Abstract EN
The chemical inertness and poor wetting properties of boron nitride nanotubes (BNNTs) hindered their applications.
In this work, BNNTs have been functionalized with aniline groups by reacting with diazonium salt and the graft content of aniline component was calculated as high as 71.4 wt.%.
The chemical structure, composition, and morphology of functionalized BNNTs were carefully characterized to illustrate the modification.
The anilinocarbocation generated by decomposition of diazonium salt reacted not only with NH2 sites, but also with B-OH sites on the surface of BNNTs.
Meanwhile, the reaction applied a hot strong acid environment, which would help to open parts of B-N bonds to produce more reactive sites and enrich the functional groups grafted on the surface of BNNTs.
Consequently, the functionalized BNNTs exhibited significantly improved dispersion stability in chloroform compared with pristine BNNTs.
Amino surface functionalization of BNNTs offered more possibilities for surface chemical design of boron nitride and its practical application.
