Superabsorbent polymer - Wikipedia
网页A superabsorbent polymer (SAP) (also called slush powder) is a water-absorbing hydrophilic homopolymers or copolymers [1] that can absorb and retain extremely large amounts of a liquid relative to its own mass.
Superabsorbent Polymer: Understanding Its Uses and Benefits
网页Superabsorbent polymers (SAPs) are materials with the extraordinary ability to absorb and retain large volumes of water or aqueous solutions, swelling to many times their original size. These cross-linked polymers turn water into a gel-like substance by forming hydrogen bonds with water molecules.
Superabsorbent polymer characteristics, properties, and ...
网页2020年7月30日 · Superabsorbent polymers are a network of polymer chains where water is drawn into the polymer through the process of osmosis (Elliott, 2013). Chains contain ions such as COO − and Na + , which induce an osmotic gradient whereby water …
Superabsorbent Polymers: From long-established, microplastics ...
网页2022年2月1日 · Superabsorbent polymers (SAPs) are a kind of synthetic specialty polymers featured by remarkably high water uptake capacity. A typical SAP is highly hydrophilic networks that can imbibe and retain huge amounts of water or aqueous solutions even under pressure [6], [7], [8].
Superabsorbent polymers: A review on the characteristics and ...
网页2019年8月1日 · The current review provides an overview of different types of superabsorbent polymers (SAPs) together with appropriate strategies elaborated to enable their synthesis. The main focus will be on polysaccharide-based, semi-synthetic and ‘smart’ SAPs along with their derivatives.
Research Advances in Superabsorbent Polymers - MDPI
网页2024年2月12日 · Synthetic polymers like polyacrylic acid, polyacrylamide, polyacrylonitrile, and polyvinyl alcohol exhibit superior water absorption properties compared to natural polymers such as cellulose, chitosan, and starch, but they also do not degrade easily.
Development history and synthesis of super-absorbent polymers ...
网页2020年5月6日 · Super-absorbent polymers (SAPs) refer to a three-dimensional network polymer, water-swellable, water-insoluble, organic or inorganic material that can absorb thousands of times its own weight of distilled water.
