Fig. 2

a TEM image of uniform 2D seeds generated by a heating and aging method using 2:1 blend ratio of P150-b-P222 and P222 homopolymer. Numbers in the image indicate the average width (Wn), length (Ln), and dispersity (Đw or ĐL). b FFT pattern from the HR-TEM image of the single 2D seed showing three main d-spacings of 10.3, 18.5, and 16.1 Å and their corresponding (hkl) planes. c Schematic representation of the formation of 2D seeds and their proposed detailed structures. Also included is their crystal array and observed crystal growth rates. d AFM image of 2D seeds and e height profile along the white lines shown in the AFM image, indicating the average height (Hn).
