Integrating graphene with other kinds of biochemical molecules is an effective way to improve the properties of graphene film. Proteins are promising candidates for graphene hybridization. We create an effective method to prepare multifunctional graphene hybrid film by incorporation of antibacterial protamine. Protamine could be stably adsorbed on the surface of GO as both a reductant and an antibiotic to realize antimicrobial protamine/RGO conjugates. The presence of decorated protein layers makes it possible to adjust the physical performance of the composite. The obtained hybrid papers show improved hydrophilic property of reduced GO paper. These freestanding papers have a reversible humidity response shape-memory effect and great antibacterial property. The facile strategy possesses a promising way to develop multifunctional antibacterial materials.

将石墨烯与其他种类的生化分子结合是提高石墨烯薄膜性能的有效途径。蛋白质是石墨烯杂交的有希望的候选者。我们创造了一种通过掺入抗菌鱼精蛋白来制备多功能石墨烯混合膜的有效方法。鱼精蛋白可以作为还原剂和抗生素稳定吸附在 GO 表面，以实现抗菌鱼精蛋白/RGO 偶联物。装饰蛋白层的存在使得可以调整复合材料的物理性能。获得的混合纸显示出还原 GO 纸的亲水性得到改善。这些独立纸具有可逆的湿度响应形状记忆效应和出色的抗菌性能。
