PROCESS FOR PRODUCING POLYMERIC STRUCTURES THAT HAVE ACTIVATED SURFACES AND ACTIVATED POLYMERIC STRUCTURES |
| 摘要 |
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. |

1. Process for producing activated polymeric structures, characterized by comprising the following steps:
(i) prepare a polymeric solution or emulsion or suspension or dispersion, comprising at least one solute and at least one solvent, and (ii) eject the polymeric solution or emulsion or suspension or dispersion through an ejector nozzle, aided by an electric field, on a liquid surface. |
