제목 Humidity-dependent Electrical Conductance of Carbon/Polymer Composite Micro-Fibers
초록 Electrically conducting composites based on carbon nanomaterials, such as graphene and carbon nanotube, are under consideration for numerous applications, such as electronics, energy devices, and sensors. Here, I discuss dependence of electrical conductance of a carbon/agarose-based composite microfiber on environmental humidity. A simple and general process for fabrication of the composite microfiber has been developed, based on size reduction during dehydration of extruded composite hydrogel filaments. The resulting composite microfiber is robust and conducting enough for the fabrication of fiber-type microdevices. Its humidity-dependent conductance enables the composite fiber to be used as a humidity sensor with good sensitivity and fast response time. Interestingly, the dependency of electrical conductance of a composite fiber with the conducting nanofillers on humidity is significantly affected by filler content, which has been systematically investigated.
