Chemorheology of Poly (Methacrylamide-co-Acrylic Acid) Gels Crosslinked by Chromium (III) Ions

چکیده
The chemorheology of poly (methacrylamide-co-acrylic acid) gel crosslinked by Chromium (III) (Cr ) III ions was investigated using stress-controlled viscometry techniques. This work showed that between various variables, such as polymer and crosslinker concentrations, salinity, pH and temperature, the later parameter had a significant effect on the idle time and processing time as two critical parameters in proper placement of gelant. The presence of Na had also a retarding effect. The rheological behavior of gelant was in good agreement with + the original Casson model.

متن کاملPoly(vinylphosphonic acid‐co‐acrylic acid) hydrogels: The effect of copolymer composition on osteoblast adhesion and proliferation
There is a clinical need for a synthetic bone graft substitute that can be used at sites of surgical intervention to promote bone regeneration. Poly(vinylphosphonic acid-co-acrylic acid) (PVPA-co-AA) has recently been identified as a potential candidate for use in bone tissue scaffolds. It is hypothesized that PVPA-co-AA can bind to divalent calcium ions on bone mineral surfaces to control matr...

Magnetic poly (acrylonitrile-co-acrylic acid) (PAN-co-AA) composite nanofibers with different proportions of magnetic nanoparticles (MNPs) were fabricated using electrospinning technique. Electrospinning conditions like polymeric concentration, applied voltage, feeding rate, working distance, and collector type were explored and optimized to produce ultrafine- uniform size and bead free nanofib...
متن کاملSwelling and Mechanical Properties of Modified HEMA- based Superporous Hydrogels
Superporous hydrogels (SPHs), based on poly(2-hydroxyethyl methacrylate) (PHEMA), were prepared by adding minute amounts of an ioncomplexable hydrophilic acrylic acid. PHEMA SPHs are generally strong, but their swelling is minimal. To improve the swelling, different poly(HEMA-coacrylic acid) hydrogels were polymerized and crosslinked, then physically treated with divalent calcium and trivalent ...
متن کاملSpeciation of chromium in water samples by solid-phase extraction on a new synthesized adsorbent.
Poly(1,3-thiazol-2-yl methacrylamide-co-4-vinyl pyridine-co-divinylbenzene) was prepared and used as a sorbent for the solid-phase extraction of Cr(VI) ions from aqueous solution. Two forms of chromium showed different exchange capacities at different pH values; Cr(VI) was selectively retained especially at pH 2. The total chromium was determined after the oxidization of Cr(III) to Cr(VI) by po...
