Fig. 2: Customizable mTP process based on solubility parameters.

The Hansen solubility parameters of the interface components used in mTP (ligands, brush, carrier, support polymers, and solvents) are plotted alongside the intrinsic colors of the QDs: green for CdSe, red for InP, black for PbS, and white for ZnO. The volume ratios of PDMS/PS for the brush and of PS/PMMA for the carrier are adjusted. The solubility limit of PMMA relative to PS for the carrier, marked by blue diagonal lines, stands at a 70% volume fraction (Vf).
