General Properties of Hydrogels
In the application areas of polymer hydrogels, precise information on their molecular constitution as well as their elastic properties is required. Several interesting molecular features control the elastic properties of the hydrogels. In this chapter, we describe general properties of hydrogels formed by free-radical crosslinking copolymerization of vinyl/divinyl monomers in aqueous solutions....
متن کاملAntifouling properties of hydrogels.
Marine sessile organisms easily adhere to submerged solids such as rocks, metals and plastics, but not to seaweeds and fishes, which are covered with soft and wet 'hydrogel'. Inspired by this fact, we have studied long-term antifouling properties of hydrogels against marine sessile organisms. Hydrogels, especially those containing hydroxy group and sulfonic group, show excellent antifouling act...
متن کاملDifferent States of Water in Hydrogels?
Atomistically detailed molecular dynamics simulations of a hydrogel of poly(vinyl alcohol) have been performed. These have been analysed for the water mobility at 250, 300 and 375 K. Only the re-orientation at 250 K but not the translation of the water molecules shows a bimodal distribution of correlation times which may be interpreted by the existence of two different dynamical states of water...
متن کاملViscoelastic Properties of Polyacrylamide Nanocomposite Hydrogels Prepared in Electrolyte Media: Effect of Gelant Volume
In this work, nanocomposite (NC) hydrogels based on polyacrylamide/chromium triacetate were prepared at different reaction mixture (gelant) volumes and their crosslinking process and viscoelastic behaviors were studied. The X-ray diffraction (XRD) patterns taken from the NC hydrogels containing laponite nanoparticles did not show any distinct characteristic basal reflection for all of the NC hy...
متن کاملEmerging properties of hydrogels in tissue engineering
Hydrogels are three-dimensional polymeric networks filled with water and mimic tissue environments. Therefore, they are considered optimal to deliver cells and engineer damaged tissues. The hydrogel networks have been significantly modified to endow biochemical functionality with adhesive ligands, growth factors, or degradable sites that are helpful to drive proper cell functions. Recently, som...
