OCT-Gravimetry-Video characterization of the drying process of L latex particles (diameter ∼125 nm). (a,b) Curves of the global drying rate (dw(t)/dt) and the water content in latex (kw(t)) derived from gravimetric measurement. (c1–c6) video photos at 30, 168, 190, 212, 280 and 500 min. (d) Time-lapse OCT intensity profile, derived from 2D OCT structural images at different times. (e) Drying states from the start of drying to the end of being fully dried, defined by the Gravimetry-Video characterization (above the timeline) and by the OCT imaging (below the timeline). (f1–f6) 2D OCT structural images at 30, 168, 190, 212, 280 and 500 min. Scale bars in (f1–f6): 200 μm. Black cross in (c1): OCT scanning location. Red dotted circles in (c4): drying boundary.
