项目摘要

This Small Business Innovation Research (SBIR) Phase I project aims at developing a novel low-cost method for the preparation of Multi-Walled Carbon Nanotubes (MWCNT) for Field Emission Displays (FED) applications. Carbon nanotubes (CNTs) are characterized by high aspect ratio and small radius of curvature at their tips. This structural property, together with high electrical conduction, chemical inertness and mechanical strength makes them promising emitters for field emission flat panel displays. CNTs have been conventionally prepared by high-pressure, chemical-vapor-deposition processes, but these approaches have serious limitations owing to high cost of production. Recently suggested alternative methods of CNT preparation include plasma activation and catalytic growth, but they are limited by low yields or metal contaminations. In this Phase I effort, Materials Modification, Inc. proposes to synthesize carbon nanotubes from readily available raw materials by combining a pyrolysis and chemical process. The CNT thus produced will be chemically pure since no metal catalyst is used in the process and any side-products formed are in vapor state and will not contaminate it.Potential commercial applications include display aided flat bedded control panels, all types of touch screen facilities, flat panel monitors for both professional and entertainment displays, and naval and air surveillance systems.

这项小型企业创新研究（SBIR）I期项目旨在开发一种新型的低成本方法，用于制备用于现场排放显示（FED）应用的多壁碳纳米管（MWCNT）。碳纳米管（CNT）的特征是高纵横比和小曲率的小半径。这种结构特性以及高电导传导，化学惰性和机械强度使它们成为现场发射平板显示器的有前途的发射器。 CNT通常是通过高压，化学蒸气沉积过程制备的，但是由于生产成本高，这些方法具有严重的局限性。最近建议的CNT制备方法的替代方法包括血浆激活和催化生长，但受到低产量或金属污染的限制。在这一阶段，Materials修饰公司提议通过结合热解和化学过程来合成容易获得的原料的碳纳米管。因此，因此产生的CNT将是化学纯净的，因为该过程中没有使用金属催化剂，并且形成的任何副产品均处于蒸气状态，并且不会污染它。潜力的商业应用包括显示辅助的平坦床层控制面板，所有类型的触摸屏设施，专业和娱乐展示的平板监视器，以及海军和空中监视系统。
