| Abstract: | 本研究是以不同分子量之聚乙二醇(polyethylene glycol, PEG)及聚乳酸(PLA)為原料製備一系列環保型雙分子界面活性劑，合成一系列之產物皆以紅外線光譜分析(FT-IR)確認其結構，再針對產物之物理及化學性質加以探討，其中測試性質包含：濕潤性、起泡性、耐酸性及耐鹼性等，結果顯示一系列產物皆具有良好的界面性質。
In this study, we synthesis a series of Eco-friendly Hydrophilic modification Gemini surfactants by the reaction of polylactic Acid and the Polyethylene glycol of different molecular weights. The structure of these surfactants were confirmed by FT-IR. And discussion that physical and chemical properties, including wettability, foaming, acid and alkali resistance, the result displays that a series of result all has the good surface properties. |
