“…For ESP-PU-6.1, the compressive strength of the foam is 5.15 kPa and the compressive modulus is 41.64 kPa, while the corresponding values for SP-PU-6.1 are 2.92 and 17.3 kPa, which was improved by 76 and 140%, respectively. The remarkable enhanced mechanical performance in PU from ESP over that of SP-reinforced foam can be attributed to (1) the solubility of ESP in polyols brings the active hydrogen into contact with isocyanate, resulting in the full involvement of macromolecular ESP into the PU skeleton at the molecular level; (2) the existence of abundant amide groups on ESP enables the formation of an intramolecular interaction including hydrogen bonding within the PU matrix, which forms an interpenetrating network that affords an additional toughening effect (Figure d) In contrast, SP cannot be dissolved in polyols that act as a filler in the PU matrix. Although it can improve the modulus to a certain extent, the overall toughening effect is quite limited.…”

“…Meanwhile, although the tensile performance of ESP-PU-6.1 was not as good as that of ESP-PU-2.6, it still showed a 132% increase in tensile strength and a 119% increase in elongation at break compared with SP-PU-6.1. Furthermore, the (2) the existence of abundant amide groups on ESP enables the formation of an intramolecular interaction including hydrogen bonding within the PU matrix, which forms an interpenetrating network that affords an additional toughening effect (Figure 3d) 31 In contrast, SP cannot be dissolved in polyols that act as a filler in the PU matrix.…”

“…At an SPI concentration of 10 and 6%, the maximum and minimum tensile strengths were found to be 3.5 MPa and 1.6 MPa, respectively. Moreover, due to the intrinsic hydrophilicity of proteins, soy protein films offer only a moderate level of resistance to the transport of water vapors [ 41 ].…”

The quality and safety of food products greatly depend on the physiochemical properties of the food packaging material. There is an increasing trend in the utilization of protein-based biopolymers for the preparation of edible films and coating due to their film-forming properties. Various studies have reported the preparation of protein-based edible films with desirable mechanical and barrier properties. The mechanical attributes of the protein-based food packaging materials can be enhanced by incorporating various components in the film composition such as plasticizers, surfactants, crosslinkers, and various bioactive compounds, including antimicrobial and antioxidant compounds. This review article summarizes the recent updates and perspective on the mechanical attributes such as Tensile Strength (TS), Elongation at Break (EAB), and Young’s Modulus (YM) of edible films based on different proteins from plants and animal sources. Moreover, the effects of composite materials such as other biopolymers, bioactive compounds, essential oils, and plasticizers on the mechanical properties of protein-based edible films are also discussed.

“…Given that plasticizers with small molecule tend to migrate to the surface of the membrane, causing contamination of SP film and reduction in mechanical properties, the use of longchain macromolecular plasticizers and hyperbranched plasticizers for plasticization modification of SP film is an effective strategy. [67][68][69] As a result of the hydrogen bonding interaction between long-chain PVA and SP, a sacrificial hydrogen bond network is formed, increasing the toughness of the film to 29.5 MJ m −3 . [70] Polyamide-polyamine compounds (PPC), which are obtained by reacting adipic acid with diethylenetriamine, can form strong intermolecular interactions such as hydrogen bonds or ionic bonds with the substrate, significantly improving the flexibility and ductility of materials.…”

This review aims to provide a comprehensive overview of the research progress on soy protein (SP) film. SP film has gained significant attention due to its natural, renewable, and biodegradable characteristics. The review begins by introducing the film formation mechanisms and preparation methods of SP film, including solution casting, dry‐film formation, and other techniques, and discusses the associated preparation conditions and processes. Subsequently, the review explores the structural features, plasticization modifications, mechanical properties, antimicrobial modifications, UV shielding properties, and conductivity of SP film. Lastly, the review summarizes the current challenges and development directions in SP film research. This includes improving the mechanical performance and stability of the film, exploring novel functionalization approaches, and enhancing the sustainability of the film. Through this review of SP film, the study aims to enhance the understanding of their potential in materials science and various applications while providing guidance and insights for future research and applications.
