Pyroelectric response of TGS-PEO composites

0-3 type composites of triglycine sulphate, with high molecular weight polyethylene oxide were prepared by hot-pressing. FT Raman spectroscopy was used to control the interaction of glycine ions with the polymer. Pyroelectric and electric response was studied for composite samples in the form of dia...

Description
Summary:0-3 type composites of triglycine sulphate, with high molecular weight polyethylene oxide were prepared by hot-pressing. FT Raman spectroscopy was used to control the interaction of glycine ions with the polymer. Pyroelectric and electric response was studied for composite samples in the form of diaphragm fixed on its perimeter and poled in low dc field (E p = 6MV/m). Pyroelectric response in the current mode of TGS/PEO composites decreases on increasing the light modulation frequency. Pyroelectric coefficient evaluated for TGS/PEO composites at 10 Hz amounts to ∼ 7.10 −5 C/m 2 K.
