This invention relates to an absorbent composite which utilizes multifunctional superabsorbent materials to enhance distribution of fluids within the absorbent composite. More specifically, this invention relates to superabsorbent materials which swell and absorb fluids and also can deswell and release fluids into the surrounding absorbent composite and towards additional superabsorbent material. The superabsorbent materials of this invention deswell and release fluid by means of a triggering mechanism. Triggering mechanisms can include thermal, chemical, mechanical, electronic, magnetic, and radiation energies. Swelling and deswelling of the superabsorbent materials can be repeated for more than one cycle thereby improving fluid distribution. Multiple swelling and deswelling cycles allow multiple insults to be distributed throughout an absorbent composite, fully utilizing the absorbent capabilities of the full absorbent composite and minimizing leakage.
