Heat radiation sheet and method of manufacturing same

A method of manufacturing a heat radiation sheet comprising the steps of:

• electrospinning a first spinning solution comprising an adhesive, first heat conductive particles, and a first solvent to form an adhesive layer in a form of a web having a plurality of pores;
• mixing second heat conductive particles and a second solvent to obtain a spraying solution;
• electrospraying the spraying solution onto the adhesive layer to disperse the second heat conductive particles on the adhesive layer;
• mixing a polymer material, a third solvent, and third heat conductive particles to obtain a second spinning solution;
• and
• electrospinning the second spinning solution onto the adhesive layer and the dispersed second heat conductive particles to form a heat radiation layer in a form of a web on the adhesive layer with the second heat conductive particles dispersed between the adhesive layer and the heat radiation layer.
