可降解淀粉微球制备工艺的优化

Optimization of preparation technology of degradable starch microspheres

以可溶性淀粉为原料,以反相乳液聚合的方法合成可降解淀粉微球(DSM),通过单因素试验和均匀试验探讨各因素对DSM粒径的影响。结果表明,在诸因素中搅拌速度对DSM的影响最大,其次为淀粉乳的浓度。

soluble starch was taken as raw materials. DSMs were synthesized by the way of inverse emulsion polymerization. Effect of different factors on diameter of DSMs was compared by single factor design and uniform design. The result showed that the rate of emulsion had remarkable effect, and the followed was the concentration of soluble starch.
