This mesh size, judged from two-dimensional images, provides us with a parameter to directly analyze and compare the structures in different microscopy images, although it is somewhat different from the actual mesh size of three-dimensional network.

26. In references [5] and [6], network-like structures obtained by temperaturechange-induced asymmetric dynamics and VPS are not so clear and with smaller mesh size (<10 μm), compared with that shown in Figure 1c. The differences may result from the different molecular structure of the slower dynamic component, PBDT, with a typically semi-rigid conformation, while others are without.
