Resumo
Gamma radiation has been shown particularly useful for the functionalization
of surfaces with stimuli-responsive polymers. This method involves the
formation of active sites (free radicals) onto the polymeric backbone as a result of
the high-energy radiation exposition over the polymeric material. Thus, a
microenvironment suitable for the reaction among monomer and/or polymer and the
active sites is formed and then leading to propagation to form side-chain grafts. The
modification of polymers using high-energy irradiation can be performed by the
following methods: direct or simultaneous, pre-irradiation oxidative, and pre-irradiation.
The most frequently used ones correspond to the pre-irradiation oxidative
method as well as the direct one. Radiation-grafting has many advantages over other
conventional methods because it does not require the use of catalyst nor additives to
initiate the reaction and usually no changes on the mechanical properties with
respect to the pristine polymeric matrix are observed. This chapter is focused on the
synthesis of smart polymers and coatings obtained by the use of gamma radiation. In
addition, the diverse applications of these materials in the biomedical area are also
reported, with focus in drug delivery, sutures, and biosensors.
