2D-PRINTABLE milestone achieved on materials functionalization!
We are happy to share that our partner from TUD completed another 2D-PRINTABLE milestone: “Proof of concept demonstration of tunable degrees of functionalization of 1–25% on TMDs as model substance”. The milestone relates to the successful functionalization of liquid and chemically exfoliated 2D materials using transition metal dichalcogenides (TMDs) as a model substance. An essential aspect of the 2D-PRINTABLE project is to exploit the potential of chemical modification to enhance nanosheet properties relevant to Printed Electronic applications. This is achieved by i) tailoring the processability and solvent choice through modification of the surface chemistry, ii) fine-tuning nanosheet properties (e.g., doping levels, band gaps, photoluminescence), and iii) developing the chemistry to achieve chemical coupling of nanosheets at edges and basal planes to produce flake-level homostructures and heterostructures. TUD has demonstrated the tunable functionalization of MoS₂, achieving a range of 2-40% using electrophilic radical addition reactions. This advancement marks a crucial step forward in the development of versatile and high-performance 2D materials.
