配备了数字光致变色装置（DMD）的光化学打印机导致快速阐明N，N-二甲基丙烯酰胺（DMA）和N-异丙基丙烯酰胺（NIPAM）单体的表面引发原子转移自由基光聚合的动力学。这一努力揭示了相同高度的聚合物刷可以从每个单体生长的条件。利用这些数据，创建隐藏图像，这些图像在将基板加热到高于聚NIPAM的低临界溶解温度（LCST）时出现。通过引入第三单体，甲基丙烯酰氧基乙基硫代氨基甲酰基罗丹明B，在UV照射下出现第二正交图像。通过这些研究，展示了一种新的光化学打印机如何加速发现，创建任意图案，并解决刷聚合物和表面化学中的长期问题。有了这项技术在手，一个新的方法来加密超曲面内的数据。
A photochemical printer, equipped with a digital micromirror device (DMD), leads to the rapid elucidation of the kinetics of the surface‐initiated atom‐transfer radical photopolymerization of N,N‐dimethylacrylamide (DMA) and N‐isopropylacrylamide (NIPAM) monomers. This effort reveals conditions where polymer brushes of identical heights can be grown from each monomer. With these data, hidden images are created that appear upon heating the substrate above the lower critical solution temperature (LCST) of polyNIPAM. By introducing a third monomer, methacryloxyethyl thiocarbamoyl rhodamine B, a second, orthogonal image appears upon UV‐irradiation. With these studies, it is shown how a new photochemical printer accelerates discovery, creates arbitrary patterns, and addresses long‐standing problems in brush polymer and surface chemistry. With this technology in hand a new method is demonstrated to encrypt data within hypersurfaces.
