Because three-dimensional nanocarbons have high specific area, small amount of nanocarbons easily form a network between neighbors. However, curvy three-dimensional nanocarbon fillers are hard to be completely filled with polymers at the filler/polymer interfaces, resulting in the formation of micro/nano pores within the composite. Thus, excellent thermal property of nanocarbon fillers couldn’t manifest within the polymer composite. Herein, self-assembled monolayer (SAM) was introduced on the surface of three-dimensional nanocarbon fillers to enhance the wettability between nanocarbon fillers and epoxy matrix. Owing to the extremely thin thickness of the SAM, interfacial resistance between nanocarbon filler and epoxy matrix was minimized, and thermal conductivity of the epoxy/nanocarbon composite was efficiently enhanced up to 40 % compared to the reference. |
