6.5.7.3 Surface Grafting
Surface modification is one of the most important
technologies for the preparation of multifunctional
biomaterials. Surface modification techniques include
coating, blending, and grafting.
Graft polymerization is performed most frequently
using the following methods [92]:
• Surface-initiated graft polymerization or grafting
from methods in which the monomers are poly-
merized from initiators or comonomers, and
• Adsorption of the polymer to the substrate or
grafting to methods, such as reaction of the end
groups of the ready-made polymers with the func-
tional groups of the substrate.
The grafting fr
