Circular Carbon Nanotube Production for Advanced Structural Fiber Applications.

ABSTRACT: Plastic waste accumulation remains a global challenge, with only a small fraction currently being recycled. Upcycling postconsumer plastics into value-added materials offers a sustainable solution for waste reduction and advanced manufacturing. In this study, we demonstrate a cost-effective method for synthesizing multiwalled carbon nanotubes (MWCNTs) from postconsumer plastics via catalytic chemical vapor deposition. The waste-derived MWCNTs were incorporated into polyacrylonitrile (PAN) through wet spinning to fabricate high-performance composite fibers. Compared to conventional PAN-based fibers that use commercially sourced CNTs, which often contain residual catalysts that weaken performance, the synthesized MWCNTs exhibit lower metal content and enhanced crystallinity (66%), reducing d
