Figure S1. AFM height image and corresponding section analysis (2 x 2 µm) of cellulose nanocrystals derived from cotton fiber.

CNC dispersions were diluted to the desired concentration and spin-coated onto UV-treated silicon wafers with an anchoring polymer at 4000 rpm. The deposition of the suspension was performed on a substrate that was then spun for 30 seconds. The surfaces were then dried at 80 °C for 1 hour. The resulting CNCs were determined to have widths ranging ~4-12 nm and lengths from ~100-200 nm according to AFM height images.
