介绍了一种简便的、溶剂最少化的方法来使商业坯布功能化。共轭聚合物的反应气相沉积，然后进行沉积后功能化，将普通的现成纺织品转化为明显疏水或超亲水的材料。与通过常规的溶液相硅烷化学方法施加的涂层相比，通过反应性气相沉积产生的织物涂层特别耐机械和溶剂洗涤。在每个面上具有不同润湿性的Janus织物也可以使用简单的三步气相涂覆工艺轻松创建，这是使用传统的溶液相功能化策略无法复制的。使用反应性气相沉积和沉积后功能化产生的疏水织物是有效的、可重复使用的、大体积的油-水分离器，无论是在重力过滤下还是作为可浸入的吸收剂。
A facile, solvent-minimized approach to functionalize commercial raw fabrics is described. Reactive vapor deposition of conjugated polymers followed by post-deposition functionalization transforms common, off-the-shelf textiles into distinctly hydrophobic or superhydrophilic materials. The fabric coatings created by reactive vapor deposition are especially resistant to mechanical and solvent washing, as compared to coatings applied by conventional, solution-phase silane chemistries. Janus fabrics with dissimilar wettability on each face are also easily created using a simple, three-step vapor coating process, which cannot be replicated using conventional solution phase functionalization strategies. Hydrophobic fabrics created using reactive vapor deposition and post-deposition functionalization are effective, reusable, large-volume oil–water separators, either under gravity filtration or as immersible absorbants.
