dc.description.abstract | Poly(vinylidene fluoride) (PVDF) combined with cobalt ferrites particles (CFO) is one of the most common and effective polymeric magnetoelectric composites. Processing PVDF into its electroactive phase is a mandatory condition for featuring electroactive behavior and specific (post)processing may be needed to achieve this state. However, by processing at a temperature below 60 ºC, electroactive phase crystallization is favored. Besides, different experimental techniques are used to process various forms of PVDF-CFO nanocomposites structures being aware that high CFO dispersion must be achieved. Microfluidics offers the possibility of processing PVDF-CFO microspheres with high reproducibility, size tunability, and time and resources efficiency. Moreover, magnetoelectric microspheres are produced in a one-step approach. Thus, the present work describes the production of high content electroactive phase PVDF and PVDF-CFO microspheres using microfluidic technology. A flow-focusing polydimethylsiloxane (PDMS) device is fabricated based on a 3D printed polylactic acid (PLA) master. The device enables the production of spherical microspheres with mean diameters ranging from 80 and 330 µm depending on the continuous/discontinuous feeding ratio. The microspheres feature internal and external cavernous structures and good CFO distribution with an encapsulation efficacy of 80%. Moreover, the microspheres prove to be in the electroactive γ-phase with a mean content of 75%. Thus, the prepared microspheres show suitable characteristics as active materials for tissue regeneration strategies. | por |
