Breakthrough in Engineering: Researchers Develop Multifunctional Hydrogel for Deflagration-Prone Substances Packaging

Researchers at the College of Bioresources Chemical and Materials Engineering have made a significant discovery in the field of engineering, developing a novel multifunctional hydrogel that overcomes classic functional trade-offs in protective materials. The innovative hydrogel, called Gel Alloy, is prepared via one-step self-assembly at room temperature and exhibits exceptional integrated performance, including flame retardancy up to 1300 °C, high compressive strength, puncture resistance, and durability in saline-wet environments.

Key Takeaways:

• The researchers introduced Gel Alloy, a three-layer hydrogel prepared via one-step self-assembly at room temperature, characterized by its alloy-like stratified complementary structure.
• The resulting Gel Alloy exhibits exceptional integrated performance, including flame retardancy up to 1300 °C, high compressive strength (6.8 MPa), puncture resistance (111.3 MPa), and durability in saline-wet environments.
