Fluorine-free liquid-repellent coatings have been highly demanded for a variety of applications. However, rapid formation possessing outstanding oil repellency and strong bonding ability as well good mechanical strength (e.g., bendability, impact resistance, scratch resistance) remains grand challenge. Herein, robust strategy to rapidly create fluorine-free oil-repellent in only 30 s via rational design semi-interpenetrating polymer network structure is reported. The resulting coating...
Abstract Conductive hydrogels have recently attracted extensive attention in the field of smart wearable electronics. Despite current versatility conductive hydrogels, balance between mechanical properties (tensile properties, strength, and toughness) electrical (electrical conductivity, sensitivity, stability) still faces great challenges. Herein, a simplified method for constructing hydrophobic association with excellent is proposed. The prepared exhibit high tensile (≈1224%), linearity...
Abstract Real‐time monitoring of respiration plays a very important role in human health assessment, especially and analyzing during exercise sleep. However, traditional humidity sensors still have problems flexibility, sensitivity, durability, so there is an urgent need to develop with high stretchability, environmental resistance as respiratory applications. Here, based on the double network hydrogel structure polyvinyl alcohol polyacrylamide, highly sensitive, stretchable, environmentally...
Durable superhydrophobic anti-erosion/anticorrosion coatings are highly demanded across various applications.

Abstract Environmentally friendly crosslinked polymer networks feature degradable covalent or non‐covalent bonds, with many of them manifesting dynamic characteristics. These attributes enable convenient degradation, facile reprocessibility, and self‐healing capabilities. However, the inherent instability these crosslinking bonds often compromises mechanical properties networks, limiting their practical applications. In this context, environmentally dual‐crosslinking (denoted EF‐DCPNs) have...
