Study on graphene-oxide-based polyacrylamide composite
Graphene, a unique 2D nanocarbon material, has stimulated great interest due to the extraordinary electrical, mechanical and thermal properties [1], [2], [3]. Graphene oxide (GO) acts as an important precursor for graphene-based structure.

The Significance of Graphene Oxide-Polyacrylamide
Here, we study the synergistic interaction of graphene oxide (GO) and a high molecular weight anionic polyacrylamide (PAM) in stabilization of paraffin oil/water emulsion systems. We show that the addition of PAM reduces the amount of GO required to stabilize an emulsion significantly.

Coassembly Kinetics of Graphene Oxide and Block Copolymers
The coassembly kinetics of graphene oxide (GO) nanosheets and diblock copolymers at the water/toluene interface is probed by tracking the dynamic interfacial tension using pendant drop tensiometry. The diblock copolymer significantly enhances the surfactancy of the GO nanosheets at the interface. It is found that diblock copolymers rapidly adsorb to the water/toluene interface and enhance the
Graphene oxide (GO) is an important derivative of graphene, which has been widely used in reinforced composite materials [21], [22], [23]. The surface of GO contains abundant oxygen-containing groups, such as hydroxyl (OH), carbonyl group ( C O).
Bioconjugated graphene oxide hydrogel as an effective
Nowadays, with growing progress in nanoscience and technology, hydrogels based on nanomaterial especially those are based on carbon nanomaterial such as graphene, graphene oxide and carbon nanotubes because of their superior properties have attracted surge of attention among scientists of different fields of researches (Gao et al., 2013; Wang and Chen, 2007). Graphene, a nanocarbon material with layered structure in a hexagonal two-dimensional lattice, has potential applications in many
In the present paper, Graphene Oxide (GO) particles were prepared via Hummer method, and used in synthesis of composite membranes. Polyethersulfone (PES) nanocomposite membranes were synthesized
Polyacrylamide-g-Reduced Graphene Oxide - SpringerLink
To improve the dispersibility of graphene oxide (GO) in solvents, the grafting of polyacrylamide (PAM) from the GO surface was performed by redox polymerization system. The hydrophilic nature and high polarity of PAM have made effective dispersion of GO.
Graphene oxide (GO) have plenty of oxygen-containing groups, which can be used as a gelator to prepare composite hydrogel. Polyacrylamide (PAM), a soluble polymer, can be used as a cross-linker to form composite hydrogels with other gelator.

- Can nonionic polyacrylamide be used as a gel fracturing fluid?
- Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is an anionic polyacrylamide?
- Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
- What is a polyacrylamide gel?
- The polyacrylamide gel is a polymer matrix of acrylamide cross-linked by N,N-methylene-bis-acrylamide (known as bis-acrylamide) as the result of a polymerization reaction between them, induced by tetramethylenediamine (known as TEMED) and carried out by ammonium persulfate (known as APS).
