Polyacrylamide - Wikipedia
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.
Super-Absorbing Polymer Powder - Carnegie Mellon University
Sodium polyacrylate has fewer cross-links, and therefore can absorb more water than the PolySnow™. PolySnow™ gets its name from the fact that, within a certain concentration range, it absorbs water to form not the usual gel, but white particles that resemble snowflakes.
Sodium alginate-g-polyacrylamide hydrogel for water retention …
2 天之前 · To the best of our knowledge, this is the first report on using alginate grafted with polyacrylamide as a water retainer to enhance survival and growth and to describe the physiological response of Eucalyptus nitens seedlings under both well-watered and water-deficient soil conditions.
Polyacrylamide hydrogel is widely used in ophthalmic operations, drug treatment, food packaging products, and water purification.This review describes the various methods of synthesis of polyacrylamide based hydrogel; characterization of polyacrylamide based hydrogel by D.S.C
Recently, materials with the ability to absorb water in high amounts are again under investigation, because of their potential applications in communication technology, building industry, chromatography, water purification and agriculture (1-7).
Superabsorbent polymers used for agricultural water retention
2021年2月1日 · Polyacrylicacid (PAA) and sodium polyacrylate (PNaA) SAPs are the most widely used water retention agents as a result of superior water absorbency (300–500 g/g in water) and water retention capacity.
The resulting polyacrylamide was saponified with NaOH solution. The hydrolysed polymers show high degree of water swelling (> 500) than that of unhydrolysed polymers (< 100).
Measurement of polyacrylamide polymers in water and …
2014年6月1日 · Measurement of polymers in water and wastewater is a major challenge, and there is currently no quick and simple method that can achieve this. This study presents a method for quantification of polyacrylamide concentration using an in-line UV–vis spectrophotometer that can generate real-time data.
Research Advances in Superabsorbent Polymers - MDPI
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.
Hydrosource - The World's Leading Polymer Water Absorbing …
Hydrosource products also include: granular, tablet, log, and liquid forms of linear polyacrylamide [PAM] for stopping erosion and controlling dust; liquid polyvinyl acetate [PVA] for making temporary roadways; and the entire DeWitt product line, including their famous twenty-year landscape fabrics, as well as garden drip irrigation and ...
