In the critical stages of precise assembly of device components,quality monitoring during product manufacturing,and performance evaluation,the detection of interface pressure is essential for optimizing production processes,strengthening quality control,and enhancing product stability.Although pressure sensors based on electrical signals exhibit significant advantages in terms of response rate,sensitivity,and pressure response range,they face limitations in interface pressure imaging,including high costs,stringent testing conditions,and the complexity of coordinating multiple devices.In recent years,piezochromic materials have garnered extensive research interest in the field of interface pressure detection due to their high-pressure imaging resolution,low cost,and ease of large-scale preparation.Currently,piezochromic materials have achieved precise visualization of pressure distribution,with imaging resolution reaching the nanometer scale.However,challenges remain in regulating pressure sensing accuracy,sensitivity,and response range.Based on this context,this paper reviews the development of piezochromic materials in recent years,focusing on their piezochromic principles,structure-property relationships,and performance characteristics.Additionally,the paper explores future development prospects and potential trends in piezochromic materials.
