从CVD石墨烯发现到商业化

成立于2015年,石墨烯将军认为,一旦使高质量,廉价的CVD石墨烯膜的大规模生产成为可能,那么自然而然地,工业世界将积极地接触该公司,以解决各种基于CVD石墨烯的应用程序。

但是,当发现这种方法时 - 在2021年委托专有CVD生产系统 - 需求不如预期的那么大。

尽管许多财富500强公司(以及许多较小的公司)与一般石墨烯接触,但很快就意识到,与对需求的需求相关的微妙之处很少CVD石墨烯被考虑。

When reading about graphene’s potential and its exceptional properties, a few simple questions come to mind:

  • If claims regarding graphene are true, why are more companies not adopting it?
  • What stopped graphene from becoming the disruptive material that it was thought to be?

In recent years, General Graphene has met and worked with a significant number of corporate leaders across an extensive range of industries. This has provoked a better understanding of graphene.

While the general interest in graphene has been consistent, risk aversion is generally greater. The position many companies take up when it comes to graphene could be summarized as follows:

  • 只要比赛无法获得石墨烯,他们就可以接受相同的命运。
  • 克服石墨烯大规模生产的挑战是其他人要解决的问题。

但是,缩放此类障碍的能力突然意味着石墨烯具有截然不同的光环。

商业化CVD石墨烯的挑战和风险

There are many risks – technical, financial and market-oriented – that make the introduction of CVD graphene to any given market an intimidating challenge. Like all new materials, the areas that remain unknown are many and as such, unsurprisingly, adopting graphene is painfully slow.

尽管石墨烯提供了潜在的革命性发展,但大多数行业在首先行动时仍然保守,而无需完全了解综合过程和所涉及的成本。

当然,这是一个合理且可预测的位置,但是与引入石墨烯相关的极慢是对一般石墨烯仍然是一个重大挑战。因此,就像首先开发其专有方法的挑战一样,普通石墨烯致力于应对石墨烯摄取的惯性。

Since 90% of the companies that General Graphene encounters have never even heard of graphene, education is the first step towards commercialization.

Of the 10% who are aware of graphene, 90% believe graphene is just a black powder – and they are absolutely right. Graphene oxide (GO) is the better-known and more common type of graphene, although it barely qualifies as graphene according to the ISO’s technical definition of graphene (less than ten layers).

相比之下,单层CVD石墨烯不是粉末,并且确实符合ISO标准。它是碳原子的连续,实际上透明,不重的薄膜。

尽管这些材料本质上是截然亚博网站下载不同的,但“石墨烯”一词在工业背景下互换应用。因此,在大多数情况下,将石墨烯引入新市场时,众所周知的“地面零”的位置代表了起点。

一般石墨烯和应用程序开发的复杂性

鲜明的现实是,对于大多数石墨烯的存在中,对于许多不同的应用,CVD石墨烯都缺乏有意义的生产和测试。关于石墨烯的期望与石墨烯周围产生的炒作更一致,而不是现实。

This was a hard lesson to learn, but General Graphene is now infinitely better off for the experience.

In the coming months, General Graphene will determine exactly what the appetite will be for graphene on a global, industrial scale once they have discovered the company’s low-cost mass-production skills (The company has been intentionally ‘under the radar’ while developing its CVD graphene manufacturing technology).

但是,不管食欲是什么,基于石墨烯的应用程序开发的现实是它并不微不足道。

最初,具有非常具体应用的行业是针对目标的 - 基于同行评审的科学期刊的公开发现,称赞为特定应用提供的特殊属性和优势石墨烯。

但是,发现实验室结果不容易转化为现实世界的结果。石墨烯是一种令人难以置信的材料,但是长期以来的炒作可能会产生误导,这表现出了不切实际的期望,有时是不可能满足的。

如果将石墨烯的潜力和性能结果适当地纳入特定应用程序,则可以非常明显。但是,确切地确定如何将石墨烯纳入应用程序并不是自动过程,并且大多数行业仅限于使用原子级材料的经验。亚博网站下载

对于长期以来的等待应用程序,对于石墨烯来说可能还为时过早,但是对于其他几个石墨烯来说,已经出现了近期商业化的途径。在实现基于石墨烯的应用程序方面,成本是最大的障碍,因此一般石墨烯已大大降低或消除了其重要性。

The challenges are now more practical in nature: how can graphene be incorporated into existing production processes?

因此,石墨烯将集中在准备并愿意使用的行业中的应用程序上CVD石墨烯其中可以管理与现有生产过程相关的集成困难。

示例包括直接在应用程序中常用的金属底物上生长石墨烯的应用,以及在任何其他材料中无法获得石墨烯特征(例如原子薄度和/或灵敏度)的应用。亚博网站下载

Nondisclosure agreements (NDAs) prevent the full disclosure of current application development partners, but General Graphene is pursuing a significant number of projects in energy storage, consumer electronics, automotive, semiconductor, sensor, healthcare and defense sectors.

Identifying Graphene Applications: A Needle in a Haystack or a Needle in a Stack of Needles?

The successful development and commissioning of General Graphene’s GG 3.0 pilot production line has led to the capability to manufacture CVD graphene films at an exceptional scale and cost.

Each graphene-based application requires customization to its technical and/or performance needs (i.e., not all graphene is created equally). TheGG 3.0系统促进针对特定应用的石墨烯的微调。单层石墨烯可以以大型薄膜的形式产生,也可以滚动到300毫米宽的长度。

However, General Graphene’s technology truly represents the capability to ultimately engage in cost-effective testing, R&D and implementation across an extensive range of applications.

一般石墨烯不是只有一部单件小马,它仅集中在基于石墨烯的单个或细长的应用程序上。石墨烯非常通用,目的仍然可以释放出商业化道路上的多功能性。

General Graphene cannot say what the best – or even the first – large-scale graphene-based application will be, but it is confident that this is closer to being realized than the scientific and industrial world first thought.

General石墨烯的产品将是此类应用程序的一种促成技术,但是该应用程序本身不仅需要石墨烯生产。诸如此类的机会是没有限制的,因为基于石墨烯的应用程序开发只需要在一堆针中找到针,而不是在干草堆中找到针头。
