Host-guest-induced electronic state triggers two-electron oxygen reduction electrocatalysis

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Oct. 25, 2024

Supramolecular polymers possess great potential in catalysis owing to their distinctive molecular recognition and dynamic crosslinking features. However, investigating supramolecular electrocatalysts with high efficiency oxygen reduction reaction hydrogen peroxide (ORHP) remains an unexplored frontier. Herein, we present organic for ORHP by introducing cyclodextrin-containing noncovalent building blocks, affording these supramolecules abundant bonds. The electronic states kinetics are further well-modulated via a host-guest strategy, resulting appropriate regional electron binding force controllable chemical activity. Notably, integrating units into phenyl group-containing model covalent polymer achieves production rate of 9.14 mol g

Adhesion and Transparency Enhancement between Flexible Polyimide-PDMS Copolymerized Film and Copper Foil for LED Transparent Screen

Polymers, Journal Year: 2024, Volume and Issue: 16(11), P. 1591 - 1591

Published: June 4, 2024

With the increasing demand for innovative electronic products, LED transparent screens are gradually entering public eye. Polyimide (PI) materials combine high temperature resistance and transparency, which can be used to prepare flexible copper-clad laminate substrates. The physical chemical properties of PI differ from copper, such as their thermal expansion coefficients (CTEs), surface energy, etc. These differences affect formation stability interface between copper films, resulting in a short life screens. To enhance PI-copper interfacial adhesion, aminopropyl-terminated polydimethylsiloxane (PDMS) increase adhesive ability. Two diamine monomers with trifluoromethyl structure sulfone group were selected this research. Bisphenol type A diether dianhydride is monomer. All three above have non−coplanar structures structural units. adhesion optical improved synthesized films foil. containing PDMS 0, 1, 3, 5 wt% analyzed using UV spectroscopy. transmittance PI-1/3%, PI-1/5%, PI-2/3%, PI-2/5% all more than 80% at 450 nm.
