1997年11月1日 · In order to determine the burnt-out condition of polyvinyl butyral as a binder in the fuel cell, thermal gravimetric analysis, gas chromatography and gas chromatography/mass spectrometry are used to analyse decomposed products during the thermal decomposition process in the matrix-green sheet and electrolyte-green sheet.

2018年2月1日 · Graphene nanoplates (GN) were added to modify thermal conductivity of PVB. Thermal conductivity meter (TCM) and thermo-gravimetric analyzer (TGA) were used to investigate thermal properties of the composites like thermal conductivity and …

2024年2月1日 · Thermogravimetric analysis (TGA) was employed to evaluate the thermal stability of Polyvinyl butyral (PVB) polymer films doped with different concentrations of magnesium chloride hexahydrate (MgCl 2 6H 2 O). This analysis provided valuable information about the material’s decomposition behavior under heating, enabling prediction of its long ...

2023年12月16日 · To determine the thermal response of the PVB, thermogravimetric analysis (TGA) was carried out in an air atmosphere at a heating rate of 10 K/min in a temperature range between 295 and 873 K. The viscoelastic response of the PVB was analyzed by dynamic mechanical analysis (DMA) using a Perkin Elmer DMA8000 (Waltham, MA, USA), in …

2000年8月1日 · The pyrolysis of polyvinyl butyral (PVB) binder and other organic additives in thermoelectric green tapes, are analysed through differential thermal analysis (DTA), thermogravimetric analysis...

The TGA analysis of the PVB displayed in Fig. 5a II depicted the stability of the matrix, up to a temperature of ~300 ºC. Beyond this temperature, a steep loss in the mass occurred, related to...

2018年2月1日 · The thermal stability of the PVB and its composites was analyzed by a thermogravimetric analyzer (Pyris 1 TGA, Perkin–Elmer) from room temperature to 700 °C with a linear heating rate of 20 °C/min under a constant stream of nitrogen.
