摘要
The octadecylamine was selected as a monolayer forming material and xylene as a solvent to increase the surface energy of ammonium nitrate. After monolayer self assembling through hydrogen bonding, Coulomb′s force and polarization action on the interface of xylene/ammonium nitrate, the octadecylamine at a concentration of 2×10 -4 mol/L in xylene can be considered to be self assembled on the surface of ammonium nitrate. The moisture absorption of the ammonium nitrate after surface modification has only 58% of that of the pure ammonium nitrate.
