In this work, an effective method was developed to fabricate bendable circuits on a polydimethylsiloxane (PDMS) surface by inkjet printing semi-wrapped structures. It is demonstrated that the precured PDMS liquid film could influence the depositing morphology of coalesced silver precursor inkjet droplets. Accordingly, continuous and uniform lines with a semi-wrapped structure were fabricated on the PDMS surface. When the printed silver precursor was reduced to Ag nanoparticles, the fabricated conductive film exhibited good transparency and high bendability. This work presented a facile way to fabricate flexible patterns on a PDMS surface without any complicated modification or special equipment. Meanwhile, an hydrazine reduction of Ag has been reported using the vapor phase method in the fabricating process.
在这项工作中，开发了一种有效的方法，通过喷墨打印半包裹结构在聚二甲基硅氧烷（PDMS）表面制造可弯曲电路。结果表明，预固化的PDMS液膜会影响聚结的银前驱体喷墨液滴的沉积形态。因此，在PDMS表面制备了具有半包裹结构的连续且均匀的线条。当印刷的银前驱体还原为银纳米颗粒时，制备的导电膜表现出良好的透明度和高柔韧性。这项工作提出了一种在PDMS表面制造柔性图案的简便方法，无需任何复杂的修饰或特殊设备。同时，在制造过程中已经报道了使用气相法对银进行肼还原。
