An antistatic composition contains an ambient-temperature molten lithium salt dihydrate, and one of a polymerizable compound, a plastic resin, an elastomer and an adhesive resin in which the lithium salt dihydrate is dispersed. The lithium salt dihydrate contains two types of lithium salts with different molecular weights from each other. The two types of the lithium salts are selected from a group of lithium salts each containing an anion having a fluoro group and a sulfonyl group.

A method of making an adhesive for an ice protection assembly includes mixing ferrous nanoparticles into the adhesive. Removal of the adhesive for ice protection assembly inspection or repair includes heating the ferrous nanoparticles in the adhesive to soften the adhesive and allow for easy removal or repositioning of the ice protection assembly.
