A convenient approach to synthesize patterned carbon nanotubes (CNTs) of three morphologies on printed substrates by combination of microcontact printing (microCP) and a plasma-enhanced chemical vapor deposition (PECVD) process is presented. Micelles of polystyrene-block-poly-(2-vinylpyridine) (PS-b-P2VP) in toluene were used as nanoreactors to fabricate FeCl3 in the core domains, and the complex solution was used as an ink to print films with polydimethylsiloxane (PDMS) stamps, different morphologies (porous, dots and stripes patterns) of the FeCl3-loaded micellar films were left onto silicon substrates after printed. After removing the polymer by thermal decomposition, the left iron oxide cluster arrays on the substrate were used as catalysts for the growth of CNTs by the process of PECVD, where the CNTs uniformly distributed on the substrates according to the morphologies of patterned catalysts arrays.
本文提出了一种通过微接触印刷(microCP)和等离子体增强化学气相沉积(PECVD)工艺相结合的方法,在印刷基板上合成三种形态的图案化碳纳米管(CNT)。以聚苯乙烯-嵌段-聚(2-乙烯基吡啶)(PS-b-P2VP)在甲苯中的胶束作为纳米反应器,在其核心区域制备FeCl₃,并将该复合溶液用作油墨,用聚二甲基硅氧烷(PDMS)印章印刷薄膜。印刷后,不同形态(多孔、点状和条纹图案)的负载FeCl₃的胶束薄膜留在硅基板上。通过热分解去除聚合物后,基板上剩余的氧化铁簇阵列用作PECVD工艺中CNT生长的催化剂,其中CNT根据图案化催化剂阵列的形态均匀分布在基板上。
