Polyacrylamide crosslinked by bis-vinylimidazolium bromide for high elastic and stable hydrogels - RSC Advances (RSC Publishing)
A series of ionic compounds 1,n-dialkyl-3,3′-bis-l-vinylimidazolium bromide (CnVIM) are prepared and employed to crosslink acrylamide for polyacrylamide (PAAM) hydrogel preparation via in situ solution polymerization. The swelling behavior,
Polyacrylamide hydrogel (PAH) is an extensively cross-linked polymeric soft tissue filler substance, that has been used in the Ukraine, Russia, and Cooking for the past 15–20 years (Christensen et al., 2003; Christensen and Breiting, 2006 ). It
Swelling behavior and network characterization of hydrogels from linear polyacrylamide crosslinked with glutaraldehyde - ScienceDirect
Polyacrylamide hydrogels have been prepared by crosslinking reaction between linear polyacrylamide (PAAm) and glutaraldehyde (GA) in acidic medium. The equilibrium swelling degree, modulus of elasticity and structure parameters of the network
As the hydrogel formation takes place in aqueous media, the use of nanostructured materials is, in principle, limited to water soluble/dispersible entities. Ideally, the preparation of graphene

Cells in aggregation exhibited healthy cell phenotypes and functions, and also the mitosis of the cells in aggregation is exactly the same with the cells in tissue. It is concluded that cell proliferation, aging, and death can be controlled by
Polyacrylamide
Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). 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
The term “polyacrylamide” is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which
- Can cationic polyacrylamide be used for oily wastewater treatment?
- Zhao C, Zheng H, Gao B, Liu Y, Zhai J, Zhang S, Xu B (2018) Ultrasound-initiated synthesis of cationic polyacrylamide for oily wastewater treatment: Enhanced interaction between the flocculant and contaminants.
- What is cationic polyacrylamide?
- Cationic polyacrylamide is projected to be the fastest-growing segment during the forecast period, due to the increasing usage of cationic polyacrylamide in various applications in diverse industries, such as additives in building & construction, color removal and desalination in wastewater treatment, and cell separation in biotechnological broths.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- What are the applications of polyacrylamides?
- Polyacrylamides are used in various applications, such as water treatment, enhanced oil recovery, pulp & paper, and mineral processing. Water treatment was the largest segment of the market, owing to the increasing demand for polyacrylamide from the water treatment industry.
