Liu, Xianyuan published the artcileThermally conductive and electrically insulating alumina-coated graphite/phthalonitrile composites with thermal stabilities, Quality Control of 91-15-6, the main research area is alumina coated graphite phthalonitrile composite elec insulating thermal stability.
Alumina-coated graphite (Al2O3@graphite) core-shell particles were firstly synthesized by a liquid-phase chem. precipitation with the aid of sodium dodecyl sulfonate (SDS) surfactant using an inorganic precursor, then to fabricate thermally conductive and elec. insulating phthalonitrile composites by a hot-compression method. The obtained composite with 40 wt% Al2O3@graphite exhibited a thermal conductivity of 1.409 W/mK, 6.6 times that of pristine phthalonitrile matrix (0.214 W/mK). And the composites still retained elec. insulation below 20 wt% Al2O3@graphite content. Moreover, excellent thermal stabilities had been observed, compared with the glass transition temperature of pristine phthalonitriles (460°C), the glass transition temperature of the composites decreased slightly but still high. Addnl., at 20 wt% content, the weight loss temperature (T5 and T10) and the char yield at 1000°C (Yc1000) were 525°C, 589°C and 74.9% which was 8°C, 14°C and 3.1% higher than that of pristine phthalonitriles, resp., which holds potential for use in the high temperature thermal management.
Composites Science and Technology published new progress about Decomposition. 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Quality Control of 91-15-6.
