title: A smart pH responsive graphene/polyacrylamide complex via noncovalent interaction.
abstract: We report that the graphene sheets can be stably dispersed in water by hydrophobic interaction with polyacrylamide. Most interestingly, the resultant graphene-polyacrylamide complexes show a reversible pH responsive property although polyacrylamide itself does not possess such characteristics. This method opens up novel opportunities for the potential applications of graphene in intelligent sensors, biology, medicine, nanoelectronics and other relevant areas.
