Extended Data Fig. 7: Pressurization of negatively deflected films.
From: A molecularly impermeable polymer from two-dimensional polyaramids
(A) Change in bulge deflection with respect to the overpressure applied during the N2 pressurization process. Error bars represent standard deviations from n = 17, 10, 10, 8, and 12 samples for applied pressures of 20, 50, 100, 150, and 200 kPa, respectively. The blue line is cubic fit intended to guide the reader’s eye. (B) Change in the absolute deflection of bulges with respect to time after being pressurized with 150 kPa N2 over atmosphere. (C-D) Optical images of the 10-µm diameter Si/SiO2 wells sealed with a 35-nm 2DPA-1 film. Red circles mark the wells that were tracked via AFM measurements. (C) Image taken before pressurization with 150 kPa N2. (D) Image taken after pressurization with 150 kPa N2.
