Research and Application Progress of Anti-counterfeiting Technology Based on Intelligent Material

Abstract

With the rapid development of market economy and information technology, some traditional anti-counterfeiting technologies are constantly cracked by lawbreakers. The improvement and transformation of anti-counterfeiting technologies become inevitable, and the emerging anti-counterfeiting technologies continue to move towards greenization, intelligence and popularization. Based on the research status domestic and overseas, the paper not only defined the basic concepts of smart materials, but divided them into four parts including novel nano-materials, stimulus response materials, shape memory materials and other new-type materials. The anti-counterfeiting mechanism and application cases of new nano-ink, nano-structure material and nano-composite were introduced emphatically. The research progress and potential application in anti-counterfeiting areas of stimulus-responsive materials were overviewed briefly from the perspective of inducement factors of light, electricity and magnetism etc. In addition, the basic principle of the anti-counterfeiting labels combined with the shape memory materials was analyzed. Finally, the paper also involved the anti-counterfeiting applications of other intelligent anti-counterfeit materials, such as new card-based material (PHA), functional anti-counterfeiting paper and molding resin, which expanded the application fields of intelligent materials. It concluded that intelligent materials have a broad application in the field of anti-counterfeiting. The paper can provide a powerful theoretical guide for the further application of intelligent materials in anti-counterfeiting.
