Hydrogels - A Broad Class of Biomaterials

  • Allan S. Hoffman
Part of the Polymer Science and Technology book series (POLS, volume 8)

Abstract

The term “hydrogel” refers to a broad class of polymeric materials which are swollen extensively in water (30–90%) but which do not dissolve in water. They have been used in a wide variety and growing number of biomedical applications since they often exhibit good biocompatibility. They may be applied in bulk forms which vary from clear solids to opaque sponges; sometimes these forms are reinforced by woven fabrics since the highly water-swollen gels are mechanically weak. For this same reason, they are also useful as coatings, especially when the biomedical application involves the contact of a preformed device or implant with body fluids. Table I summarizes a number of applications of hydrogels which have been mentioned in the literature (see references also).
