Figure 2. (A) Diagram of the preparation process of photothermal PDMS/CNT composites with different structure; These inserted SEMs show the surface (i) and section (ii) structures of the carved sample. The picture (iii) shows macroscopic samples of various sizes; (B) Schematic of the superhydrophobic structure and superhydrophobic phenomenon of PDMS/CNT composite showing that a drop of water does not adhere to the material surface. θ is the water contact angle. PDMS: Polydimethylsiloxane; CNT: carbon nanotube; SEMs: scanning electron microscopes.
