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.
高效减少废聚对苯二甲酸乙二醇酯（PET）造成的环境污染，并生产碳纳米材料，这对纳米技术、可印刷电子、复合材料和环境保护而言都是理想的。在此，我们报告了一种从废 PET 瓶制备纤维状碳纳米材料的简单自上而下的微/纳制造工艺。这种工艺在制备具有良好疏水性和导电性的纤维状碳纳米材料方面具有高效、简便和无催化剂的特点。纤维状碳纳米材料既可以片状形式使用，也可以粉末形式使用，为制备具有显著光学性能和导电性的新型碳基复合材料提供了通用的表面。从废 PET 制备的碳纳米材料还用于制造具有良好耐久性的应变传感器。
