General description
Tween®-20是基于聚山梨酯的非离子表面活性剂。它由三种化学单位组成:
- 脂肪族酯链,可阻碍生物分子非特异性相互作用
- 脂肪链,可非共价吸附于疏水表面
- 亲水末端羟基,可以针对潜在应用进行化学修饰。

Application
Tween®-20可以作为结构导向剂,用于制备介孔氧化膜,因为它能够促进膜的纹理性能,如可控结晶度、膜形态、定制孔结构、高BET表面积和可控膜厚度。它也用于合成AuNPs/TWEEN/GO复合材料,其中Tween®-20作为AuNP(Au纳米颗粒)的还原和固定剂以及GO(氧化石墨烯)的稳定剂。
Tween®-20也可以在各种液体配方中用作乳化、增溶和润湿剂。
