Abstract Carbons with sp2 and sp3 bonding exhibit entirely different envelope of properties. Here, we propose to fabricate and test (for mechanical properties) carbon nanocomposites by combining the two bonding. Recent advances in chemical vapor deposition of nanotubes and nanocrystalline diamond present a possible synergistic approach to synthesizing dense nanocomposite material with aligned and uniformly spaced nanotubes. CVD will be used to synthesize nanotubes oriented vertically to patterned substrates and by controlling the chemistry of plasma nanocrystalline diamond will be deposited on these. In addition, modeling of carbon nanotube-diamond hybrid microstructures will be done to understand mechanical properties and interfacial behavior.

摘要 具有sp2和sp3键的碳表现出完全不同的性质。在这里，我们建议制造和测试（机械性能）碳纳米复合材料相结合的两个键合。纳米管和纳米金刚石的化学气相沉积的最新进展提出了一种可能的协同方法来合成具有对齐和均匀间隔的纳米管的致密纳米复合材料。CVD将用于合成垂直于图案化衬底的纳米管，并通过控制等离子体的化学性质，将纳米金刚石沉积在这些纳米管上。此外，碳纳米管-金刚石混合微结构的建模将被完成，以了解机械性能和界面行为。
