“…Zhao et al presented a simple approach to fabricating nanocomposites by constructing coupled clusters of short hydrogen bonds between polyborosiloxane (PBS) and L-cystine-modified MMT nanosheets, resulting in weak entanglement and interfacial interactions, see Figure 3 . Remarkable barrier properties (WVP ~4.74 × 10 −11 g·m/(m 2 ·s·Pa) was achieved even after repeated damage-healing cycles [ 46 ].…”

Biodegradable polymers have become a topic of great scientific and industrial interest due to their environmentally friendly nature. For the benefit of the market economy and environment, biodegradable materials should play a more critical role in packaging materials, which currently account for more than 50% of plastic products. However, various challenges remain for biodegradable polymers for practical packaging applications. Particularly pertaining to the poor oxygen/moisture barrier issues, which greatly limit the application of current biodegradable polymers in food packaging. In this review, various strategies for barrier property improvement are summarized, such as chain architecture and crystallinity tailoring, melt blending, multi-layer co-extrusion, surface coating, and nanotechnology. These strategies have also been considered effective ways for overcoming the poor oxygen or water vapor barrier properties of representative biodegradable polymers in mainstream research.

“…[27][28][29] The B O crosslinking bonds will break down and continuously reorganize in this condition, resulting in even better resistance to disentanglement and increasing the material's stiffness. When a crucial strain rate reaches, a second phase transformation will take place, going from a rubber to a glassy state [30][31][32] (Figure 1B(b-e)). The different mechanisms of STG can be attributed to the chemical nature of the materials.…”

Shear thickening gel (STG) is a promising substrate used for flexible protective materials, which has superior dimensional stability without gel side leakage and delamination when sustaining long-standing time. STG/high-performance fiber flexible composites exhibit high-energy absorption capacity for multivelocity impact. This article reveals the shear thickening mechanism of STG that lays a theoretical foundation for the performance analysis of STG composites. The preparation methods of STG/high-performance fiber flexible composites, including impregnation, hand lay-up, filling, and lamination methods, are compared. The energy absorption principle of STG/high-performance fiber flexible composites on multi-velocity impact and the destruction morphology was analyzed. The coupling effects and functional applications of STG functional composites with nanoparticles, magnetic particles, and conductive particles are summarized. It provides more suitable conditions for designing new multifunctional protective equipment and manufacturing advanced intelligent, protective devices.

Food packaging materials are often inevitably and imperceptibly damaged during the transportation, handling, and storage, and the disruption of their integrity poses a challenge to food preservation. Food packaging materials with self‐healing capability can automatically repair the damaged areas and reconstruct original properties to avoid degradation of food quality and loss of nutrients. Various self‐healing materials based on dynamic covalent bonds and/or dynamic non‐covalent interactions have been developed and applied in food packaging in the forms of films and coatings at laboratory scale, and more efforts are required for the commercialization of these novel smart packaging materials. This is the first review to summarize the recent progress in the preparation of self‐healing packaging materials through different mechanisms, compare the self‐healing efficiency under different conditions, and highlight the potential applications of self‐healing films and coatings with recoverable mechanical and barrier properties and other functionalities (e.g., antimicrobial and anti‐fogging capacities). Finally, the future opportunities and challenges of applying self‐healing materials in food packaging are described.
