In this paper, based on high-throughput technology, polymer dispersed liquid crystals (PDLC) composed of pentaerythritol tetra (2-mercaptoacetic acid) (PETMP), trimethylolpropane triacrylate (TMPTA), and polyethylene glycol diacrylate (PEGD 600) were investigated in detail. A total of 125 PDLC samples with different ratios were quickly prepared using ink-jet printing. Based on the method of machine vision to identify the grayscale level of samples, as far as we know, it is the first time to realize high-throughput detection of the electro-optical performance of PDLC samples, which can quickly screen out the lowest saturation voltage of batch samples. Additionally, we compared the electro-optical test results of manual and high-throughput preparation PDLC samples and discovered that they had very similar electro-optical characteristics and morphologies. This demonstrated the viability of PDLC sample high-throughput preparation and detection, as well as promising application prospects, and significantly increased the efficiency of PDLC sample preparation and detection. The results of this study will contribute to the research and application of PDLC composites in the future.
本文基于高通量技术，详细研究了由季戊四醇四（2-巯基乙酸）（PETMP）、三羟甲基丙烷三丙烯酸酯（TMPTA）和聚乙二醇二丙烯酸酯（PEGD600）组成的聚合物分散液晶（PDLC）。使用喷墨打印快速制备了总共 125 种具有不同比例的 PDLC 样品。基于机器视觉识别样品灰度级别的方法，据我们所知，这是首次实现 PDLC 样品电光性能的高通量检测，可快速筛选出批量样品的最低饱和电压。此外，我们比较了手动和高通量制备 PDLC 样品的电光测试结果，发现它们具有非常相似的电光特性和形态。这证明了 PDLC 样品高通量制备和检测的可行性以及广阔的应用前景，显著提高了 PDLC 样品制备和检测的效率。本研究的结果将有助于 PDLC 复合材料在未来的研究和应用。
