Resumo(s):	Local ferroelectric and piezoelectric properties of triglycine sulfate TGS nanocrystals embedded into poly ethylene oxide PEO electrospun ﬁbers were examined by piezoresponse force microscopy PFM . Piezoresponse contrast was found to be strongly dependent on the position being much stronger at the ﬁber periphery. A model of the distribution of TGS crystals inside the core-shell PEO-TGS ﬁber structure was proposed. TGS nanocrystals were unevenly distributed along the ﬁber axis and tend to grow near the surface of the ﬁber. The volume fraction distribution of the TGS crystals extracted from PFM measurements is in a good agreement with the data obtained from the dielectric constant measurements.
