Fig. 4: Kinetically driven mechanism for the monomicelle one-dimensional oriented self-assembly.

a Structural characteristic of the F127/Resol monomicelle with PPO domains as the core and surrounded by resol associated PEO shells. b Schematic illustrations of the formaldehyde and ammonia concentrations in the solution varied with the reaction time under different reaction temperatures (mode I: 80 °C; mode II: 100 °C; mode III: 140 °C). c Schematic illustration of the fabrication of cubic OMCFs (Route1) and hexagonal OMCFs (Route 2) using the kinetically driven monomicelle oriented self-assembly approach.
