However, the homogeneous micro-structure without the aid of templates or composite presents a significant obstacle, due to the intrinsic softness of the dominant PSS component. In this study, we have successfully developed a porous configuration by employing a solvothermal approach with ethylene glycol (EG) as the solvent. The synergistic action of elevated pressure and temperature was crucial in prompting EG to tailor the microstructure of the PEDOT:PSS films by removing non-conductive PSS chains and improving PEDOT crystallinity, and the formation of a porous network. The resulting porous PEDOT:PSS films exhibited a high conductivity of 1644 ​S ​cm⁻¹ and achieved a volumetric capacitance record of 270 ​F ​cm⁻³, markedly exceeding previous records. The flexible all-solid-state supercapacitor assembled by the films had an outstanding volumetric capacitance of 97.8 ​F ​cm⁻³ and an energy density of 8.7 ​mWh cm⁻³, which is best one for pure PEDOT:PSS-based supercapacitors. Grazing-incidence wide-angle X-ray scattering, X-ray photo-electron spectroscopy, and other characterizations were carried out to characterize the structure evolution.

Herein, we developed an interface self-assembly (ISA) method to create a uniformly distributed gold nanolayer at a liquid-liquid interface for positive heavy metal ions capture and NELIBS analysis. The electrostatically self-assembled Au nanoparticles (NPs)-analytes membrane was prepared at the oil-water interface by injecting ethanol into the mixture of cyclohexane and Au NPs-analytes water solution.

This would be a step forward in creating standalone silicon photonic devices, strengthening the possibility of single on-chip nanophotonic integrated circuits.

Early evaluating coating microdefects and detecting corrosion sites are urgent yet remain challenge to achieve. Herein, we propose a robust, universal and efficient fluorescence-based strategy for hierarchical warning of coating damage and metal corrosion by introducing the concepts of damage-induced fluorescence enhancement effect (DIE) and ionic-recognition induced quenching effect (RIQ). The coatings with dual-responsiveness for coating defect and steel corrosion are constructed by incorporating synthesized nanoprobes composed of metal organic frameworks (Ni–Zn-MOFs) loaded with Rhodamine B (RhB@MOFs). The initial damage to the coating causes an immediate intensification of fluorescence, while the specific ionic-recognition characteristic of RhB with Fe³⁺ results in an evident fluorescence quenching, enabling the detection of coating damage and corrosion. Importantly, this nanoprobes are insensitive to the coating matrix and exhibit stable corrosion warning capability across various coating systems. Meanwhile, electrochemical investigations indicate that the impedance values of RM/EP maintain above 10⁸ ​Ω ​cm² even after 60 days of immersion. Therefore, the incorporation of fluorescent nanoprobes greatly inhibits the intrusion of electrolytes into polymer and improves the corrosion protection performance of the coating.
