In this thesis, fabrication of highly thermal conductive and optically transparent film made of hexagonal boron nitride and transfer printing technique is demonstrated. To fabricate BN transfer printed film, bulk particle is exfoliated and edge functionalized by high energy ball milling and making a BN nanosheet dispersion. Through vacuum filtration with PTFE membrane, BN nanosheets are stacked and anisotropically aligned through membrane surface. BN nanosheet film than directly transferred to substrate, derived by solvent evaporation induced interface merging. As a result, defectless, smooth and uniform thickness of BN film is successfully transfer printed on various substrate including PET, Cu, glass vial, etc. The printed BN film is easy to adjust thickness and surpass optical transparency over 90%, and shows in-plane thermal conductivity over 20W/mK.
