Background With the rapid development of 5G and informatization technologies, product identification technologies are facing diversified and intelligent innovative demands. In the information explosion age, visual sensory experience becomes one of core elements focused by consumers, and product identification is required to bear basic functions of information transmission and meet higher requirements of users on interactivity, attractiveness and functionality. For example, the popularization of products such as sound control equipment, color-changing cups, night lights and the like all rely on innovative identification technology of materials to realize sensory interaction. However, the traditional identification means such as direct writing and laser coding are limited by background color interference and functional singleness, and it is difficult to consider high readability, anti-counterfeiting performance and user experience, and a novel identification material is needed to break through the technical bottleneck. Under the background, the temperature change film is used as an emerging intelligent identification material, the dynamic presentation of the color and the pattern is realized by sensing the temperature change, and the unique interactive experience and the anti-counterfeiting function are endowed for the product. For example, the color change can be triggered by human body touch, and the visual contrast is formed by combining the preset patterns, so that the interestingness and the safety of the mark are remarkably improved.

Therefore, on the basis of retaining the core advantages of the temperature-changing film, the problems of insufficient wear resistance, single function and the like of the intelligent identification material are solved through material and structure innovation, and the intelligent identification material becomes a key technical challenge for improving the comprehensive performance of the intelligent identification material.
