Magnetocuring: Directed Energy Materials (DEM) for Advanced Manufacturing

This project centers on optimizing Curie nanoparticles (CNPs) for magnetocuring, a groundbreaking Directed Energy Materials (DEM) technique designed for advanced manufacturing. CNPs convert magnetic fields into controlled heat, enabling precise and energy-efficient curing of adhesive resins, which is essential for industries like automotive, aerospace, and electronics.

The project’s main objective is to enhance the Specific Absorption Rate (SAR) and optimize the Curie temperature (Tc) of CNPs. Improving SAR ensures that the nanoparticles generate heat efficiently when exposed to alternating magnetic fields. Tc optimization enables the particles to regulate their temperature, providing precision during the curing process. This is crucial for high-strength bonding and streamlined production.

In addition to optimizing thermal performance, the project emphasizes the surface functionalization of CNPs. By developing advanced core-shell structures and applying tailored coatings, the project aims to improve particle dispersion and stability within resin systems. This functionalization ensures compatibility between the nanoparticles and adhesive resins, maximizing the effectiveness of magnetocuring.

Magnetocuring offers a sustainable, energy-efficient alternative to traditional curing methods. The use of localized, non-contact heating reduces energy consumption and shortens curing times, aligning with green manufacturing principles. This innovation minimizes waste while providing a scalable solution for industries seeking efficient and eco-friendly production processes. Overall, the project aims to revolutionize adhesive bonding and advanced manufacturing, delivering a highly efficient, adaptable, and sustainable technology.

Key areas of research in this project include:

• Particle Synthesis & Design: Development of core-shell nanoparticles with optimized SAR and precise Tc control. This includes doping strategies to enhance magnetic properties and create more efficient thermal energy conversion under alternating magnetic fields.
