本研究是以不同聚乙二醇(polyethylene glycol, PEG)及回收型聚乳酸(Re-PLA)為原料合成綠色 雙分子界面活性劑之開發研究，所合成的一系列產物以紅外線光譜分析(FT-IR)確認其結構， 針對產物性質及物性予以探討，測試性質包括表面張力、乳化性、黏度，測試一系列產物之 乳化性。

This research is to use different PEG and Re-PLA fusion the development research of the double molecule Surfactant for the raw material, a series of outcome synthesized confirms its structure by FT-IR, The purpose is to give the discussion to the Product quality and Physicality. The test quality includes: Surface tension, Emulsification, Viscosity and Emulsifying properties of a series of test product.
