Figure 3

Characterization of PDMS-PDMS stamping to a cross pattern. (A) Image of the cross after stamping with PFTCS highlighted in green. (B) Surface coverage with respect to stamping time and temperature. (C) Image of the corresponding stamps after stamping for 30 min. (D) Average RMS height across three locations of each stamp showing the uniformity of transfer. Inset image describes where A and C where obtained. All experiments were performed in triplicate.
