程序升温脱附实验表明，丙酮化学吸附在纳米管上，而物理吸附发生在石墨上。计算的高结合能的化学吸附使用混合量子力学和半经验计算与实验热脱附数据吻合良好。丙酮和纳米管表面之间的强化学相互作用被建立为是由于曲率和拓扑缺陷的影响。
Temperature-programmed desorption experiments show that acetone chemisorbs on nanotubes while physisorption occurs on graphite. Computed high binding energies for chemisorption using hybrid quantum mechanical and semiempirical calculations are in good agreement with the experimental thermal desorption data. The strong chemical interactions between acetone and the nanotube surface are established as being due to the effects of curvature and topological defects.
