Abstract
Aiming at the mechanism,regularity characterization,influence factors and inhibition of ingredient migration in pro-pellants,gun propellants and explosives,the ingredient migration theories which are mainly driven by concentration gradient and polarity action were introduced.The characterization methods of migration ingredients amount and migration ability based on advanced analytical techniques and migration kinetics were summarized.The effects of temperature,intermolecular interac-tions,crosslinking density,steric hindrance,structure,and other factors on ingredient migration were elaborated.The migra-tion inhibition methods including chemical synthesis,material modification,and additive methods were discussed.The develop-ment directions of establishing rapid and non-destructive characterization methods of ingredient migration,improving migration models and synthesizing new ingredients with high anti-migration performance were proposed.Attached with 79 references.
