摘　　要：研究了添加纳米石墨烯、碳纳米管、纳米氧化铝、碳化硅4种导热助剂对薄片导热性能的影响。结果表明,添加纳米石墨烯的薄片导热性能最好。与未添加导热助剂的薄片相比,纳米石墨烯添加量为3.2%时,薄片导热系数增幅达95.39%。进一步研究了不同水分条件下,纳米石墨烯用量对薄片导热性能的影响。结果表明,薄片导热系数随纳米石墨烯用量的增加而提高。当纳米石墨烯添加量0.83%、水分13.67%时,薄片导热系数增幅达30%以上。The effect of adding four kinds of thermal conductivity agents,nanographene,carbon nanotube,nano alumina and silicon car-bide,on the thermal conductivity of the tobacco was investigated. The results showed that the tobacco with nanographene had the best ther-mal conductivity. Compared with tobacco without thermal conductivity agents,the thermal conductivity increased by 95. 39% when the con-tent of nanographene was 3. 2%. The effect of the nanographene content on the thermal conductivity of the tobacco under different water con-tent conditions was further studied. The results showed that the thermal conductivity of tobacco increased with the increase of the nanogra-phene content. When the nanographene content was 0. 83%,the water content of tobacco was 13. 67%,the thermal conductivity of tobaccoincreased more than 30%.
