Key concepts
Scholarcy highlights
- Controlling the length of CNTs is important for their applications
- The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
- We have developed a versatile thin film microfluidic method, which is high in green chemistry metrics, for controlled disentangling and slicing both single-walled CNTs and multiwalled CNTs
- The method uses the mechanoenergy generated in a biphasic immiscible mixture of water and o-xylene in a titled vortex fluidic device operating at ambient temperature, without the need for using surfactants or other axillary reagents and without the need for applying external fields
- This simple method can achieve a yield of 93% under continuous flow conditions
