    Abstract: An aerogel and drying method, the aerogel having a larger size, good productivity, and high transparency. The aerogel has a silsesquioxane structure and exhibits two exothermic peaks observed in a temperature range of 300 to 600° C. as measured by TG-DTA (thermogravimetry-differential thermal analysis) under an inert gas atmosphere containing 80% by volume of an inert gas and 20% by volume of oxygen. A method for producing aerogel includes a drying step including a first step in which an aerogel which has undergone condensation of a hydrolysate is placed in a liquid phase system having a first liquid phase and a second liquid phase; a second step in which a first solvent constituting the first liquid phase is evaporated from the first liquid phase at a temperature greater than room temperature; and a third step in which heating is still continued after the first liquid phase is evaporated off.

    Abstract: The present invention features a method for the formation of superporous hydrogels using an ion-equilibration technique. Anionic polysaccharides are included in the hydrogel reaction mixture and cations are introduced either during or after hydrogel formation. Properties of the resulting hydrogel can be subsequently adjusted by treating the cation-complexed gel with a different cation or cation mixture under equilibrating conditions. It has been found that by properly adjusting the cations and the sequence in which they are used in the equilibration process, superporous hydrogels can be formed that are highly absorbent while maintaining favorable structural properties, including strength, ruggedness, and resiliency. It has also been found that applying appropriate dehydration conditions to them after their formation can further stabilize the superporous hydrogels formed by the method of the invention.
