Electrochemically Driven Tandem In‐Plane Reduction and FeCl3‐ Intercalation of Highly Crystalline Graphene Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a green processing route for high‐performance reduced graphene oxide (rGO) transparent conductive films (TCFs) using highly crystalline Brodie's GO. In‐plane electrochemical reduction forms rGO on insulating substrates without toxic reductants or heat. Subsequent FeCl₃ intercalation enhances conductivity, overcoming the transparency–

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...
