METHOD AND APPARATUS FOR PRODUCING POLYMERIC STRUCTURES

摘要

The present invention relates to an apparatus and a method for producing polymeric structures such as microfibres, nanofibres and microbubbles. The method involves simultaneously subjecting a polymer solution to at least two of the following conditions: rotation, pressure and a voltage. The apparatus of the invention typically includes a cylindrical vessel having holes extending therethrough, and further comprises at least two of (i) rotation means, (ii) pressure exertion means and (iii) an electrical source. Advantageously, the method and apparatus of the invention allow for the production of high yields of polymeric structures at ambient temperature without a requirement for extrusion nozzles or complex spinnerets.
