superabsorbent

adj

1. Having the ability to absorb a great amount of fluid relative to its own mass.

   “The water absorbency of the anionically starch-grafted AA/AM absorbent is markedly affected by the pH of the buffer solution at different ionic strengths. The charge of the ionic monomer affects the pH sensitivity of the superabsorbent polymers. An acidic superabsorbent normally ionizes at high pH but unionizes at low pH.”

noun

1. Any superabsorbent substance.
