Thermal conductivity measurements on PANI/SBA-15 and PPy/SBA-15
摘要
Abstract
Conductive polymers polyaniline（PANI） and polypyrrole（PPy） loaded mesoporous silica（SBA-15） composites are prepared and characterized.The one-dimensional reference bar method and the relevant devices to measure the thermal conductivity are introduced and established.The equivalent pore diameter is proposed to characterize the mesostructures of conductive polymers polyaniline（PANI） and polypyrrole（PPy） in PANI/SBA-15 and PPy/SBA-15 composites.The effects of the equivalent and the measurement pore diameters on thermal conductivities of PANI/SBA-15 and PPy/SBA-15 composites are analyzed.The result shows that thermal conductivities of PANI/SBA-15 and PPy/SBA-15 are higher than that of the substrate SBA-15;the thermal conductivity of PANI/SBA-15 is higher than that of PPy/SBA-15;loading of PANI and PPy in pores of PANI/SBA-15 and PPy/SBA-15 composites is more effective than loading outside of pores for improving the thermal conductivities of PANI/SBA-15 and PPy/SBA-15 composites.关键词
