Fig. 6. Designability of the surface wettability pattern.

Fig. 6

(A) SEM image of the cross section parallel to the cold substrate, showing a cross-aligned lamellar structure. (B) Three-point bending curves of the HA/PMMA composites showing high anisotropy. (C) SEM image of the cross section parallel to the cold substrate, showing a circular long-range lamellar structure orients perpendicular to the wettability gradient. The orientation analysis by software ImageJ confirms the circular structure. (D to F) Enlarged SEM images from three regions showing the lamellar structure with different orientations guided by the wettability gradient. (G) Compression curves of the HA/PMMA composites with circular and multidomain lamellar structures prepared with radial gradient and homogeneous surfaces, respectively.
