Facile preparation and characterization of fibrous carbon nanomaterial from waste polyethylene terephthalate.

ABSTRACT

Efficient reduction of environmental pollution caused by waste polyethylene terephthalate (PET) and production of carbon nanomaterials are desirable for nanotechnology, printable electronics, composites and environment protection. Here we report a simple top-down micro/nano-fabrication process to prepare fibrous carbon nanomaterial from waste PET bottles. This process is highly efficient, facile, and catalyst-free in preparing fibrous carbon nanomaterial with promising hydrophobic and electrical properties. The fibrous carbon nanomaterial can be used both in the form of sheet or powder, and it supplies a versatile surface for preparing novel carbon-based composites with significant optical properties and conductivity. The prepared carbon nanomaterial from waste PET has also been used in fabricating strain sensor with good durability.
