摘要/Abstract

摘要：

在氢气和甲烷环境下，利用辉光等离子体放电制备了聚合物。该聚合物的外观特征为白色、略发黄、柔软、丝状，易碎为粉末状。聚合物中含有–CH3，–CH2，C–O，–C=C–，–OH等官能团且不存在单质形态的碳。有机溶剂溶解分析发现，常温下该聚合物在各种有机溶剂中的溶解性极小、小于0.1mg.ml^-1，几乎不溶于甲苯中，在不同有机溶剂中的溶解度大小依次为，S丙酮>S三氯甲烷>S乙醇>S环己醇>S甲苯。低温等离子体的离化率越高、中性气体被极化时的极化半径越大、环境温度越低以及介电常数越小，聚合物的生成能力越强。

Abstract:

Polymers are prepared under methane plasma environment, and appear to be white, slightly yellow, soft thread-like powders and floc under optical microscope. The polymers contain –CH3, -CH2, C-O, -C=C-, -OH etc. functional groups, but no simplex carbons. It is found that the solubility of this polymer is less than 0.1mg.ml^-1 in different organic solvent. The productivity of the polymers is higher under a plasma environment with higher ionization, higher polarization of neutral gas, lower environment temperature and less permittivity.
