| Abstract Scope |
This paper investigates the application of electrophoretic deposition (EPD) for creating high-performance thermoplastic interfaces on carbon fibers using Polyetherimide (PEI) nanoparticles. The study focuses on the characterization of the chemical and electrophoretic properties of PEI nanoparticles in aqueous dispersion, and their deposition behavior via EPD. The size distribution of PEI nano-particles in water dispersion is analyzed using Dynamic Light Scattering, revealing pH-dependent changes in particle size and surface charge. X-ray Photoelectron Spectroscopy analysis confirmed the presence of oxygen-containing functional groups on the nanoparticles, crucial for enhancing their electrophoretic mobility and surface adhesion. EPD experiments demonstrate the deposition of PEI nanoparticles onto stainless steel substrates and carbon fiber tows, highlighting the controllability of coating thickness and uniformity with varying deposition times. A resistive Joule heating method is employed to fuse the deposited nano-particles into continuous thermoplastic interfacial layers on the carbon fibers. The results underscore the scalability of this approach for industrial applications such as aerospace and automotive sectors, offering potential benefits in automated tape placement and continuous fiber 3D printing. Future research directions include optimizing process parameters and further evaluating mechanical properties to fully exploit the potential of PEI nanoparticle-based interfaces compatible with high-performance thermoplastic composites in advanced manufacturing scenarios. |
