Non-solvent preparation of polyurethane adhesive with capabilities of shape adaptive, harsh environment resistance and cryogenic durability

Key Points

• Shape adaptive polyurethane adhesives show significant resistance to harsh environments and cryogenic temperatures, enhancing their utility.
• Key performance metrics indicate a reduction in degradation at cryogenic conditions, which supports their application in extreme settings.
• Non-solvent preparation method develops adhesives without traditional solvents, minimizing environmental impact while maintaining adhesive properties.
• Further research may enable broad applications in aerospace and automotive industries, particularly under extreme conditions.
