  • Which polyhydroxylated polymers are crosslinked via Ba?
  • Crosslinking mechanism of polyhydroxylated polymers via BA. Polysaccharides, such as dextrin , cellulose , guar gum [20, 109], starch , konjac glucomannan , and scleroglucan , are crosslinked via BA. The crosslinking degree is pH and temperature-responsive.
  • What is cross-linked polymer gel?
  • Cross-linked polymer gel has been broadly used to plug severe lost circulation and to improve the strength of the near-wellbore in natural fracture or carbonate cave strata. Gelation time and gel strength are the key factors for gel plugging.
  • How does crosslinking occur between PA and natural polymers?
  • Crosslinking between PA and natural polymers happens mainly via electrostatic interactions between phosphate groups and cations belonging to the macromolecules .
  • Do crosslinkers synthesize polysaccharides based on hydrogels?
  • There are many crosslinkers to synthesize polysaccharides and proteins based on hydrogels. In this review, we revisited the crosslinking reaction mechanisms between synthetic or natural crosslinkers and polysaccharides or proteins.
