MD studies of the micellar axial growth mechanism. a The typical conformation of POSSm-PEGn oligomer in water with various chain lengths at (L1) 1, (L2) 2, (L3) 4, and (L4) 6. Water molecule is not shown for clarity. The inner cube represents the POSS core, wherein the yellow cylinder represents the silicon (Si) atom and the red cylinder represents the oxygen (O) atom. The outer linkage represents the PEG shell, wherein the red cylinder represents the oxygen (O) atom, the yellow cylinder represents the sulfur (S) atom, the wathet blue cylinder represents the carbon (C) atom, and the white cylinder represents the hydrogen (H) atom. b The average Rg for PEG chain on the side and middle of POSS molecules (see Supplementary Table 1 for the detailed simulation parameters)
