AIM: To evaluate the potential fungicidal activity of a cationic polymer polyethylenimine (PEI).
目的：评估阳离子高分子聚合物聚乙烯亚胺(PEI)的潜在抗真菌活性。
The result showed that anionic and cationic type surfactants would form a substance having no surface activity, and could not be used together.
实验结果表明，阳离子表面活性剂与阴离子表面活性剂复配容易生成不具有表面活性的物质，故不宜一同使用。
