基于富勒烯的棉织物离子传感器及其潜在应用

Cotton Fabric Ion Sensor Based on Fullerene and Its Potential Applications

将氧化石墨烯(GO)溶胶和富勒烯(C_(60))混合涂层整理到纯棉织物上制备柔性还原氧化石墨烯/富勒烯棉织物离子传感器(RGO/C_(60)-CF)。大量富勒烯球体可被嵌入到石墨烯片中,由于其缺电子特性,可对不同半径大小的阴离子或阳离子表现出不同的偶极—偶极相互作用,使得改性织物对不同的离子具有响应能力,即离子半径越大,改性织物的电阻率越大。该纺织基离子传感器还表现出对不同类型汗液的传感特性,这为其作为离子传感器的应用提供了依据。

A flexible reduced graphene oxide/fullerene cotton fabric ion sensor(RGO/C_(60)-CF)wasprepared by coating the cotton fabric with graphene oxide(GO)sol and fullerene(C_(60)).Large amounts of zero-dimension of fullerene spheres were embedded into RGO sheets,and they could exhibit different dipole-dipoleinteractions on various cations or anions with different sizes due to their electron deficiency characteristics,whichmade the modified fabrics show responsiveness to different ions.That is,the larger the ion radius was,the greaterthe resistivity of the modified fabrics was.The textile-based ion sensor also exhibited sensing characteristics fordifferent types of sweat,which provided a basis for its applications as an ion sensor.
