Abstract
The invention relates to a surface preparation method using a combination of at least two polymers, which are the same or different, which are grafted hierarchically or multiply on a surface, and also to the use of this preparation method, more particularly in applications for controlling the surface energy of a substrate. The invention may allow a block polymer to be structured with a minimum of defects.
