Structured macroporous hydrogels that have controllable porosities on both the nanoscale
and the microscale offer both the swelling and interfacial properties of bulk hydrogels as well …

Superabsorbent polymer (SAP) materials are hydrophilic networks that can absorb and
retain huge amounts of WATER or aqueous solutions. They can uptake WATER as high as …

A new type of mining fire-extinguishing material designed to prevent the spontaneous
combustion of coal is presented. Through the graft copolymerization of corn straw, 2 …

Novel superabsorbent hydrogels were prepared successfully from carboxymethylcellulose
sodium (CMC) and cellulose in the NaOH/urea aqueous system by using epichlorohydrin …

Superporous hydrogels (SPHs) are different from superabsorbent polymers (SAPs) in that
SPHs swell fast, within minutes, to the equilibrium swollen state regardless of their size. The …

Cellulose is the most abundant and renewable source for hydrogel production and has
much attention and research attraction in the last two years. Cellulose has intellectual …

A novel chitosan-g-poly (acrylic acid)/attapulgite superabsorbent composite with water
absorbency of 159.6 gg− 1 in distilled water and 42.3 gg− 1 in 0.9 wt% NaCl solution was …

Pore size and thickness of pore walls in macroporous polyacrylamide gels, so-called
cryogels (pAAm-cryogels), were controlled by varying the content of monomers in the initial …

Macroporous gels find application in several scientific fields, ranging from art restoration to
wastewater filtration or cell entrapment. In this work, two-component sponge-like cryogels …

Macroporous gels (MGs) with a broad variety of morphologies are prepared using the
cryotropic gelation technique, ie gelation at subzero temperatures. These highly elastic …
