crosslinkers for polysaccharides and proteins: synthesis
the unreacted crosslinkers might remain inside the scaffolds, causing biocompatibility issues. for this reason, crosslinking with natural crosslinkers is an increasing trend. the most frequently used natural crosslinkers are genipin, enzymes, citric acid and tannic acid due to their low toxicity.
polyacrylamide crosslinked by bis-vinylimidazolium bromide,all the bis-vinylimidazolium bromide crosslinkers were prepared by procedures analogous to that described below for c 6 vim. 1,6-dibromohexane (3 ml, 10 mmol) and 1-vinylimidazole (2 ml, 22 mmol) were dissolved in methanol (5 ml). the mixture was stirred at 60 °c for 30 h, then ethyl acetate (50 ml) was added to precipitate resultant bis
on-site cross-linking of polyacrylamide to efficiently bind
herein, polyacrylamide (pam) polymer chains that are premixed homogeneously with various components are cross-linked on-site on the current collector via the condensation reaction with citric acid, forming a polar three-dimensional (3d) network with improved tensile properties and adhesion for both silicon particles and current collector.
swelling and mechanical properties of polyacrylamide,polyacrylamide was chosen as a commonly used neutral polymer. imidazole ligands for transient physical crosslinking by metal ligand coordination bonds were introduced by copolymerization with the co-monomer 1-vinylimidazole, which is highly water soluble and commercially available.
research on the crosslinking mechanism of polyacrylamide
resol crosslinked polyacrylamide (pam) hydrogel can be used as the chemical flooding agent in enhanced oil recovery because of its excellent temperature- and salt-resistant properties. it is known
an effective flocculation method to the kaolin wastewater,for pad used as flocculant in kaolin wastewater treatment, the results confirmed that, at optimal conditions, the turbidity and the floc size d 50 could reach to 5.9 ntu and 565.936 μ m
enhancing hydrogel toughness by uniform cross-linking using
incorporating acrylated poss-peg into polyacrylamide hydrogel yields enhanced properties such as toughness of up to 6531 kj m−3 and break elongation up to 9455%, where the length of peg chains
one-pot production of a graft copolymer of cationic polyacrylamide.abstract. a newly developed, high-performance, and environmentally friendly flocculant, i.e., a graft copolymer of cationic polyacrylamide and cationic polyacrylamide (sc-cpam), is synthesized via a single-step pathway in which the cationic agent is incorporated onto the starch backbone and into the polyacrylamide grafted branch simultaneously.
mechanical properties of a reversible, dna-crosslinked
mechanical properties of a polyacrylamide gel with reversible dna crosslinks are presented. in this system, three dna strands replace traditional chemical crosslinkers. in contrast to thermoset chemically crosslinked polyacrylamide, the new hydrogel is thermoreversible; crosslink dissociation without the addition of heat is also feasible by
degradation and transfer of polyacrylamide based flocculent,at the molecular level, flocculants can be mineral polymers or natural organic polymers, but synthetic organic polymers constitute the main flocculants. generally, they are anionic polyacrylamide produced by polymerisation of acrylamide and the anionic co-monomer, the sodium acrylate.
