How can you be sure that your CNT is functionalized?

[cubicboy]

Hi everyone;

I know you can try to dissolve CNTs in ethanol or some solvent then wait. After a while if you can't see sediment in the bottle then there is no problem, your CNTs are succesfully functionalized.

So my first question is how long does it take to decide that it is functionalized.

And second one what is the reliability of this method? (I know there are other methods which are used to support the result such as FTIR spectra. But can we trust just this method without using another one?)

The last and important one is that Do I have to use specific solvent which is related to my functional groups on CNTs?

Thanks in advance. </code>The answer to your first question depends on the type of functionalization and the amount of CNTs in the solution. It can take anywhere from a few minutes to several hours.The reliability of this method depends on how well the functionalization was done and how closely the solvent matches the functional groups on the CNTs. Generally, if you use a solvent that closely matches the functional group you are trying to functionalize, then you should have a good chance of success.Yes, you should use a specific solvent that is closely related to the functional groups on your CNTs. This will increase the chances of a successful functionalization and ensure that the functionalization is uniform.
