Facile Monomer Phase Exfoliation and Thin Film Processing of Layered Transition Metal Dichalcogenides: 2D Material Nanocomposites for High-Performance Optical Coatings
We demonstrate the facile exfoliation of transition metal dichalcogenides (TMDCs) directly in neat acrylate monomers resulting in readily processable stable colloidal dispersions─bypassing conventional methodologies that require process-limiting solvents and nanomaterial ligand functionalization. As such, we likewise demonstrate the controlled ease of fabricating polymer/TMDC nanocomposite thin films via free radical and anionic polymerization with minimal to no post-exfoliation processing. Our polymer/TMDC nanocomposite films offer tailored effective optical properties (i.e., effective refractive index, neff, and effective extinction coefficient, keff) simply by adjusting the exfoliated TMDC colloidal dispersion concentration prior to thin film fabrication. Our nanocomposite films yield appealingly large changes in effective optical constants of up to ∼Δ2.2 for neff and ∼Δ1.8 for keff (as compared to neat polymer), which contrast is necessary to develop application-relevant optical coating systems. The direct exfoliation of TMDCs in neat monomers and the ease of thin film nanocomposite processing present alternative approaches for high-performance optical coating development with utility in sensing, imaging, and energy harvesting.
