In Situ Crosslinking of PEI and Isocyanate for Enhanced Moisture Resistance of Ammonium dinitramide：Computational and Experimental Investigation

Key Points

• This research aims to improve the moisture resistance of ammonium dinitramide using a novel crosslinking approach.
• Developed a surface coating strategy using in situ crosslinking of polyethyleneimine with isocyanates (MDI/TTI).
• Conducted both computational and experimental investigations to evaluate moisture resistance.
• Analyzed the hygroscopicity of treated versus untreated ammonium dinitramide.
• Significant reduction in hygroscopicity observed after crosslinking (exact metrics not specified).
• Enhanced moisture resistance leads to improved stability of ammonium dinitramide under humid conditions.
