更糟糕的则是它们本身强烈的各向异性 — — 这种材料拥有一个由大量互相弱连结的导电薄层所组成的准二维结构，因此虽然不断得到应用，对工业界来说也极富技术难度。
This is exacerbated by their strong anisotropy – the materials have a quasi-two-dimensional structure consisting of a weakly coupled stack of conducting sheets. As such, they are a challenge for industry, though applications are beginning to appear.
