Needleless electrospun nanofibers containing microcapsules: a methodology for self-supported microcontainers
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 6
Abstract
The present paper investigates the facile production of electrospun polyvinyl alcohol (PVA) nanofibers containing either micro-sized polymer or hybrid capsules, using a needleless electrospinning system. Oilcontaining microcapsules with diameters of around 3 or 10 µm, respectively, were produced via an oil-in-water miniemulsion and mixed with a PVA solution. Appropriate adjustment of electrospinning parameters enabled a controlled assembly of PVA nanofibers into a network containing microcapsules, without damaging their integrity. The PVA nanofibers have diameters in a range of 200-300 nm and showed good homogeneity. The introduction of microcapsules caused an increase in the PVA nanofiber diameters probably due to an increase in the solution viscosity. The production of such self-supported and loaded microcontainers could be of high interest for various applications.
