Abstract

Carbon nanotubes (CNTs) with diameters ranging from 40 to 100 nm have been synthesized by the solvothermal process using ethanol as a carbon source and LaNiO₃ as catalyst. The synthesized CNTs can be used for filaments in high-impact polystyrene (HIPS). HIPS/CNT nanocomposites have been prepared by the melt–intercalation process. Thermogravimetric analysis and differential scanning calorimetry indicate that the thermal stability of HIPS/CNT nanocomposites is better than that of HIPS. The thermal degradation mechanism was investigated by pyrolysis gas chromatography mass spectrometry.
