摘要/Abstract

摘要：

纸张基材具备的多孔特性使其表面的液体材料产生了渗透、扩散等现象,因此在纸基的表面利用化学镀形成RFID标签金属天线极为困难。针对这个问题,文中采用氯化亚锡胶体溶液对纸张表面进行处理以避免转印油墨渗透。为进一步提高RFID标签天线金属层的导电性和附着力,采用壳聚糖溶液处理纸张基板表面以引入对催化离子具有吸附性的功能基团。SEM、XRD、EDS和附着力测试证明,文中所制备RFID标签天线的金属层表面具有致密、结晶度高、附着力良好、电阻率低(2.58×10 ^-8 Ω·cm)且机械性能良好(1 000次弯曲)等优点。

Abstract:

The porous characteristic of the paper substrate causes penetration and diffusion of the liquid material on the surface. Therefore, it is extremely difficult to form an RFID tag metal antenna by electroless deposition on the surface of the paper substrate. Aiming at this problem, the stannous chloride colloid solution was applied to avoid the catalytic ink penetration in the paper-based substrate. Moreover, paper substrate was immersed in chitosan solution, which could bring functional group and improve the conductivity and adhesion of RFID metal antenna. The SEM, XRD, EDS and adhesion test of the metal layer antenna of the RFID tag proved that the surface of the metal layer of the tag antenna had advantages including dense surface, high crystallinity, good adhesion, low resistivity (2.58×10 ^-8 Ω·cm), good mechanical properties (1 000 bending test).

Key words: paper substrate, surface modification, metal layer, chitosan, RFID label, flexibility
