Some hydrogels having novel molecular structures

a b s t r a c t Hydrogels are important materials for a variety of applications, particularly biomedical devices, but they generally have poor mechanical properties since they consist predom- inantly of water held in place by a relatively fragile polymer network. This brief review describes a few novel methods to control or improve the mechanical properties of hydro- gels including slide-ring gels, double-network gels, nanocomposite gels, and photoactive gels.Ourgoalistoencouragemoreresearcherstobeawareofandtoexploitthesemethods.
