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 C.
