Abstract

A self-heating snowmelt composition according to one embodiment of the present disclosure may comprise 70 to 95 weight% of an organic acid salt-based snowmelt main material, 3 to 25 weight% of a bio-based auxiliary material, and the remainder of a photothermal conversion material that absorbs sunlight and converts it into thermal energy. The photothermal conversion material may be one or more selected from the group consisting of carbon black, tungsten trioxide (WO3), triiron tetroxide (Fe3O4), carbon nanotubes (CNT), and polypyrrole.
