Carboxyl and polyamine groups functionalized polyacrylonitrile fibers for efficient recovery of copper ions from solution

Recycling and repurposing of waste carbon nanofiber polymers: a critical review

“…89 However, further research is needed to synthesize them using less toxic solvents or solvent-free methods and to explore the ability to produce nanofibers from mixed waste streams, ensuring the true scalability of this alternative recycling approach. 46,90…”
