Abstract
Laurel Materials has developed CleanGraphene, a hemp-derived graphene material that serves as a sustainable and cost-effective alternative to traditional graphene, which is typically sourced from petroleum or coal. The conventional production of graphene is expensive, energy-intensive, and depends on critical graphite resources, many of which come from countries that are not friendly to the U.S. CleanGraphene addresses these challenges by using industrial hemp as an inexpensive source of dicarboxylic acid, which reacts with carbon in water to produce graphene in an environmentally friendly and scalable manner. To assess its quality, CleanGraphene is being characterized using various techniques: X-ray Diffraction (XRD) for graphitic structure, Transmission Electron Microscopy (TEM) for platelet morphology and uniformity, Raman Spectroscopy for stacking order and sp² domain size, Thermogravimetric Analysis (TGA) for defect assessment, and X-ray Photoelectron Spectroscopy (XPS) for elemental composition. Additionally, tests are being conducted on its electrical and thermal conductivity to evaluate its suitability for different applications. Preliminary results indicate that CleanGraphene exhibits multilayer graphene characteristics that are comparable to or exceed those of traditional graphene materials. Potential applications for CleanGraphene include thermal interface materials for dissipating heat from electronic components, supercapacitor electrodes, and composite additives to enhance mechanical properties. By providing a high-quality, renewable alternative to conventional graphene, CleanGraphene could improve material performance while reducing environmental impact. This work aims to establish CleanGraphene as a viable alternative in industries that require high-performance carbon nanomaterials, thereby helping innovation in sustainable material development.
Importance
Graphene plays a crucial role in the development of next-generation electronics and energy storage solutions, yet existing production methods are costly and environmentally damaging, with a heavy reliance on imported graphite. CleanGraphene, derived from industrial hemp, presents a renewable and cost-effective alternative, significantly lowering production costs and reducing dependence on nonrenewable carbon sources. Preliminary findings indicate that CleanGraphene exhibits high electrical and thermal conductivity, making it ideal for applications such as supercapacitors and composite materials. By establishing a domestic source of graphene, this innovation enhances supply chains, promotes sustainable manufacturing practices, and lessens environmental impacts. CleanGraphene has the potential to increase the creation of more efficient materials, generate jobs, and position Pennsylvania as a leader in advanced and sustainable manufacturing.
