胶体微球墨水的pH值与自组装结构生色的相关性研究

研究胶体微球墨水的pH值对自组装结构生色和墨水稳定性能的影响。采用三维视频显微镜、DigiEye数慧眼系统、场发射扫描电镜（FE-SEM）和纳米粒度及分子量分析仪分别对胶体微球自组装产生的结构色、光子晶体结构的规整性以及胶体微球墨水的存放稳定性进行表征,并就相关影响因素进行分析。结果表明,胶体微球墨水的pH对自组装结构生色及墨水的存放稳定性均有显著影响,在pH为7~8时,胶体微球墨水具有较好的稳定性,且自组装光子晶体结构色的色彩艳丽。

Correlation Study on pH Value of Colloidal Microsphere Ink and Self-assembly Structural Color

This paper studies the influence of pH value of colloidal microsphere ink on self-assembly structural color and stability performance of the ink,characterizes the structural color produced by self-assembly of colloidal microsphere,regularity of photonic crystal structure and storage stability of colloidal microsphere ink respectively with three-dimensional video microscope,DigiEye system,field emission scanning electron microscopy（FE-SEM）and nano particle and molecular weight analyzer and analyzes relevant influencing factors.The result shows that pH of colloidal microsphere ink has significant influence on self-assembly structural color and storage stability of the ink;colloidal microsphere ink has a good stability when pH=7~8and self-assembly photonic crystal structural color is bright.
