The research and development of new materials is at the intersection of physics, chemistry and biology, and the core trend is to give materials "life" characteristics, that is, intelligent response and self-healing capabilities. In terms of sustainable polymer materials, chemical recycling closed-loop is the focus of top journals. Researchers have developed new polymers with "depolymerization switches" that can completely depolymerize back to the monomer under specific mild conditions after the end of their service life, thus achieving infinite recycling without loss of performance, and completely solving the pain points of traditional plastics that are difficult to degrade. In the field of smart materials, ion electronics inspired by biological tissues is on the rise. By simulating the ion transport mechanism of the biological nervous system, scientists have developed a highly stretchable, self-healing conductive hydrogel that can act as a human-computer interface to convert bioelectrical signals into digital signals, providing a new physical basis for soft robots and wearable devices. In addition, the structural design of porous crystal materials such as metal organic frameworks (MOFs) and covalent organic frameworks (COFs) has also reached atomic-level accuracy, and their applications in the fields of gas separation, catalysis and energy storage are moving from laboratories to industrialization, redefining the functional boundaries of materials.
