  • 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.
  • How is poly (acrylamide-co-acrylic acid) hydrogel prepared?
  • According to Seddiki et al. poly (acrylamide-co-acrylic acid) hydrogel was prepared by free radical polymerisation and its rheological behaviour was measured by using Rheometer AR-2000 in controlled stress and under oscillatory shear . Under the oscillatory conditioning, the experiment was done at 6.2 Hz.
  • What are polymeric hydrogels used for?
  • Polymeric hydrogels have wide applications including electrophoresis, biocompatible materials, water superadsorbents, and contact lenses. The properties of hydrogels involve the poorly characterized molecular dynamics of water and solutes trapped within the three-dimensional cross-linked polymer networks.
  • What are superabsorbent hydrogels based on acrylic acid and acrylamide?
  • Superabsorbent hydrogels based on acrylic acid and acrylamide are mainly focused on since these hydrogels have been used for various applications in biomedical and tissue engineering. Acrylic acid and acrylamide are among the main materials used in the synthesis and preparation of hydrogels.
