The present invention relates to a shape memory polymer film for a variable antenna of a space structure, and more particularly, to a shape memory polymer film for a variable structure antenna, which comprises 15 to 22 parts by weight of an aromatic diamine as a curing agent and a polyoxypropylene group as an additive As a shape memory polymer film formed by cross-linking a composition comprising 1 to 10 parts by weight of polyetheramine, it is excellent in impact strength, elongation, and recovery rate that returns to the original shape, and is useful as a shape memory member of a variable- And more particularly, to a shape memory polymer film for a variable antenna of a space structure that can be used for an antenna. |
