A versatile pilot‐scale reactor has been designed in such a way that it can be readily converted from a dielectric barrier discharge “PECVD” operating mode into a photoinitiated “PICVD” one; in the latter, low‐pressure mercury (Hg) lamps replace the high‐voltage glow discharge plasma. Both processes operate at ambient temperature and atmospheric pressure, 100 kPa, using acetylene (C₂H₂) monomer. In both sets of experiments, it was found that efficient gas‐to‐solid conversion can occur in the form of a nanoparticulate amorphous hydrocarbon polymer‐like material. It was found that in the PICVD case, great care was required to exclude even traces of O₂ contamination, because it not only reduced the growth rate of solid, but the latter then became highly oxidized ([O] ~50 at.%) and water‐soluble.

大气压下乙炔的有机涂层：紫外线与等离子

设计了一种多功能的中试反应器，可以轻松地将其从介电势垒放电“ PECVD”操作模式转换为光引发的“ PICVD”模式。在后者中，低压汞（Hg）灯代替了高压辉光放电等离子体。两种方法均使用乙炔（C ₂ H ₂）单体在环境温度和大气压100 kPa下运行。在这两组实验中，均发现以纳米颗粒状无定形烃类聚合物状材料的形式可以实现有效的气固转化。发现在PICVD情况下，需要格外小心，以排除甚至痕量的O ₂ 污染，因为它不仅降低了固体的生长速度，而且后者随后变得高度氧化（[O]〜50 at。％）和水溶性。
