“…[463] Intermolecular entanglement and interpenetration can cause the forced miscibility between components, which enable IPNs to integrate the excellent performance of the different participating components. [466,467] Although not strictly IPNs (according to definition), some polymer structures can be classified as IPN-like (pseudo-IPNs), such as AB-type crosslinked polymers (ABCPs) [468,469] (Fig. 15) and thermoplastic IPNs (also called physical crosslinked IPNs) in terms of their structures and preparation methods.…”

Hydrogels are a series of soft and wet materials with three dimensions of crosslinked networks. Hydrogels have attracted great attention due to their diverse functional properties, and their wide range of applications, such as in soft robots and actuators, stretched electronic devices, tissue engineering materials, controlled-release drug delivery vehicles, biomedicine materials, food science, and (bio)sensors. In general, there are four core concerns in hydrogel science, including the polymer source, structure fabrication, gel function, and gel applications. According to the logic that the "structure determines function", it is believed that rational design of structures can effectively regulate the functions and applications of hydrogels. Hence, in the current review, "structure" as the core topic will be highly regarded, and the crosslinking mechanisms and structural diversity of hydrogels are comprehensively summarized. Additionally, hydrogels also show their great application potential in food science. Hence, the current review also pays more attention to the application of hydrogels in food nutrition and health, food engineering and processing, and food safety. It is whished that this review not only serves as a reference for improving the comprehensive understanding of the structural design of hydrogels but also provides a forward-looking idea for hydrogel applications in food science.

Solid‐state batteries (SSBs) have attracted much attention for high‐energy‐density and high‐safety energy storage devices. Solid polymer electrolytes (SPEs) have emerged as a critical component in the advancement of SSBs, owing to the compelling advantages of strong molecular structure‐designability, low cost, easy manufacturing, and no liquid leakage. However, linear SPEs usually have low room‐temperature ionic conductivity due to crystallization, and melting at high temperature. Thus, crosslinked SPEs have been proposed in that the chemical bonding between internal molecule chains can maintain solid state to expand operational temperature, disrupt regularity of segment, and diminish crystalline degree, leading to an enhancement of room‐temperature ionic conductivity. Furthermore, the integration of functional groups within crosslinked SPE network can significantly augment the electrochemical performance of SPEs. Herein, according to the network structure, crosslinked SPEs are categorized into four types: simple network, AB crosslinked polymers (ABCP), semi‐interpenetrating network (semi‐IPN), and interpenetrating network (IPN), then the structure features and advantages and disadvantages of commonly used polymers for these types of crosslinked SPEs are reviewed. In addition, crosslinked SPEs with self‐healing, flame‐retardant, degradable, and recyclability are introduced. Finally, challenges and prospects of crosslinked SPEs are summarized, hoping to provide guidance for the molecular design of SPEs in the future.

Novel AB crosslinked polymer (ABCP) networks were synthesized from telechelic 4‐vinylbenzyl carbamate terminated polyurethanes and monomers such as styrene, 4‐vinylpyridine, methyl methacrylate and butyl acrylate. Telechelic 4‐vinylbenzyl carbamate terminated polyurethanes were synthesized from polypropylene glycol‐based NCO‐terminated polyurethane and vinylbenzyl alcohol. Effect of changing the molecular weight of polypropylene glycol on the static and dynamic mechanical properties of ABCP networks from polyurethane‐polymethyl methacrylate was studied in detail. Dynamic mechanical thermal analysis results show that polymethyl methacrylate and polystyrene‐based ABCPs have good damping over a broad temperature range. ABCP networks prepared from 4‐vinylbenzyl carbamate terminated polyurethane and different monomers such as methyl methacrylate, butyl acrylate and styrene exhibit single tan δmax value which implies excellent interlocking between the two polymers present in the ABCP networks. Static mechanical studies showed that methyl methacrylate and styrene‐based ABCP networks exhibit better tensile properties compared to other ABCP networks from butyl acrylate and 4‐vinyl pyridine monomers. Thermogravimetric analysis results revealed that the ABCP networks showed an improved thermal stability. Copyright © 2009 John Wiley & Sons, Ltd.
