Study of Reduced Graphene Oxide Property and Application

Abstract

Graphene Oxide is a substance capable of working in a typical laboratory or indoor environment. Usage is also simple and also because of the toxic materials in contact is very easy to work. If the non-conductive nature of the process itself have only column characteristics or by laser energy reduction processes occurring in the applied part "Reduced Graphene Oxide" has electrical conductivity. While as the non-processed surface of non-conductive properties is manufactured in a form to enable this with the two characteristics simultaneously. The electrical resistance value varies according to the amount of energy input. That is the difference in electrical resistance occurs. When the process is repeated for the same position as the laser has a built-in property of the resistance value decreases. Because of this characteristic it has been utilized in the semiconductor and memory, which appears to be the next circuit making the composite itself. In this study, the trying to make the application of the application fields to see a change with the amount of laser energy thereto and refocus the electrical characteristics of rGO. rGO is utilized to expect sensor which using swell property in reduction processor and mixing nano particle. Particularly, recent rGO research is bio and blood base clinic (medical field) to target. This method is coping with the sensor using an expensive reactive substances that are produced by the will of the existing proteins and various enzymes to the sensor using the physical properties, the enzyme or the protein sensor a breakthrough resolved in a matter of persistent storage and expiration date. In fabricating the sensor, so that utilized rGO in glucose measurement is expected to be opened, the length of the large quantity of production at a lower price. These should be capable of quick and easy to manufacture device to mass production. In this study, we propose a method using direct laser scribe. Laser equipment is easy to manufacture and consists of a configuration using the industrial robot or other general-purpose motor. In addition, easily and expeditiously making processor can manufacture sensor with a laser scribe. There shall be no restrictions on the disposal or storage of materials. The storage and disposal easier and self-produced and mass production of the sensor should be presented several experimental and environmental conditions for access to the produce. This study presents a laser scriber capable of easily and quickly making how to create the rGO with the non-toxic GO. rGO sensor performance analysis that manufactured through laser fabrication process. These will be proposed the availability, future development direction and improvement of the glucose measurement. ⓒ 2016 DGIST
