2017年11月27日 · PAN and PMMA solutions in DMSO and dilute solutions in DMF support CNT dispersion more than other combinations whereby the polymers significantly adsorb onto CNTs in DMSO solution. The observations by molecular simulations are consistent with available experimental data and solubility parameters and aid in the design of carbon nanofibers.

2010年10月1日 · This paper reviews the current understanding of CNTs and CNT/polymer nanocomposites with two particular topics: (i) the principles and techniques for CNT dispersion and functionalization and (ii) the effects of CNT dispersion and functionalization on the properties of CNT/polymer nanocomposites.

2022年11月15日 · This report compared the dispersion effect of salt dispersion by using NaClO and NaBr on a variety of carbon nanoparticles (graphene, CNT, and C 60). We compared its dispersion and mechanism with those using SDS, NMP, and a super-acid (MSA).

CNT is believed to solve the trade-off issue between permeability and selectivity, and also fouling problems in membrane filtration applications. Their fullerene form is a key point to provide a higher pore size on membrane surface as well as empty …

2015年2月24日 · I use 70% N-Methyl-2-Pyrrolidone (NMP) for dispersing CNT and sonicate for 1 to 2 hr. Then I centrifuge for 30 min @ 6000 rpm and take supernatant dispersed solution.

2019年1月2日 · Carbon nanotubes (CNTs) are a central part of advanced nanomaterials and are used in state-of-the-art technologies, based on their high tensile strength, excellent thermal transfer properties, low-band gaps and optimal chemical and physical stability.

2017年8月25日 · In this study, we dispersed CNTs in N-methyl-2-pyrrolidone (NMP), together with the dispersing agent modified nitrile butadiene rubber (mNBR), at fixed CNT concentrations using a combination of shear mixing and ball-milling methods.

We consider the effects of salt (sodium iodide) on pristine carbon nanotube (CNT) dispersions in an organic solvent, N-methyl-2-pyrrolidone (NMP). We investigate the molecular-scale mechanisms of ion interactions with the nanotube surface and we show how the microscopic ion–surface interactions affect the st

2012年12月1日 · CNTs (such as n-methylpyrrolidone, NMP) are those with surface tensions close to that of graphene surfaces. The affinity between the solvent molecules and the graphene walls renders the...

2017年4月18日 · 本文综述了碳纳米管的各种分散方法,分析了碳纳米管的分散机理,提出了均匀分散碳纳米管要满足的必要条件:打散碳纳米管团聚体、剪断长碳纳米管、保持碳纳米管分散状态。 碳纳米管团聚体形态. 可以看到单根碳纳米管为纤维状一维纳米材料,长径比很大;同时碳纳米管交结纠缠在一起,形成很大的团聚体。 材料达到纳米尺度以后会表现出很多纳米尺寸效应,以零维的微观颗粒来讲,当颗粒尺寸达到纳米尺度以后,其团聚效应显著增加,团聚体内颗粒的相互吸引力也显著 …
