NOVELTY - Preparation of blend involves dissolving 0.1M cobaltous nitrate hexahydrate in a deionized water to make a homogeneous solution, adding 1 wt.% graphene oxide to the solution to form a mixed solution, adjusting the pH of the mixed solution to 10, stirring the pH adjusted mixed solution at 60 degrees C overnight, washing the stirred solution with ethanol and air drying to obtain a cobalt (II,III) oxide-graphene oxide nanohybrid, and blending 70 wt.% carbon nanotube with 30 wt.% cobalt (II,III) oxide-graphene oxide nanohybrid. USE - Preparation of blend for filling casing for thermoelectric cell used in instrumentation for measurement of temperature gradient in bio-medical applications. ADVANTAGE - The method enables simple and economical preparation of blend for filling casing for thermoelectric cell having high efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of rod-shaped flexible elastic casing.
