Versatile water soluble graphene nanoplatelets for water-based polymers

Water insoluble graphene nanoplatelets was converted to water soluble graphene nanoplatelets (GNPs) by a facile modification method. The water soluble GNPs easily dispersed in water-based polymers such as latex and polyvinyl alcohol with only mild agitation. The GNPs-fortified latex and GNPs-fortifi...
