应用外部电容耦合式等离子体聚合方法,首次得到了丁醛聚合物,研究了其聚合规律,找到了较好的聚合条件。通过元素分析和红外光谱分析,证实丁醛等离子体聚合物为交联结构;电子衍射分析和X-射线衍射分析发现聚合物中存在部分结晶,而且部分以单晶形式存在;表面能测定表明丁醛等离子体聚合物为疏水性。并初步探讨了反应机理。 For the first time, butyraldehyde polymer was obtained by external capacitive coupled plasma polymerization. The polymerization rules were studied and good polymerization conditions were found. By elemental analysis and infrared spectroscopy analysis, it was confirmed that the butanal plasma polymer was a cross-linked structure; electron diffraction analysis and X-ray diffraction analysis showed that the polymer was partially crystallized and partially existed as a single crystal; Aldehyde plasma polymers are hydrophobic. The reaction mechanism was discussed preliminarily.
