Based on the previous experiments, we choose CNTs/CdS core-shell nanowires as inorganic materials and poly(benzyl-ether) dendrons with thiol functionalities as organic solubilizer. The solubility of CNTs/CdS core-shell nanowires in normal solvents was expected to improve through chemical interactions between core-shell nanowires and solubilizer. The enhanced solubility can improve facility in processability. It also provides a new application method in nanomaterials.
