用程序升温脱附（TPD）技术测定了多环芳烃CnHm（22 ≤ n ≤ 60）与高取向热解石墨的结合能。这些能量然后被用于通过Björk等人提出的精确外推法来估计分散石墨层间的内聚力。这产生了每个碳原子的内聚力能量为44.0 ± 3.8 meV。我们讨论了一些限制的TPD为基础的方法和对比我们的值与以前的测定层间结合能的石墨。
Temperature Programmed Desorption (TPD) spectroscopy was used to determine the binding energies of polycyclic aromatic hydrocarbons C n H m (22 ≤ n ≤ 60) with highly oriented pyrolytic graphite. These energies were then used to estimate the dispersive graphite interlayer cohesion by means of a refined extrapolation method proposed by Björk et al. This yields a cohesion energy of 44.0 ± 3.8 meV per carbon atom. We discuss some limits of the TPD-based approach and contrast our values with previous determinations of the interlayer cohesion energy of graphite.
