The complexation of metal ions with polymer hydrogels has been studied. For the study, polyelectrolyte based on hydroxyethyl acrylate, acrylic acid, and chitosan were synthesized, surface which various metals chemisorbed formation chelate complexes. complex compounds hydrogel divalent trivalent was confirmed by data IR spectra. dynamics swelling a copolymer acid acrylamide It found that coeffic...

We investigate the dewetting of aqueous, evaporating polymer [poly(acrylic acid)] solutions cast on glassy hydrophobic (polystyrene) substrates. As in ordinary dewetting, the evaporating films initially break up through the nucleation of holes that perforate the film, but the rapidly growing holes become unstable and form nonequilibrium patterns resembling fingering patterns that arise when inj...

A polymeric coating was enlarged by incorporating carbon-based nanofiller such as graphene (GR), oxide, chopped carbon fibers (CF), etc., into the polymer to be utilized for various technological applications. In this framework, acrylic composites and hybrid coatings were made casting a combination of polymer, GR, CF at room temperature. The hybrids composed different ratios (0.25, 0.5, 1, 2 wt...

In this paper, the synthesis of new montmorillonite nanocomposite hydrogel (MMTNH) based on poly (acrylic acid-co-acrylamide) grafted onto starch, is described. Montmorillonite (MMT) as nanometer base, acrylic acid (AA) and acrylamide (AAm) as monomers, ammonium persulfate (APS) as an initiator, N,N-methylenebisacrylamide (MBA) as a crosslinker and starch as a biocompatible polymer were pre...
