Title:
CONDUCTIVE FIBER SEPARATION APPARATUS
Document Type and Number:
Japanese Patent JP3845341
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus which has a simple structure, is small-sized and sorts and separates conductive fibers from nonconductive fibers, in particular, an apparatus which separates conductive nanotubes from nonconductive nanotubes.
SOLUTION: An electrode array is disposed in a flow path on a substrate and the electrode array is covered with an insulation film from above. When the fiber suspended in insulative liquid is caused to flow in the flow path while applying an alternate voltage to an electrode, a current flows through the conductive fiber, charge is induced instantaneously and the conductive fiber is attached to the electrode by an electrostatic force. The current does not flow, on the other hand, through the insulative fiber, the sufficient charge is not induced to a semiconductor fiber during a period of the applied alternate current and, therefore, the semiconductor fiber is not attached to the electrode. In such a manner, only the conductive fibers can be sorted.
