    摘要:

    紫外光照条件下(=254 nm)引发自组装在α-FeOOH纳米粒子表面的10,12-二十五碳二炔酸(DA)聚合,得到聚10,12-二十五碳二炔酸/α-FeOOH纳米复合材料(PDA/α-FeOOH),利用XRD、SEM、DLS对该复合材料的结构、形貌及粒径大小进行了表征。热致变色实验结果显示:复合材料在30~80℃间呈“蓝-红”的可逆变化,考察了α-FeOOH用量、光聚合时间对PDA/α-FeOOH纳米复合材料热致可逆变色的影响。结果显示:经紫外光照时间10 min聚合得到的蓝色PDA/α-FeOOH(m(DA):m(α-FeOOH)=3:1)复合材料加热变色最快,60℃完全变为红色,最大吸收波长从650 nm蓝移至540 nm,冷热循环实验证明PDA/α-FeOOH复合材料具有良好的稳定性。

    Abstract:

    10,12-Pentacosadiynoic acid(DA)-assembled on the surface of α-FeOOH was irradiated with ultraviolet light (=254 nm) to obtain polydiacetylene/α-FeOOH(PDA/α-FeOOH) nanocomposites. The structure and morphology of nanocomposites were analyzed by XRD, SEM and DLS. Thermochromism experiment showed that PDA/α-FeOOH had a reversible change from blue to red between 30℃ and 80℃. The effects of irradiation time and amount of α-FeOOH on reversible thermochromic of PDA/α-FeOOH nanocomposites were investigated. The results revealed that bule PDA/α-FeOOH nanocomposites(m(DA):m(α-FeOOH)=3:1) with UV light irradiated for 10 min was the fastest color change. When the composites were warmed at 60℃, its color changed red and the maximum absorption wavelength happened shift-blue from 650 nm to 540 nm. The heating and cooling cycles indicated that PDA/α-FeOOH composites had higher thermal stability.
