2019年9月1日 · This review summarizes progress on structural composites with carbon nanotube (CNT) fibres. It starts by analyzing their development towards a macroscopic ensemble of elongated and aligned crystalline domains, alongside the evolution of the structure of traditional high-performance fibres.

2023年3月1日 · CNT fibers (CNFs), as one-dimensional materials assembled by large amount of CNTs, possess promising mechanical properties and could potentially be used in many fields. However, due to the difference of fabrication methods, the twisting degree and length of CNTs in CNFs are distinct which is vital for mechanical design and optimization of super ...

2022年8月17日 · Carbon nanotube fibers (CNTFs) have attracted extensive interest and are desirable building blocks for advanced functional fibers because of their extraordinary tensile strength, high flexibility, light weight, high specific surface areas, excellent electrical properties, and high thermal conductivity.

- CNT fibres can be best described as molecular solids, or graphitic systems with Decoupled crystallinity parallel/perpendicular to basal plane. - Their tensile properties can be described by the USM and a Weibull distribution of stress distribution through the cross section, with alignment dominating over composition

2021年1月19日 · Carbon nanotube (CNT) fiber (CNTF), which is a collection of many CNTs aligned along the fiber axis, has attracted significant attention as a next-generation material with excellent properties. CNTF is a macroscopic material that potentially resembles the intrinsic properties of CNTs (high strength, conductivity, flexibility, etc.) that ...

2015年11月18日 · In the presence of macroscopic fibres of carbon nanotubes (CNT), various semicrystalline polymers are shown to present accelerated crystallisation through the formation of a transcrystalline...

2018年5月14日 · Fabricating CNT fibres with strength reaching that of a single CNT has been an enduring challenge. Here, we demonstrate the fabrication of CNT bundles (CNTBs) that are centimetres long with...

2021年7月1日 · For CNT fibres produced by direct spinning from floating catalyst chemical vapor deposition (FCCVD), a scaled-up method, the challenge is to simultaneously achieve high process conversion and high-performance properties.

2019年7月4日 · Here, we demonstrate the feasibility of a highly-efficient and potentially-continuous fiber-spinning method to produce high-performance carbon nanotube (CNT) fiber (CNTF). The processing time is...

2020年4月28日 · The fabrication of large unidirectional fabrics with similar properties as the fibres is presently a challenge, which CNT alignment remaining a key factor. A promising approach is to produce fabrics directly from aerogel filaments without having to …
