  • What is polyacrylamide hydrogel (PAHG)?
  • Polyacrylamide hydrogel (PAHG) Bulkamid ® is a sterile gel consisting of 2.5% cross-linked Polyacrylamide and 97.5% non pyrogenic water [ 4 ]. PAHG has been used extensively in plastic surgery and has been shown to be biocompatible, non- toxic, and non- resorbable [ 5, 6, 7 ].
  • What is a polyacrylamide hydrogel?
  • Polyacrylamide is a well-known hydrogel whose swelling capacity is not very sensitive to pH or electrolytes. Polyacrylamide hydrogels are usually synthesized in aqueous solution using water-soluble initiators and crosslinking agents such as N,N ′-methylenebisacrylamide [5, 17].
  • 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.
  • Which polymer is used to prepare acrylic acid hydrogel?
  • Free radical polymerisation is commonly used to prepared acrylic acid hydrogel since acrylic acid can easily react with the electrophilic agent and free radicals . Acrylic acid (Fig. 1) is a monomer that is cross-linked to produce hydrogels with high water absorbing capacity as a single or multi-component system.
