Abstract
The present invention relates to a process for producing polymeric structures that have activated surfaces. The process proved to be simple, quick, with high production capacity and low operating costs. The process occurs by depositing a polymer solution, which is assisted by a high electric field, on a conductive liquid surface to produce particles and/or filaments that have an activated surface. More particularly, the process of the present invention has the ability to produce particles and/or filaments that have chemically activated surfaces, in a single process.
