含刚性基团Gemini表面活性剂的合成与理化性能研究的开题报告 摘要： 本文拟对含刚性基团Gemini表面活性剂的合成及其理化性能进行研究。Gemini表面活性剂具有许多优良性质，如表面活性高、胶团形成能力强、抗氧化性好等，但常规的Gemini表面活性剂仍存在一些问题，如水溶性差、分散性差等。因此，本文准备通过引入刚性基团来改进这些问题，并研究其理化性能。具体研究内容包括：1）合成含刚性基团Gemini表面活性剂；2）测定其表面活性、临界胶束浓度、溶剂亲和力等性质；3）研究其在水中的分散性；4）探究其抗氧化性能。本文的研究对于改进Gemini表面活性剂的性能具有一定的意义。 关键词：Gemini表面活性剂、刚性基团、表面活性、分散性、抗氧化性能 Abstract: This paper intends to study the synthesis and physicochemical properties of Gemini surfactants containing rigid groups. Gemini surfactants have many excellent properties, such as high surface activity, strong ability to form micelles, good antioxidant properties, but conventional Gemini surfactants still have some problems, such as poor water solubility, poor dispersibility, etc. Therefore, this article plans to improve these problems by introducing rigid groups and study their physicochemical properties. The specific research content includes: 1) synthesis of Gemini surfactants containing rigid groups; 2) determination of their surface activity, critical micelle concentration, solvent affinity and other properties; 3) study their dispersibility in water; 4) explore their antioxidant properties. The research in this article is of certain significance for improving the properties of Gemini surfactants. Keywords: Gemini surfactant, rigid group, surface activity, dispersibility, antioxidant properties.
