| description | The field of 3D printing is growing rapidly and offers a wide range of potential applications, particularly with the use of Shape Memory Polymers (SMPs). However, current studies on SMP-based 3D printing have mainly focused on structural design and deformation behavior. To enhance the practicality of 3D printed structures, the ability to change color is highly desirable, especially for applications such as anti-counterfeiting, encryption, and bioinspired camouflage. This paper presents the fabrication of a UV-curable PUA-based Shape Memory Polymer (SMP) system with thermochromic and photochromic capabilities. The system is acrylate-based, making it highly UV-curable and compatible with high-resolution 3D printing techniques. Thermo/photochromic effects are achieved by adding thermochromic microcapsules to the system, resulting in printed structures that can change color upon heating or UV) exposure. The printed parts with multi-color hidden information, such as QR codes and digital numbers, were successfully demonstrated through the printing of various anti-counterfeiting patterns.And the expriment results show the exceptional multi-functional performance including shape recovery and thermo/photochromic. The development of this UV-curable PUA-based SMP system represents a significant advancement in the application of SMP-based 3D printing for anti-counterfeiting and secure data recording. |
