介绍了一种基于斜角气相沉积聚合的自下而上存款结构化聚对苯二甲撑（PPX）聚合物薄膜的新工艺。在该方法中，将通过化学官能化的对二甲苯前体的热解产生的单体蒸气以倾斜角度朝向表面引导以引发结构化聚合物生长。倾斜沉积诱导PPX纳米纤维的生长，导致包括类似于100- 150 nm直径纳米柱的簇的纳米结构化表面。这些膜的形态可以通过在斜角沉积期间操纵衬底旋转来控制（即，螺旋形、人字形和柱状形态）。用原子力显微镜和扫描电子显微镜对PPX薄膜的形貌进行了表征。(C)2008 Elsevier B. V.保留所有权利。
A novel bottom-up process to deposit structured poly(p-xylylene) (PPX) polymer films, based on oblique angle vapor deposition polymerization, is introduced. In this process, monomer vapors produced by pyrolysis of chemically functionalized p-xylylene precursors are directed at an oblique angle towards a surface to initiate structured polymer growth. Inclined deposition induces growth of PPX nanofibers leading to a nanostructured surface comprising clusters of similar to 100-150nm diameter nanocolumns. Morphology of these films can be controlled by manipulating the substrate rotation during oblique angle deposition (i.e., helical, chevron and columnar morphology). The morphology of the nanostructured PPX films are characterized by atomic force microscopy and scanning electron microscopy. (C) 2008 Elsevier B.V. All rights reserved.
