Photochemical modification of polymers for medical purposes (review)

The basic procedures of controlled modification of the polymeric material surface structure and composition are considered in order to obtain required properties of the material. High efficiency of UV-radiation used to modify polysiloxane materials being applied in ophthalmology, is shown. Nature and character of the changes in surface structure and silicone material properties are revealed. Many-sided approach to the analysis of material modification allows choosing optimal technology providing a high biological coexistence, along with meeting other requirements.
