研究了以聚乙烯醇缩丁醛（PVB）为粘结剂对钛酸钡绿色陶瓷片进行表面改性，成功地在绿色陶瓷片上制备了具有氨基和硅醇基团的图案化自组装单分子膜（SAM）。然后将图案化的SAM浸入含有在水中显示负ζ电位的Ni颗粒的水中。Ni颗粒被吸引到图案化的SAM的氨基基团，其通过吸引性静电相互作用显示正zeta电位。因此，在室温下在水中使用SAM实现Ni颗粒的微图案。该工艺可用于制备小型化高性能多层陶瓷电容器（MLCC）的薄且均匀的内镍电极。
We studied surface modification of ceramic BaTiO3green sheets including polyvinylbutyral (PVB) as an organic binder and successfully fabricated a patterned self-assembled monolayer (SAM) which has a region of amino groups and a region of silanol groups on the green sheet. The patterned SAM was then immersed in water containing Ni particles that show negative zeta potential in water. Ni particles were attracted to the amino groups of the patterned SAM that show positive zeta potential by attractive electrostatic interaction. Consequently, a micropattern of Ni particles was achieved using a SAM at room temperature in water. This process can be used to fabricate a thin uniform internal Ni electrode for miniaturized high-performance multilayer ceramic capacitors (MLCC).
