A METHOD OF DEPOSITING A COATING WITH VARIABLE TOPOGRAPHY ONTO A POLYMER

摘要

The present invention relates to a method of modifying a surface of a polymer. Specifically, the present invention relates to a method of modifying the topography of a polymer surface comprising the steps of providing a target source;providing a polymer substrate;providing a plasma environment at a specific pressure; sputtering the target source for a specific period; and condensing the sputtered target source at the polymer substrate. The present invention accordingly finds utility, for example, in functionalising a surface of a medical device formed from a polymeric material.
