What is ionic gel in chemistry?

Answer 1

A gel is a substance this is mostly a liquid, but behaves as a solid due to cross-linking bonds (usually due to polymerization) that exists in the overall structure.

To show the contrast, a solid is usually a substance held in some sort of crystalline form (be it due to ionic, covalent, or hydrogen bonds), which makes the overall structure rigid, so that it does not flow.

Whereas, the molecules in a liquid can flow much more easily, moving past each other, and they are not locked in a crystalline form.

In a gel, however, while the molecules can flow past each other, in the absence of external forces, they usually tend to lock into place, weakly bonded to one another, resulting in zero flow. When you add external forces (compression, shearing, etc.), the molecules can move past each other again, and the substance can flow.

Imagine Gelatin (Jello, etc.) as an example. Without any external forces, it sits in place, locked into a molded form. However, if you press or squeeze it, it can easily deform. If you have it in a large container with a plunger behind it, and a smaller opening at the end, you could push the plunger, and the gelatin will extrude from the small opening, allowing it to flow through that opening. "Flow" being the key word here.

The same goes for gel deodorants. They are normally in one form. When you add shear forces, rubbing it on your skin, it will flow from the seemingly solid form to smear onto your skin much like a liquid.

Answer 2

The ionic gel is an alternative to electrodes.
Ionic gel permit ions transport not electrons transport.
