Wet transfer technique of patterning surfaces with laser-aligned C116 PS-b-P2VP BCP films. The flotation of the aligned film on the water surface after dissolution of the poly(4-styrene sodium sulfonate) sacrificial layer (a). The aligned film retains the high quality of morphological alignment after it is collected on a fresh Si wafer and metalized to produce an array of Pt nanowires (b). The wires conformally coat a sharp step near the edge of the wafer (c). Two-layer rectangular Pt nanomesh obtained after single-step metalization performed after stacking the aligned BCP films (d).
