Dual Functionalization of Hexagonal Boron Nitride Allotropes using Pyrene-tethered Poly(4-vinyl-pyridine) |
| 초록 |
For solution processability, the development of a stable dispersion of two-dimensional (2D) boron nitride (BN) has received significant attention for cutting-edge optic/electronic applications. Herein, we report an efficient method to disperse BN nanosheets (BNNSs) in polar solvents via dual non-covalent interactions using pyrene-tethered poly(4-vinylpyridine) (P4VP-Py). P4VP-Py enables bi-functionalization, resulting in highly stable BNNS dispersions in polar solvents. The blend of P4VP-Py-functionalized BNNS with the P4VP matrix resulted in increased thermal conductivity and dielectric constant combined with superior thermal stability by forming a compatible interface between the P4VP-Py matrix and the BNNS adjacent to the P4VP-Py. We demonstrated that dual non-covalent functionalization of BNNSs based on molecular design presents a strategy to achieve high dispersion of 2D materials into various media for the expansion of advanced optic/electronic applications using BNNSs. |
