Infiltrated thin film structure with hydrogel-mediated precursor ink for durable SOFCs
Abstract The hydrogel of biomolecule-assisted metal/organic complex has the superior ability to form a uniform, continuous, and densely integrated structure, which is necessary for fine thin film fabrication. As a representative of nature-originated polymers with abundant reactive side chains, we se...
