“…And Figure c shows the relationship between surface energy, WCA, hexadecane contact angle (called OCA), and fluorination time, and the corresponding data are summarized in Table S5. It can be seen that the value of the WCA gradually increases with the continuous increase of the fluorination time until the fluorination time reaches 8 h, and a superhydrophobic state with a WCA of 153.6° appears. As the fluorination time continues to increase, it can be seen that the value of the WCA does not fluctuate much, indicating that the PFDT load has reached saturation at this time.…”

As one of the most important wearable devices, flexible sensors have attracted the attention of researchers because they can be installed onto the skin of a human to monitor their movement, and they have the advantages of excellent flexibility and comfort. However, most of the devices cannot be used in an underwater environment, and they may be destroyed by mechanical forces in harsh working conditions. There are many approaches to solve these issues, but unfortunately, less research has been carried out to solve them simultaneously. To overcome these challenges, this research proposes a method for developing a sensor integrating superhydrophobicity and self-healing ability. The experimental results demonstrated that the sensor exhibited excellent performance with a water contact angle of 153.6°, a gauge factor of 145, and more than 10 000 cycle stability. In addition, it could self-heal at 50 °C after scratch, and the self-healing efficiency was 85.6%. It was capable of monitoring various movements, such as coughing, speaking, the bending and stretching of knees, elbows, and fingers. Furthermore, this device can be employed to monitor the human movement of swimming, and it can also realize underwater vibration and impact of tiny droplets. This work provides a valuable design strategy for electrical devices that can be widely applied in various fields.

“…In general, various high-performance resins can serve as carrier materials for ECAs. − Here, epoxy (type E44) was used as the resin to fabricate ECAs. Epoxy resin is a high-performance resin that plays essential roles in adhesives and matrix resins for composites and circuit boards, packaging and aircraft/aerospace components, etc. − Micron-sized silver flakes are the primary conductive filler for fabricating ECAs because of their excellent conductivity and stability.…”

Bismuth (Bi) metallic material is one of the most widely used heavy metals because of its low cost, excellent light conversion efficiency, and high X-ray attenuation coefficient. However, large-scale synthesis of highly processable and oxidation-resistant Bi nanoparticles remains challenging. Based on the above concerns, we report a facile, scalable, polyol-mediated synthesis of high-quality Bi nanoparticles using citrate as a capping agent and polyvinylpyrrolidone (PVP) as a dispersant. The presence of citrate and PVP improved Bi nanoparticle's oxidation resistance and processability. These nanoparticles can maintain excellent oxidation resistance in an ambient atmosphere for more than 120 days and form high-quality suspensions in various commonly used solvents. Moreover, large-scale and rapid synthesis of the nanoparticles was achieved by simply using the green reagent stannous citrate [tin (II) citrate] as a reducing agent. These properties make them promising as complementary conductive fillers in electrically conductive adhesives (ECAs). The Bi nanoparticles could be effectively combined with silver flakes in epoxy resins to enhance the conductivity of ECAs significantly. With the addition of only 5 wt % Bi nanoparticles, the resistivity of ECAs could be reduced to 1/3000 of that of ECAs with the same silver content, showing great promise in next-generation ECA products.

“…Polymer latexes are polymer particles that are dispersed in water and are widely used in the coating industry − along with other applications as a water born composites, ,− particularly as paper and paperboard coatings. For example, non-biodegradable polymers (e.g., styrene–butadiene latexes) are widely used for such purposes, but they are neither biodegradable nor recyclable. , Compostable polylactide (PLA) latex has been tested as a coating material for paper substrates, but these coated papers do not biodegrade in soil or marine environments.…”

Reported herein is waterborne poly(butylene succinate) (PBS)-coated paper as a potential biodegradable packaging material. Kraft paper was coated with PBS latex, and the coated paper was evaluated for its water and oil repellency, water vapor barrier performance, and physicomechanical properties. The water resistance (Cobb1800 value = 15.5 ± 0.1 g/m2), oil resistance (kit rating = 12/12), and water vapor transmission rate (112.62 ± 8.04 g/(m2 day) were observed for the coated paper. In addition, the coated paper showed excellent thermal sealing properties. Furthermore, a comparative performance study of our coated paper was performed against multiple commercial benchmarks. The PBS-latex-coated paper showed kit rating performance that matched or surpassed those of commercial benchmarks while having better water resistance than at least two tested commercial benchmarks. The biodegradation study in composting conditions indicates that the one-sided coated paper does not potentially affect the overall biodegradation of the coated paper.
