Figure 6.

The schematic modes of the formation of separated phase domains of the copolymer cured under different surface-contact covers have been developed. Two different kinds of particles (white and gray) represent the hydrophilic phase and hydrophobic phase, respectively. It should be mentioned that the particles plotted in this scheme do not represent the real shape of contrasted phases. The pictures portrayed that the attraction of the hydrophilic phase to the hydrophilic surface-contact cover caused higher, but soft domains (a), however, the attraction of the hydrophobic phase to the hydrophobic surface-contact cover caused higher and hard domains (b). Thus cover glass was preferred as a suitable cover material because the copolymer surface phases would not be attracted in a very limited manner and thus, would maintain their original state (c).
