Super‐hydrophobic surfaces, with a water contact angle (CA) greater than 150°, have attracted much interest for both fundamental research and practical applications. Recent studies on lotus and rice leaves reveal that a super‐hydrophobic surface with both a large CA and small sliding angle (α) needs the cooperation of micro‐ and nanostructures, and the arrangement of the microstructures on this surface can influence the way a water droplet tends to move. These results from the natural world provide a guide for constructing artificial super‐hydrophobic surfaces and designing surfaces with controllable wettability. Accordingly, super‐hydrophobic surfaces of polymer nanofibers and differently patterned aligned carbon nanotube (ACNT) films have been fabricated. 相似文献

The inside cover shows light emission from within the channel of an ambipolar field‐effect transistor based on the green‐light‐emitting conjugated polymer F8BT in a bottom contact/top gate structure, as reported by Sirringhaus and co‐workers on p. 2708. It visually demonstrates the formation of separate electron and hole accumulation layers in ambipolar transistors and radiative recombination of charge carriers where the two layers meet (schematic), which is controlled by the applied voltages. 相似文献
