Abstract
Absorbent composites are described as containing a particle of superabsorbent material covered with an energy receptive additive. The absorbent composites are suitable for exposure to dielectric heating, in general, and microwave heating, in particular.
Claims35
An absorbent composite comprising a superabsorbent material and an energy receptive additive, the energy receptive additive having a dielectric loss tangent of at least about 0.15.
An absorbent composite comprising a superabsorbent material and an energy receptive additive, the energy receptive additive having a dielectric constant of at least about 4.
The composite of 15, wherein the dielectric constant is measured at a frequency of about 915 MHz.
A microwave heatable absorbent composite comprising a superabsorbent material and an energy receptive additive, the energy receptive additive (i) being in intimate association with and covering the surface of the superabsorbent material and (ii) heating up in the presence of microwave energy.
