Strengthening Alginate/Polyacrylamide Hydrogels Using Various
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): ABSTRACT: We successfully synthesized a family of alginate/polyacrylamide hydrogels using various multivalent cations. These hydrogels exhibit exceptional mechanical properties. In particular, we discovered that the hydrogels cross-linked by trivalent cations are much stronger than those cross-linked by divalent cations.

Mechanical strengthened alginate/polyacrylamide hydrogel
Alginate/polyacrylamide hybrid hydrogel has attracted intense interests in different fields, but the low tensile strength and stiffness limit its comprehensive application. In this hydrogel system, the alginate–cation network plays an important role. Thus, based on the unique structure of alginate and its special interaction with different metal cations, we designed a new method of introducing barium and ferric ions together to crosslink the alginate sufficiently, creating a stronger
In the past decade, a huge number of hybrid hydrogels with different structural compositions was reported . Among them, calcium-alginate/polyacrylamide (Alg/PAAm) hydrogel has been widely used in recent years with high toughness and excellent biocompatibility [, , ]. In contrary, a moderate tensile strength (156 kPa) and low stiffness (23 kPa) of Alg/PAAm could be considered as important disadvantageous which may limit its further practical applications.

- Does anionic polyacrylamide biodegrade?
- ent only.1 BACKGROUNDAnionic polyacrylamide is the copolymer of acryl mide and acrylic acid. No studies on the environmental fate of polyac ylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biode rade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concer
- What types of polyacrylamide products can Tianrun chemicals provide?
- Tianrun Chemicals attaches great importance to customer needs, and we can provide five series of polyacrylamide products: anionic, cationic, nonionic, amphoteric, and emulsion according to customer requirements. Tianrun Chemicals is one of the drafters of the national standard for polyacrylamide and drinking water grade polyacrylamide.
- Is anionic Polyacrylamide a chemical of low concern?
- ymer of low concern1 . In addition, based on an assessment of environmental hazards, NICNAS also identified anionic polyacrylamide as a chemical of low concern to the envi onment (NICNAS, 2017). Chemicals of low concern are unlikely to have adverse environmental effects if they are released to the environment from co
- Can anionic polyacrylamide be used in water treatment?
- What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
