摘　　要：如果某种材料在指压作用下即可发光,结合图文设计和印刷,可开发出多种新颖防伪产品,具有巨大的市场需求。现有力致发光材料发光亮度低以及发光压力阈值过大而无法实现指压发光。在总结力致发光材料在防伪方面应用现状的基础上,分析了现有ML的发光压力阈值和发光颜色的调控方法,提出:新的化学组成体系、构建可高效传递作用力的聚合物基质、设计制备表面微纳结构阵列增强力敏特性是实现指压发光现象的有效途径。If the material can emit light under finger pressure,and with the combination of graphic design and printing,various novel anti-counterfeiting products would be developed,which has a huge market demand.It is not possible to achieve finger pressure luminescence because of the low luminous intensity and the large luminescent pressure threshold of mechanoluminescence materials.On the basis of summing up the application status of mechanoluminescence(ML)materials in anti-counterfeiting,the methods of controlling luminescent pressure threshold and luminescent color of ML is analyzed.Effective ways to achieve finger pressure luminescence in anti-counterfeiting applications are proposed,such as new chemical composition systems,the construction of a polymer matrix that can efficiently transfer forces,and the design and preparation of surface micro-nano structure arrays to enhance force sensitivity.
