Different types of block copolymers as graphene dispersants in water and ethanol will be presented. We synthesized amphiphilic block copolymers (PSt/PVP-b-PEO) by using RAFT polymerization, and these were used as both intercalation agent and dispersant for commercially available graphene (M-25, XGScience). The graphene was dispersed in the presence of the copolymers in ethanol and water and their surface morphology and electrical conductivity were investigated by using SEM, AFM and 4-probe conductivity meter. PVP/PSt-b-PEO showed a good dispersibility compared to Pluronic surfactants (Grants: MOTIE 10044338, NRF 2014R1A1A4A01007436). |
