Effects of hydrogen storage alloy on properties of GAP binder films

In order to study effects of hydrogen storage alloy on the properties of glycidyl azide polymer (GAP) binder films, GAP binder films was made using multi-isocyanate (N100) as curing agent. GAP binder films were characterized by infrared spectroscopy (FTIR), and their curing activation energy, gel fraction and mechanical property were determined. Results show that hydrogen storage alloy reacted with -OH on GAP and formed chemical cross-links; Curing activation energy was reduced and gel fraction was increased to promote, formation of three-dimensional network structure and enhance mechanical property when hydrogen storage alloy was added into GAP binder films. At the dosage of 20%, A30 showed the strongest effect on three-dimensional network structure formation of binder film, decreasing curing activation energy by 27.97%, promoting gel fraction by 5.44%, tensile strength by 131% and elongation by 31%.
