Abstract
An ionic liquid ion source can include a microfabricated body including a base and a tip. The body can be formed of a porous material compatible with at least one of an ionic liquid or room-temperature molten salt. The body can have a pore size gradient that decreases from the base of the body to the tip of the body, such that the at least one of an ionic liquid or room-temperature molten salt is capable of being transported through capillarity from the base to the tip.
Claims20
A method of forming an electrospray emitter comprising:
- pouring a gel solution into a mold shaped to form one or more emitter bodies with a base and a tip;
- and
- drying the gel solution in the mold to form the one or more emitter bodies at least partially from a porous material.
A method of forming an electrospray emitter comprising:
- pouring a slurry including ground porous material into a mold shaped to form one or more emitter bodies with a base and a tip;
- freezing the slurry in the mold to form a frozen slurry;
- and
- drying the frozen slurry to form the one or more porous emitter bodies.
