Published in 2021 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202011008

Abstract: The desirable self‐assembly (SA) of repeated 2D stacked layers requires a “holistic analysis” of three interconnected components: the electrode, the interface, and the molecular component; among them, the contact interface bears the largest burden responsibilities.… read more here.

Published in 2025 at "Advanced Functional Materials"

DOI: 10.1002/adfm.202518597

Abstract: Conventional dry‐processed electrode (DPE) fabrication using polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF) offers a solvent‐free alternative to wet‐coating processes that rely on toxic N‐methyl‐2‐pyrrolidone. However, traditional DPE systems often struggle with a trade‐off between internal… read more here.

Published in 2023 at "Advanced Materials"

DOI: 10.1002/adma.202207798

Abstract: Conventional processes for depositing thin films of conjugated polymers are restricted to those based on vapor, liquid, and solution‐phase precursors. Each of these methods bear some limitations. For example, low‐bandgap polymers with alternating donor–acceptor structures… read more here.

Published in 2025 at "Advanced Materials"

DOI: 10.1002/adma.202508162

Abstract: Conventional hydrogel preparation typically involves the use of solvents (mostly water), which increases the free volume between polymer chains and weakens their interactions, resulting in mechanically weak hydrogels with limited viscoelasticity. Here, a solvent‐free synthesis… read more here.
