Composite Aerogel Comprised of Sodium Alginate and Bentonite via Supercritical CO2 Drying: An Efficient Adsorbent for Lysozyme

Abstract: To meet the demand for the separation of specific substances, the construction of porous composite aerogels with a high specific surface area and a strong adsorption capacity is still a challenge. Herein, a sodium alginate/bentonite composite aerogel was efficiently prepared through supercritical fluid drying. The aerogel’s volume shrank less during supercritical drying, maintaining its original three-dimensional mesh structure. The resulting aerogel had a large specific surface area (445 m2/g), a low density … Show more

“…This trend of material strength variation may be due to the enhanced viscosity of the emulsions, resulting in pore deformation. Nevertheless, the good elasticity and toughness of the material were reflected, and the stress–strain curves of SHC 0.1 are depicted in Figure 3 d. After 200 cycles of compression at 70% strain, it could still recover its original shape without cracking ( Video S1 ), and the as-prepared monolith reflected favorable mechanical properties compared to those of polysaccharide-based composite aerogel [ 22 ]. At the same time, the test result exhibited a typical stress–strain curve for the foam materials.…”
