技術摘要:
本發明係提供一種奈米碳管懸浮液,其包含複數個奈米碳管及一嵌段共聚物分散劑,均勻分散於一溶劑中;其中該嵌段共聚物包含一疏水性嵌段及一官能基嵌段,使該奈米碳管無須經由化學改質,可直接與該官能基嵌段形成共價鍵結。本發明不須經過化學改質或添加含氟化合物,亦能形成超疏水性薄膜,其結構強韌穩定可於長時間的浸水處理、強酸強鹼之環境下或物理性刮磨,仍保有超疏水之特性。
A carbon nanotube suspension includes a plurality of carbon nanotubes and a block copolymer dispersant which are evenly distributed in a solvent, wherein the block copolymer includes a hydrophobic block and a functional group block, such that the carbon nanotubes react with the functional group block to form covalent bonds directly without undergoing chemical modification. The carbon nanotube suspension is effective in preparing a superhydrophobic film without undergoing chemical modification or the presence of a fluorine-containing compound. The superhydrophobic film thus prepared is of a tough stable structure and remains superhydrophobic when subjected to lengthy immersion treatment, exposure to a strong acid-base environment, or physical abrasion and polishing.
