摘要

摘要:我们报道了一种用于图案彩色编码的双层二向色染料掺杂液晶(BDLC)薄膜,它可以用于防伪应用,如防伪码,与传统的单层LC彩色薄膜不同,它可以根据入射光的偏振方向显示出独特的颜色变化。这是一种提高安全码安全级别的简便方法。将两层具有交叉光轴的单层LC聚合物网络膜层合制成BDLC薄膜。我们相信,BDLC薄膜可以作为一个新的平台,用于安全增强的防伪代码,可以取代复杂的手性材料或昂贵的等离子体粒子。

Security use of bilayer dichroic films made of liquid crystal polymer networks
ABSTRACT We report on bilayer dichroic dye-doped liquid crystal (BDLC) films for patternable color codes, which can be used in anti-counterfeiting applications such as security codes and, unlike the conventional single-layer LC color films, show unique color changes depending on the direction of the polarization of the incident light that passes through them. This is a facile way to enhance the security level of security codes. BDLC films are fabricated by laminating two single-layer LC polymer network films with crossed optical axes. We believe that BDLC films can be used as a new platform for a security-enhanced anti-counterfeiting code that can replace complex chiral materials or expensive plasmonic particles.
