We report a controlled deposition process using atmospheric plasma to fabricate silver nanoparticle (AgNP) structures on polydimethylsiloxane (PDMS) substrates, essential for stretchable electronic circuits in wearable devices. This technique ensures precise printing of conductive structures using nanoparticles as precursors, while the relationship between crystallinity and plasma treatment is established through X-ray diffraction (XRD) analysis. The XRD studies provide insights into the effects of plasma parameters on the structural integrity and adhesion of AgNP patterns, enhancing our understanding of substrate stretchability and bendability. Our findings indicate that atmospheric plasma-aided printing not only avoids the need for high-temperature sintering but also significantly enhances the electrical and mechanical properties of the conductive structures, advancing the production of robust and adaptable electronic devices for wearable technology.
我们报告了一种使用大气等离子体在聚二甲基硅氧烷（PDMS）基板上制造银纳米颗粒（AgNP）结构的可控沉积工艺，这对于可穿戴设备中的可拉伸电子电路至关重要。该技术确保使用纳米颗粒作为前体精确印刷导电结构，同时通过X射线衍射（XRD）分析建立结晶度与等离子体处理之间的关系。XRD研究深入了解了等离子体参数对AgNP图案的结构完整性和附着力的影响，增强了我们对基板拉伸性和可弯曲性的理解。我们的研究结果表明，大气等离子体辅助印刷不仅避免了高温烧结的需要，而且显著提高了导电结构的电气和机械性能，推动了用于可穿戴技术的坚固且适应性强的电子设备的生产。
