In this paper, one-dimensional TiO₂ nanochains were prepared by polymerization of azide-alkyne click reactions. As a first step, the TiO₂ nanoparticles (NPs) were esterified with 2-bromopropionic bromide, grafted by atom transfer radical polymerization (ATRP) of styrene, followed by azidation (TiO₂-PS-N₃). Second, another part of the TiO₂ NPs were modified by propargyl bromide (TiO₂-C≡CH). By azide-alkyne click reactions between the azide and alkyne-terminated TiO₂ NPs, one-dimensional TiO₂ nanochains linked by polystyrene (PS) was successfully synthesized. The chemical structure of the product was characterized using FTIR, TGA and TEM.

TiO ₂纳米颗粒到一维纳米链的点击聚合和表征

本文通过叠氮化物-炔烃点击反应的聚合制备了一维TiO ₂纳米链。第一步，将TiO ₂纳米颗粒（NPs）用2-溴丙溴化物酯化，通过苯乙烯的原子转移自由基聚合（ATRP）接枝，然后进行叠氮化（TiO ₂ -PS-N ₃）。其次，另一部分TiO ₂ NP被炔丙基溴（TiO _2- C≡CH）改性。通过叠氮化物-炔烃的点击反应，叠氮化物与炔烃封端的TiO ₂ NPs，一维TiO ₂成功地合成了由聚苯乙烯（PS）连接的纳米链。使用FTIR，TGA和TEM对产物的化学结构进行表征。
