REDUCED GRAPHENE OXIDE ACHIEVED BY INTENSE PULSE LIGHT IRRADIATION FABRICATION METHOD FOR PREPARING THE SAME AND WEARABLE GAS SENSOR COMPRISING THE SAME

摘要

The present invention relates to a graphene oxide reduced by light sintering at the top of a transparent polyimide, a process for producing the same, and a gas sensor including the same. More particularly, the present invention relates to a method for producing a thermally stable and transparent polyimide film, which comprises applying a graphene oxide on top of the polyimide film, forming a graphene oxide through a light sintering process, The light sintering process is completed in a very short time, so that a sensor in which reduced graphene oxide is bound to the top of the transparent polyimide film without thermal damage to the polyimide substrate can be manufactured. The reduced graphene oxide precipitated in this way undergoes light sintering to form a reduced size of reduced graphene oxide as the plate structure is cleaved and fractured to form pores between graphene oxide layers, And has a structure in which In addition, the present invention is characterized in that stable bonding of the graphene oxide and the polyimide substrate is attained by the strong reduction of the light energy. Thus, the reduced graphene oxide bound to the upper end of the fabricated transparent polyimide can be applied to a real-time wearable expiration sensor and an excellent harmful environment sensor through effective surface gas reaction, smooth gas infiltration and diffusion.;
