Grafting of Functional Monomers on Biomaterials
Biointerfaces are seen as a key component when designing new generation biomaterials. In this regard, this chapter aims to illustrate the current status with regards to grafting of functional monomers on polymeric biomaterials including scaffolds and membranes. It will cover the simultaneous grafting method, the peroxy/hydroxyl grafting method, grafting from a surface using controlled radical polymerisation, and plasma polymerisation. Monomers carrying the following functional groups are included: carboxyl, aldehyde, epoxy, amine, phosphate and sulfate. In addition, characterisation of the grafted biomaterials as well as the grafted chains themselves and their position in/on the polymer substrate is described in detail.
