Colorful cholesteric liquid crystal polymer network (CLCN) patterns can be applied for decoration and anti-counterfeiting. Herein, the CLC inks were prepared using an acrylate liquid crystal, chiral dopants and a photoinitiator. Full-color CLCN patterns were able to be printed out using only two CLC inks by changing their volume ratio. A structure with a gradient helical pitch was identified between different colors. For anti-counterfeiting, the color patterns composed of opposite-handed CLCNs were also printed. A helical-nonhelical-helical structure was identified at the interface. In addition, CLCN patterns with a grating structure were also prepared. The results shown here not only give us a better understanding the cholesteric structure, but also lay the foundations for the applications of CLCN patterns in the fields of decoration and anti-counterfeiting.

使用胆甾型液晶油墨制备的彩色胆甾型液晶聚合物网络图案

彩色胆甾型液晶聚合物网络（CLCN）图案可用于装饰和防伪。在此，使用丙烯酸酯液晶、手性掺杂剂和光引发剂制备CLC墨水。通过改变它们的体积比，仅使用两种 CLC 墨水就可以打印出全色 CLCN 图案。在不同颜色之间识别出具有梯度螺距的结构。为了防伪，还印刷了由相反方向的CLCN组成的彩色图案。在界面处发现了螺旋-非螺旋-螺旋结构。此外，还制备了具有光栅结构的CLCN图案。这里显示的结果不仅让我们更好地了解胆甾结构，而且为CLCN图案在装饰和防伪领域的应用奠定了基础。
