| Abstract:The effect of adding four kinds of thermal conductivity agents， nanographene， carbon nanotube， nano alumina and silicon carbide， on the thermal conductivity of the tobacco was investigated. The results showed that the tobacco with nanographene had the best thermal conductivity. Compared with tobacco without thermal conductivity agents， the thermal conductivity increased by 95.39% when the content of nanographene was 3.2%. The effect of the nanographene content on the thermal conductivity of the tobacco under different water content conditions was further studied. The results showed that the thermal conductivity of tobacco increased with the increase of the nanographene content. When the nanographene content was 0.83%， the water content of tobacco was 13.67%， the thermal conductivity of tobacco increased more than 30%. |
