“…However, the healing effect was not verified in detail. In addition, Wu and co‐workers [ 185 ] reported a cellulose‐polydopamine‐poly (acrylamide) hydrogel (Cel‐PDA‐PAM) based separator for SC, in which the hydrogen bonding and π–π stacking of the catechol groups in PDA provided strong mechanical and self‐healing properties.…”

The booming development of electronics, electric vehicles, and grid storage stations has led to a high demand for advanced energy‐storage devices (ESDs) and accompanied attention to their reliability under various circumstances. Self‐healing is the ability of an organism to repair damage and restore function through its own internal vitality. Inspired by this, brilliant designs have emerged in recent years using self‐healing materials to significantly improve the lifespan, durability, and safety of ESDs. Extrinsic and intrinsic self‐healing materials and their working principles are first introduced. Then, the application of self‐healing materials in ESDs according to their self‐healing chemistry, including hydrogen bonds, electrostatic interactions, and borate ester bonds, are described in detail. Based on these, critical challenges and important future directions of self‐healing ESDs are discussed.

“…Aerogels are ultralight materials with porous structure that are produced by replacing the liquid component in the gel by gas. Due to their fascinating characteristics such as low density, light weight, high specific surface areas, and high porosity, aerogels are now regarded as the most promising solid material and are widely applied as pollutants sorbents for environmental remediation applications, piezoresistive sensors, catalyst supports, fire retardants, supercapacitors, microwave absorbing materials, and so on. Based on their components, aerogels are classified as molecular aerogels, inorganic aerogels, and organic aerogels .…”

exhibit strong advantages in providing diverse mechanical properties, such as varying from stiff to high elasticity to enable adaption to a wide range of demands.While the application of aerogels in smart materials has attracted increasing attention, ensuring full functionality in a porous structure is still highly challenging. As one of the booming smart materials, shape-memory polymers (SMPs) have been intensively investigated, and numerous multiresponsive, [20][21][22][23][24][25] multifunctional shape memory polymeric bulk materials [26][27][28][29] or hydrogels [30][31][32][33][34][35] have been developed. However, to the best of our knowledge, there have been very few reports about shape memory aerogels. [36,37] Rowan and coworkers [38] developed a thermal responsive shape memory aerogel from a thiol-ene network with a glass temperature above room temperature, and showed that it displays very good shape memory performance. However, this shape memory aerogel is produced from an organogel. Generally, fabricating aerogels from hydrogels is a more economical and eco-friendly strategy.Herein, we seek to develop a shape memory polymeric aerogel (SMPA) from the corresponding hydrogel via an eco-friendly strategy by choosing water soluble and highly matchable constituent materials. It is well-known that crystalline poly(ethylene glycol) (PEG) with a melting temperature (T m ) above room temperature is a favorable component for the development of thermally induced SMPs, and its water solubility makes it a good candidate for SMPA. However, the aerogel formed from a single highly crystalline PEG component will show a poor mechanical performance. To address this problem, we considered chitosan (CS) which is a biobased material derived from sustainable resources. CS is obtained by deacetylation of chitin and its physicochemical properties are determined by the degree of deacetylation and molecular weight. [39] It was identified as a good start material for fabricating aerogels with unique advantages, such as good flexibility, nontoxicity, cost-effectiveness and biodegradability. Thus, CS was chosen as the other precursor material to enhance the aerogel skeleton. In this work, we prepared a shape memory aerogel based on chitosan/poly(ethylene glycol) diacrylate (CS/PEGDA) semi-interpenetrating networks (semi-IPNs) via a facile one-pot photocrosslinking approach. The feed ratio of CS and diacrylic PEG (PEGDA) precursors with different molecular weights were tuned to Shape-Memory Aerogels While the field of shape memory polymers (SMPs) has developed rapidly, it is still highly challenging to obtain SMPs in the form of aerogels (SMPAs) due to the unique technique used for the fabrication of the aerogels and their high porosity. Herein, a thermally induced SMPA based on chitosan/poly(ethylene glycol) diacrylate (CS/PEGDA) semi-interpenetrating networks is reported that are produced using an eco-friendly strategy. The main network is responsible for the shape memory effect (SME) and can be easily tuned by varying the feed rat...

“…8 Therefore, aerogel can be regarded as a state of matter with similar porous structure to solid networks of a gel with gas or vacuum in-between the skeletons. 9 Due to the outstanding physicochemical properties, diverse aerogels have been developed and recognized as promising candidates for various applications, such as thermal insulation, 10 photocatalysts, 11 sensor, 12,13 supercapacitor, 14,15 and water treatment. 16 Presently, clinical treatments have impressively requirements on the generation of functional biomaterials with designable structures.…”

Biomaterials with porous structure and high surface area attract growing interest in biomedical research and applications. Aerogel-based biomaterials, as highly porous materials that are made from different sources of macromolecules, inorganic materials, and composites, mimic the structures of the biological extracellular matrix (ECM), which is a three-dimensional network of natural macromolecules (e.g., collagen and glycoproteins), and provide structural support and exert biochemical effects to surrounding cells in tissues. In recent years, the higher requirements on biomaterials significantly promote the design and development of aerogel-based biomaterials with high biocompatibility and biological activity. These biomaterials with multilevel hierarchical structures display excellent biological functions by promoting cell adhesion, proliferation, and differentiation, which are critical for biomedical applications. This review highlights and discusses the recent progress in the preparation of aerogel-based biomaterials and their biomedical applications, including wound healing, bone regeneration, and drug delivery. Moreover, the current review provides different strategies for modulating the biological performance of aerogel-based biomaterials and further sheds light on the current status of these materials in biomedical research.
