The carbon nanotubes (CNTs) play an important role in nanotechnology research today as they have the potential to be used in several areas. Environmental protection is highly discussed nowadays, which is why it is necessary to be able to produce CNT forests with less energy investment and simply, for these reasons we used the dip-coating layer construction method, which is a simple process. We also would like to simplify the production of CNT forests by changing several parameters used in the syntheses (concentration of ink, catalyst ratios, temperature, the effect of heat-treatment, hydrogen, and water vapor, reaction time, carbon source). For these reasons, this research uses a dip-coating method to form a catalyst layer on the surface of the substrate, as well as to investigate various parameters to produce CNT forests directly on the titanium substrate, as it is important today to use a conductive substrate.

碳纳米管（CNT）在当今的纳米技术研究中起着重要作用，因为它们有可能在多个领域中使用。如今，环境保护已受到广泛讨论，这就是为什么必须能够以较少的能源投资生产CNT森林的原因，并且由于这些原因，我们简单地使用了浸涂层构建方法。我们还想通过更改合成中使用的几个参数（油墨浓度，催化剂比例，温度，热处理效果，氢气和水蒸气，反应时间，碳源）来简化CNT林的生产。由于这些原因，这项研究使用浸涂法在基材表面上形成催化剂层，
