This study presents gravure printing as a new strategy for rapid printing of ceramic mesoporous films and highlights its advantages over conventional mesoporous film preparation using evaporation induced self-assembly together with dip-coating. By varying the printing process parameters, the mesoporous coating thicknesses can be adjusted between 20 and 200 nm while maintaining a very high film homogeneity allowing the printing of ultrathin mesoporous films. Step gradients in film composition are accessible by consecutively printing two different "inks". Thereby, gravure printing is a much faster process than mesoporous single- and multilayer preparation using conventional dip-coating because lower amounts of solution are transferred and dissolution of previously deposited layers is avoided. The effect of printing process parameters on resulting film characteristics as well as the resulting mesoporous film's ionic accessibility is systematically investigated.
本研究提出凹版印刷作为一种快速印刷陶瓷介孔薄膜的新策略，并突出其相较于使用蒸发诱导自组装和浸涂法制备传统介孔薄膜的优势。通过改变印刷工艺参数，介孔涂层厚度可在20至200纳米之间调节，同时保持非常高的薄膜均匀性，从而能够印刷超薄介孔薄膜。通过连续印刷两种不同的“油墨”，可以实现薄膜成分的阶梯梯度。因此，凹版印刷比使用传统浸涂法制备介孔单层和多层薄膜的过程要快得多，因为转移的溶液量较少，且避免了先前沉积层的溶解。系统地研究了印刷工艺参数对所得薄膜特性以及所得介孔薄膜离子可及性的影响。
