A Novel Polymeric Substrate with Dual‐Porous Structures for High‐Performance Inkjet‐Printed Flexible Electronic Devices

Inkjet printing has emerged as a promising low-cost and high-performance method for manufacturing printing-based devices. However, the development of optimized substrates inkjet using novel materials is limited. In this study, polymeric substrate flexible electronic devices fabricated thin-film processing phase inversion polyethersulfone (PES). The PES film consists two layers pores; upper layer nano-sized pores that filter nanoparticles in conductive ink allow high-density aggregation on substrate, while lower contains micro-scale quickly absorb drain solvent. porous structures lead to higher conductivity high-resolution printed patterns by minimizing solvent lateral diffusion. Additionally, can undergo high-temperature curing metal nanoparticles, enabling pattern with low resistance. highly transparent flexible, allowing fabrication various production
