Dear Researchers,
Since CNT is not soluble in standard solvents like DI water, ethanol etc, how do I make a doping/composite of CNT and metal oxide. Your suggestions will be highly appreciated. The facilities in my lab are standard chemical synthesis and hydrothermal reactors.
Thanks and regards
Dear Sandip, You can go for acid functionalisation in the first then it will be easier to disperse CNTs in polar solvents. You can also try to use isopropanol as solvent, partially CNTs will get dispersed without any acid treatment.
Dear Sandip,
CNTs functionalization can be made through two major routs, namely covalent or non-covalent faunctionalization steps.
At first you must decide which protocol is suitable for you and then the other steps will be more clear. As Naresh answered above you can go to the acid-treatment protocols to obtain surface OH and COOH groups for further attachment of many molecules and also your metals. I think this method is more versatile for you however it depends on your final aim of project.
In the other method you might want to firstly disperse your CNTs by various polymers in the non-covalent route and then dopped your metals again through non-covalently interactions by means of many methods.
Also you might find these two papers useful as an examples of the two mentioned methods.
