- And the diblock copolymer PI-b-PEO with an azide group was obtained by a series of modification of the hydroxyl group at the junction point. 然后将羟基的保护基团脱除，并通过一系列反应将得到的“活性”羟基依次溴化和叠氮化，最后得到链段中间含叠氮基团的嵌段聚合物PI-b-PEO。
- Compared with polyethylene as a standard sample,GAP has higher surface free energy because there are many hydroxyl groups and azide group in the surface of the GAP molecule. 与聚乙烯相比,GAP的总表面的自由能较高,这主要是因为GAP表面含有羟基和叠氮基团。
- A new method of using photoactivable ester with azido group was described to immobilize urease on polyether sulfone(PES) film surface. 我们利用含芳香叠氮基的光活性酯将脲酶光固定在聚醚砜 (Polyether sulfone,pes)膜的表面。
