To reduce the electrostatic sensitivity of α-AlH_3,α-AlH_3 w as coated by the solvent-nonsolvent method using stearic acid( SA) as coating material. T he crystal structure and morphology of samples before and after coating w ere characterized by Fourier transform infrared spectroscopy( FT-IR),X-ray diffraction( XRD),X-ray photoelectron spectroscopy( X PS),elemental analysis and scanning electron microscopy( SEM). T he electrostatic sensitivity of α-AlH_3 samples before and after coating w as measured by JGY...
