In this work we present the synthesis and characterization of polyethylene oxide (PEO) based
triglycine sulfate (NH2(CH2OOH)3H2S04, TGS) nanofibres obtained by electrospinning. The
fibres, with typical diameters of about 190–750 nm and above several hundred micrometres in
length, present the nanocrystals of TGS embedded in a polymer matrix. The obtained
nanofibres were characterized by FT-IR spectroscopy and the domain structure was examined
by piezoforce microscopy. Dielectric permittivity measurements on the TGS–PEO nanofibres
exhibit the characteristic ferroelectric–paraelectric phase transition at around 50 ºC.This work was financially supported by Fundacao para a Ciencia e Tecnologia (reference CIENCIA-2007 UMINHOCF-06). The authors would like to acknowledge Luis Vieira for help in FT-IR measurements
