| Resumo: | The present investigation is related to the synthesis of polymeric membranes with piezoelectric characteristics, using the vinylidene polyfluoride (PVDF) material, which is a thermoplastic semicrystalline polymer; the membranes will be made up of micro and nano piezoelectric fibers of this material, which were manufactured using the Electrospinning technique, the separation distance of 4.5 cm, 8.5 cm, 11.5 cm from the needle The hypodermic ones referring to the collecting cylinder were the one used to collect the samples. The hypothesis of manufacturing process parameters related to the diameter of the micro and nanofibers of the piezoelectric material PVDF with its rotational structure Beta (β) was tested. The following techniques were performed: XRD, where the dispersion of the samples were 18.3o, 19.9o, 20.6o, is related to the internal rotational structure α and β, for the SEM the approximate diameter of 100 to 250 nm was obtained of the micro and nano fibers of the PVDF, two protocols were applied to the FTIR for the analysis of the spectra, one of them with bibliographic reference and the other with the frequency changes shown with the baseline and modified the nano fibrous membranes of the PVDF , in Raman the spectrum from 800 to 840 cm-1 shows the changes in its internal rotational structure of the modified and unmodified PVDF by bibliographic reference is observed with a qualitative analysis. |
