The four samples were measured on a Mira3 system (TESCAN) operated at 30 kV and a working distance of 5 mm. Folders named “Figure-1e, Figure-1f” contain width and length data of CMPs-S, CMPs-M, CMPs-L, and CMP-XL, respectively. Folder named “Figure-1g” contains a picture (taken by a regular camera) of light passing through suspensions of CMPs-L, CMPs-M, CMPs-S, CMPs-XL (concentration is 0.1% in weight percentage) and water.
