| 摘 要： | 用溶胶凝胶法和喷雾干燥技术在云母微粉表面包覆了不同nW/nV的掺钨V2O5溶胶,分别采用热分解和碳热还原得到了掺钨VO2/云母复合粉体。通过XRD、SEM对复合粉体进行了物相组成、微观形貌的表征。将复合粉体添加到紫外光固化树脂中形成复合薄膜,通过FTIR测试了复合薄膜相变过程中的红外透过率图谱,并通过DSC测试了复合粉体的相变温度(Tt)。结果表明两种热处理方法均得到了VO2(M),VO2晶体以蠕虫状附着在云母表面,同时钨的掺入使云母表面的VO2颗粒更加细小。不同掺杂量的复合粉体均表现出较优异的热致变色性能,相变前后在2 200 cm-1波数处的红外透过率变化量(ΔTr)均超过20%。随着nW/nV增加,复合粉体的ΔTr逐渐减小,Tt逐步降低,同时相变陡然性减缓。
