Abstract
Electrospinning is a technique that allows obtaining new fibrous structures from synthetic or natural polymers for the development of materials used in the pharmaceutical and biomedical industries, among others. However, the low production rate of electrospinning has limited its industrial application, forcing the development of new injectors that allow higher productivity. In this work, a coaxial injector was designed to develop products encapsulated in polymeric fibers. For the demonstration of the encapsulation of one fiber included in another, fluorescein was used as internal compound in a polyvinyl alcohol solution, and polyvinyl alcohol was used as external fiber. It was obtained that the encapsulation process is possible by using this coaxial injector.
