Fig. 2: Interpenetrating network in the fibrous micromesh via Van der Waals force tuning phase separation.

a Consecutive schematics of phase separation with intensive aggregation. (i) L-L separation; (ii) aggregation-assisted coarsening and (iii) the resultant fibrous micromesh. b (left) Adhesion AFM images of the elastomer-rich and semiconductor-rich regions in the FMM- and LS films. The scale bar is 180 nm and 410 nm, respectively. Both films were fabricated using spin-coating method with the speed of 1500 rpm. The corresponding topography AFM images were detailed in Supplementary Fig. 13. (right) Statistical profiles of DMT modulus extracted from the adhesion AFM revealed the continuous network and macro phase separation in FMM film and LS film, respectively. The filled/unfilled boxes illustrate adhesion distribution of hybrid aggregates. c (left) Detailed schematic of the AFM mapping in the cross-section region and the tracks of height and modulus. See the list of Abbreviations for full chemical names. (right) Illustration of the semiconductors and insulator distribution within the film. The green panel represents the N2200, the yellow panel represents the insulator.
