Super Absorbent Polymer | Water Absorbent Polymer | Agri Hydrogel

What is Agrihydrogel. AGRI HYDROGEL is generally composed of a 3-dimensional polymer network structure which is a range of superabsorbent anionic polyacrylamide polymers. Co-polymers of acrylate and acrylamide are cross-linked and are water soluble. These become gel on absorbing water and have a capacity of absorbing distilled water up to 350

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Double-Network Tough Hydrogels: A Brief Review on Achievements

This brief review attempts to summarize research advances in the mechanical toughness and structures of double-network (DN) hydrogels. The focus is to provide a critical and concise discussion on the toughening mechanisms, damage recoverability, stress relaxation, and biomedical applications of tough DN hydrogel systems. Both conventional DN hydrogel with two covalently cross-linked networks

Commercial hydrogels for biomedical applications - PMC

The term hydrogel was first coined by Van n Bemmelen in 1984 (van Bemmelen, 1894). Later in the year 1960, Wichterle and Lim reported about hydrogels based on poly (2-hydroxyethyl methacrylate), and they suggested hydrogels can be used as filler after enucleation of the eye, manufacturing of contact lenses and arteries (Wichterle and Lim, 1960).

Chitosan- and Alginate-Based Hydrogels for the Adsorption of Anionic

Novel hydrogel systems based on polyacrylamide/chitosan (PAAM/chitosan) or polyacrylic acid/alginate (PAA/alginate) were prepared, characterized, and applied to reduce the concentrations of dyes in water. These hydrogels were synthetized via a semi-interpenetrating polymer network (semi-IPN) and then characterized by Fourier transformed infrared spectroscopy (FTIR) and thermogravimetric
