Fibers with Polyisoprenes from Jackfruit Latex (Artocarpus heterophyllus L.) by Electrohydrodynamic Processes: Fabrication and Characterization
This investigation aims to evaluate the feasibility of polyisoprenes from jackfruit latex (pure or combined with PEO or pullulan) to form fibers by electrospinning process. The pH, conductivity, and surface tension of the polyisoprene concentrate (PC) solutions and dispersions are evaluated. The ele...

| Sumario: | This investigation aims to evaluate the feasibility of polyisoprenes from jackfruit latex (pure or combined with PEO or pullulan) to form fibers by electrospinning process. The pH, conductivity, and surface tension of the polyisoprene concentrate (PC) solutions and dispersions are evaluated. The electrospun nanofibers are characterized by SEM, ATR-FTIR, thermal analysis, solubility, and water vapor transmission rate (WVTR). According to the physicochemical characteristics, the solutions are suitable for electrospinning. Fibers by electrospinning are obtained from all solutions (PEO/Pullulan + 0.2, 0.5, or 1% PC). ATR-FTIR spectrum of the nanofibers presents no differences with the presence of PC, suggesting that the interactions between the polymers are not covalent, which facilitates PC release. Nanofibers present homogeneous and continuous morphology, with diameters ranging from 200-400 nm with pullulan and 100-300 nm with PEO. Nanofibers show no statistical difference in the solubility parameter and present low WVTR values. Thermal analysis shows compatibility between polymers and the increase of thermal stability of PC when mixed with pullulan or PEO. Therefore, the PC-based nanofibers could be used for the encapsulation of bioactive molecules or in the development of dermal products based on the biological activities that have been attributed to polyisoprenes. |
