Synthesis and properties of polyacrylamide by nanoparticles

Brine properties: Preparation of brine: a synthetic brine with20,000 ppm concentration was prepared by dissolving NaCl =1.71, Na2SO3= 0.01, CaCl2= 0.32, MgCl2.6H2O = 0.09 andNa2HCO3= 0.02 percent of weight in distilled water. 2.3.

Oct 15, 2016 · The properties of PS mainly depend on chemical and physical parameters, such as lipophilicity, type and number of charged groups, charge-to-mass ratio, and type and number of ring and core substituents. Most of the classical PSs have poor solubility under physiological conditions, undesirable pharmacokinetics, and low cellular selectivity.

Oct 11, 2016 · Polymeric nanoparticles are synthesized by the induction of polymer on the surface of nanoparticles to form a more stable and highly efficient injectant, with a core of nanoparticles and a...

Preparation and solution properties of polyacrylamide-based

1 Introduction Amphoteric polyacrylamide has both positive and negative charge groups, which has good water solubility. The anion group can protect the cation group and repel the “impurity anion” in the pulp system, so that the cation group will not be reacted or neutralized too early.

RAPTA‐Decorated Polyacrylamide Nanoparticles: Exploring their

ABSTRACT A new hydrogel was synthesized based on polyacrylamide and sodium carboxymethylcellulose. N,N'-Methylenebisacrylamide (MBA) was used as cross- linker and ammonium persulfate (APS) and N,N,N',N'-tetra-methylethylenediamine (TEMED) were utilized as initiators.

Synthesis and properties of polyacrylamide ferrogels filled

Co-polymers used as the matrices were synthesized by radical polymerization of the co-monomers in different mol ratios (1:1, 2:1 and 1:2, DMAEMA:acrylic acid). The presence of the nanostructured CdS was confirmed by TEM analysis as well as by the shift of the onset of the optical absorption towards lower wavelengths.

Synthesis and Mechanical Properties of Polyacrylamide Gel

The polyacrylamide can be chemically modified to make them cationic, anionic or amphoteric. Their hydrophobicity or hydrophilicity can also be controlled by chemical modification or by co-polymerization. They can be made into gels or beads. The monomers can be polymerized in several solvents including water and by inverse emulsion polymerization.
