碩士 === 國立臺灣科技大學 === 高分子工程系 === 93 === Absract In this study, a series of gelatin-alcohol surfactants was prepared by the reaction of gelatin, a hydrolyzate of collagen, with alcohols containing methanol, pentanol, decanol, dodecanol, and octadecanol. The structure of these surfactants was confirmed by FT-IR, 1H-NMR and elemental analysis. The experimental results showed that these surfactants exhibited excellent surface-active properties　including reducing surface tension, foaming, contact angle, streaming current reading, pH buffer capacity, dispersing power, chelating ability for calciumion, scouring and bleaching in cotton, interactions between the dye and the surfactants, and promotion and migration property in nylon Key word：gelatin、surface、surface tension、wetting power.
