Introducing superabsorbent polymer (SAP) into white fair-faced concrete can achieve the purpose of internal curing, which is beneficial to popularization and application concrete. The effects SAP mixture curing water content on properties were investigated macroscopically through indexes, including slump, electric flux, standard cube compressive strength, tensile splitting strength. mechanism t...

A hydrophilic macromolecular network is prepared by performing graft copolymerization of poly (sodium acrylate) chains onto salep and silica gel. The reaction parameters affecting the water absorbency of the superabsorbent composite were optimized using Taguchi method. FT-IR spectroscopy and Thermo Gravimetric Analysis (TGA) were used for confirming the s...

This research aims to develop chemical protective clothing via a functionalised surface coating on cotton fabric for simultaneous barrier performance and thermal comfort. An omniphobic layer the was developed through polyurethane – superabsorbent polymer fluoropolymer protect penetration of water, oils liquid chemicals. It found that padding coated specimens with provided substantial improvemen...

The wicking of liquid into a paper-like swelling porous medium made from cellulose and superabsorbent fibers was modeled using Darcy’s law. The work is built on a previous study in which the Washburn equation, modified to account for swelling, was used to predict wicking in a composite of cellulose and superabsorbent fibers. In a new wicking model proposed here, Darcy’s law for flow in porous m...

A novel thermo-sensitive superabsorbent hydrogel with saltand pH-responsiveness properties was obtained by grafting of mixtures of acrylic acid (AA) and N-isopropylacrylamide (NIPAM) monomers onto kappa-carrageenan, kC, using ammonium persulfate (APS) as a free radical initiator in the presence of methylene bisacrylamide (MBA) as a crosslinker. Infrared spectroscopy was carried out to confirm t...
