Regardless of their applications, polymers are still considered mechanically weak and functionally insufficient for certain demanding coating adhesive uses. To address those issues, nanomaterials have been extensively studied as reinforcing fillers, which proven to effectively promote the performance polymer coatings/adhesives. However, conventional nanofillers expensive non-biodegradable. Meanwhile, cellulose (CNMs), a class produced from biomass feedstocks, can circumvent drawbacks...
Carbon fiber filled acrylonitrile butadiene styrene (CF-ABS) is an emerging 3-D printable, recyclable thermoplastic composite. A popular application for CF-ABS printed molds using large scale additive manufacturing (AM) processes produced a variety of composites end-users. Other applications have not been fully realized as currently has higher cost than other polymer composite feedstocks. The could be greatly reduced if recycled material was accepted and utilized industrially, which would...
Wind energy is widely deployed and will likely grow in service of reducing the world's dependency on fossil fuels. The first generation wind turbines are now coming to end their lives, there limited options for reuse or recycling composite materials they made of. Current literature has verified that no existing pathway (i.e., mechanical, chemical, thermal methods recovery, etc.) end-of-life blades can meet cost parity with landfilling US. However, authors' knowledge study date uncovers...
ABSTRACT Epoxy thermosets have revolutionized the coating, adhesive, and composite industries but chemicals from which they are synthesized significant effects on environment human health not only precure also after crosslinking has occurred. In this study, we propose tannic acid (TA) as an alternative epoxy hardening agent for commercially available resin, diglycidyl ether of bisphenol A (DGEBA). The resulting were characterized by Fourier transform infrared spectroscopy, optical...
Sustainable, non-halogenated flame retardants are desired for a variety of industry applications. Lignin, an industrially processed wood derivative, has been examined as potential sustainable retardant additive to polymer systems. Here, the lignin is phosphorylated using pyridine-catalysed esterification reaction with diphenyl phosphoryl chloride improve its char-forming abilities. The chemical modification was characterised by nuclear magnetic resonance spectroscopy and showed formation...
Abstract Most wind turbine blades reaching end-of-life are sent to landfill where embedded cost, energy, and materials lost. To avoid landfilling future blades, a broad range of recycling material recovery approaches have been proposed as solutions in the U.S., each with benefits, challenges, varying levels technical maturity. The include 1) cement co-processing, 2) mechanical recycling, 3) pyrolysis, 4) microwave pyrolysis 5) solvolysis. While these all capable recovering various forms for...
Abstract Over the past several years, wind energy industry has received scrutiny regarding turbine blade (WTB) recycling due to landfilling of WTBs caused by a lack industrially viable solutions. The amount that will need be recycled is set increase in United States as deployment expected rapidly grow meet nation’s goals 2035. While significant progress been made worldwide, it still unclear which WTB solutions would most cost and effective within for existing fleet turbines. To guide...
Tannic acid (TA) is a bio-based high-molecular-weight organic molecule. Although biologically sourced, TA pollutant in industrial wastewater streams, and there desire to find applications which downcycle this Many flame retardants (FRs) used epoxy are synthesized from petroleum-based monomers. Various modifiers have been developed, but increasing the retardancy of system without trade-offs with other properties has proved challenging. In work, incorporated into thermoset. The molecular...
Abstract Engineering curricula have begun to provide opportunities for inclusive and diverse learning. The National Science Foundation (NSF) Integrative Graduate Education Research Traineeship (IGERT) Program: Global in Sustainable Electronics” is an example of one such initiative. program brought together s interdisciplinary group students study the environmental, economic, societal aspects global electronics lifecycle. IGERT was designed as a two-year training with two-week international...
