Photodegradation of dispersants in colloidal suspensions of pristine graphene.

Journal of colloid and interface science

Hansen MJ, Rountree KS, Irin F, Sweeney CB, Klaassen CD, Green MJ.

J Colloid Interface Sci. 2016 Mar 15;466:425-31. doi: 10.1016/j.jcis.2015.10.027. Epub 2015 Oct 22.

We demonstrate that UV degradation can remove polymeric dispersants from the surface of colloidal pristine graphene. In particular, we investigated the irradiation of polyvinylpyrrolidone (PVP)-dispersed graphene in water; this polymer has been established as a versatile nanosheet dispersant for...
