Abstract:
The present invention relates to a method to produce doped graphene using microwave. According to the present invention, graphene, of which 0.01-10 wt% of a heterogeneous element is doped, is obtained by making graphite and an organic compound dope react in the existence of a microwave for graphite intercalation, and by the organic compound inserted between the multi-layered graphite layers to peel the graphite to be of different graphene layers at the same time. Therefore, the method of the present invention can be useful in producing a graphene semiconductor, since graphene can easily be produced which has a much higher purity due to the suppressed usage of toxic chemicals such as hydrazine when compared to a conventional chemical peeling method, and a very simple and cheap process thereof can produce a doped graphene under suppression using a complex and expensive equipment such as a vacuum equipment when compared to a graphene synthesis method by a CVD method at the same time.

Abstract:
The present invention relates to an elastomer-conductive filler composite with improved dielectric properties by using a conductive filler dispersed by using an ionic liquid and a manufacturing method thereof. By increasing the dispersion effect of the conductive filler using an ionic liquid as a dispersant, high dielectric coefficient and low dielectric loss are provided without the loss of physical properties of the conductive filler. The used ionic liquid simplifies the process step, and the conductive filler with low concentration minimizes the degradation of physical properties.
