  • What are the applications of polyacrylamide based hydrogels?
  • In polyacrylamide (Aam) based hydrogels, plenty of applications has been found. Cross-linked polymers which can imbibe a large amount of water can be used in various fields such as biotechnology, biomedical engineering, food industry and separation process.
  • How are polyacrylamide-based hydrogels obtained?
  • Polyacrylamide-based hydrogels were obtained by chemical crosslinking of MBA using acrylamide, sodium carboxymethylecellulose (NaCMC), N,N,N ′, N ′-tetramethylethylenediamine (TEMED) and ammonium persulfate (APS) as the initiators.
  • Are polyacrylamide hydrogels Universal?
  • To demonstrate that our strategy is universal, we used polyacrylamide (PAAm) and poly (2-methacryloyloxyethyl phosphorylcholine) (PMPC) as the main chains of the hydrogels, which have been widely used as representative hydrophilic polymers in various fields and biocompatible zwitterionic polymers in the biomedical field, respectively.
  • How strong is a polyacrylamide hydrogel?
  • By contrast, strength of hydrogels have been less studied. A polyacrylamide hydrogel containing high water content exhibits near-perfect elasticity–that is, the stress-stretch curve has negligible hysteresis ( Yang et al., 2019 ), and is insensitive to strain rate ( Hassan et al., 2025 ).
