FeCo@N-Doped Nanoparticles Encapsulated in Polyacrylamide-Derived Carbon Nanocages as a Functional Filler for Polyethylene System

In this work, using the advantages of Fe and Co nitrates acting as nucleation sites, we polymerized acrylamide (AAm) complexes using frontal polymerization to obtain FeCo alloy/N-doped carbon composites by converting its original precursor. The results of PAAm coating were found to be extremely useful in suppressing the collapse of the FeCo microstructure during pyrolysis, resulting in a unique hierarchical FeCo@C-N core-shell nanoparticle architecture encapsulated in PAAm-derived carbon nanocages. The thermal, mechanical and magnetic properties of the resulting FeCo/C-N filling polyethylene system have been investigated and presented.
