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.

主权项

1. A process for producing activated polymeric structures, comprising the following steps:
(i) preparing a polymeric composition comprising a fluid medium and at least one component in the fluid medium, wherein the polymeric composition is a solution or an emulsion or a suspension or a dispersion, (ii) ejecting the polymeric composition through an ejector nozzle, aided by an electric field, and (iii) depositing on a liquid surface the polymeric composition ejected through the ejector nozzle, wherein the liquid surface is: (a) contained in a collector; (b) electrically conductive; and (c) electrically connected to a voltage source to attract the polymeric composition ejected through the ejector nozzle so as to produce during the depositing step activated polymeric structures in the collector, which are particles and/or filaments having activated surfaces with binding capacities.
