Utilization of the material-specific peptide-substrate interactions of M13 virus broadens colloidal stability window of graphene. The homogeneous distribution of graphene is maintained in weak acids and increased ionic strengths by complexing with virus. This graphene/virus conducting template is utilized in the synthesis of energy-storage materials to increase the conductivity of the composite electrode. Successful formation of the hybrid biological template is demonstrated by the mineralization of bismuth oxyfluoride as a cathode material for lithium-ion batteries, with increased loading and improved electronic conductivity.
M13 病毒的特定肽底物相互作用的利用拓宽了石墨烯的胶体稳定窗口。通过与病毒复合，石墨烯在弱酸和增加的离子强度下保持均匀分布。这种石墨烯/病毒导电模板用于储能材料的合成，以提高复合电极的导电性。通过将氟化氧化铋作为锂离子电池的阴极材料进行矿化，成功地形成了混合生物模板，从而提高了负载量和电子电导率。
