Introduction to Bio-Inspired Hydrogel and Their Application

Abstract

This chapter discusses the synthesis, characterization, and application of covalently and physically cross-linked polymers for biomedical application. This class of molecule is called hydrogels and is defined by a covalently bonded polymer matrix that can hold at least two times its mass in solvent. Hydrogels are general classes of polymeric systems that have further subgroups: semi-interpenetrating networks (SIPN), interpenetrating networks (IPN), block co-polymers, and grafted. The different methods to synthesize these hydrogels are discussed. Specific characterization techniques to evaluate the properties and functionalities of the hydrogels are also described in the chapter. Next, the practical and industrial applications of the hydrogels are detailed. Throughout this chapter we will highlight the different synthesis methods, characterization techniques, and current uses of hydrogels. The chapter will be a particularly useful overview and introduction for graduate students and researchers aiming to work in the field of hydrogels.
