3D Meshlike Polyacrylamide Hydrogel as a Novel Binder
In addition, the effect of the chemical/mechanical properties of PAM gel on the electrochemical properties of Si is adequately elucidated. The results will provide meaningful insight regarding the design of novel binders, especially in the application of the covalently crosslinked structure to Si‐based electrodes.
Polyethyleneimine (PEI) has been used as an organic cross-linker for polyacrylamide tert-butyl acrylate copolymer (PAtBA). Literature reported that PEI can also form ringing gels with polyacrylamide copolymers and simple polyacrylamide homopolymers (PAM).

Novel crosslinking methods to design hydrogels - ScienceDirect
Miyata et al. prepared a hydrogel in which an antigen (rabbit IgG) was grafted to chemically crosslinked polyacrylamide in the presence of antibody as an additional crosslinker . The hydrogel lightly swelled in the presence of free antigen due to the replacement of polymer-bound antigen, resulting in the release of the antibodies and thereby decrease in crosslink density.
Book Description Hydrogels are crosslinked, macromolecular polymeric materials arranged in a three-dimensional network, which can absorb and retain large amounts of water.
The preparation of a novel hydrogel based on crosslinked
The dust suppression gel had excellent wind erosion resistance and could effectively reduce the occurrence of coal dust during coal transportation. The dust suppression gel is used for dust removal in fully mechanized mining face, and its efficiency is more than 9 times that of spraying water.

Dual physically crosslinked healable polyacrylamide
To develop healable hydrogels with excellent mechanical properties is still a challenge topic. In this study, a novel class of physically crosslinked polyacrylamide based nanocomposite hydrogels reinforced with cellulose nanofibers (CNF) were fabricated using radical polymerization, followed by further strengthening through ferric ions via strong ionic coordination interactions between Fe3
PAM/PPy hydrogel was synthesized via free-radical polymerization of acrylamide using ammonium persulfate (APS) as initiator in the dispersion of PPy nanoparticle. N,N’-methylenebisacrylamide (MBA) and N,N,N’,N’-tetra-methylenediamine (TEMED) were utilized as cross-linker and accelerator, respectively.

Self-gelling hydrogels based on oppositely charged dextran microspheres 41 1. Introduction Hydrogels are an important class of materials that have been studied extensively in the last decades for the controlled release of pharmaceutical proteins, and for tissue engineering applications.
- Why is polyacrylamide used in water treatment?
- With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.
- What is polyacrylamide (PAM) used for?
- npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
- How are polyacrylamides treated?
- The top left is the filter, the top right is the reservoir, and bottom left and bottom right are settling tanks. Polyacrylamides are typically addressed through various treatment methods, including membrane filtration, thermal distillation, oxidation treatment, and biological removal (Table 2).
- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
