In situ Pd-catalyzed cyclopentene polymerization in the presence of multi-walled carbon nanotubes (MWCNTs) is demonstrated to effectively render, on a large scale, polycyclopentene-crystal-decorated MWCNTs. Controlling the catalyst loading and/or time in the polymerization offers a convenient tuning of the polymer content and the morphology of the decorated MWCNTs. Appealingly, films made of the decorated carbon nanotubes through simple vacuum filtration show the characteristic lotus-leaf-like superhydrophobicity with high water contact angle (>150°), low contact angle hysteresis (<10°), and low water adhesion, while being electrically conductive. This is the first demonstration of the direct fabrication of lotus-leaf-like superhydrophobic films with solution-grown polymer-crystal-decorated carbon nanotubes.
原位钯催化的多壁碳纳米管（MWCNTs）存在下的环戊烯聚合反应被证明能够大规模有效地制备出聚环戊烯晶体修饰的多壁碳纳米管。在聚合反应中控制催化剂负载量和/或时间，可以方便地调节聚合物含量以及修饰后的多壁碳纳米管的形态。吸引人的是，通过简单的真空过滤由修饰后的碳纳米管制成的薄膜具有荷叶状超疏水性，具有高水接触角（>150°）、低接触角滞后（<10°）和低水附着力，同时具有导电性。这是首次展示用溶液生长的聚合物晶体修饰的碳纳米管直接制备荷叶状超疏水薄膜。
