| 摘 要： | 通过乳液聚合法成功地将具有红外屏蔽功能的纳米ATO粒子包覆在聚合物内。电子透射电镜观察显示纳米ATO粒子存在于杂化乳胶粒子内。当添加的ATO重量比率为2.7%时,包覆效率达到最大值54.5%。紫外-可见光-近红外光谱结果显示,随着添加的ATO重量比率的增加,近红外透过率逐渐减少,而可见光透射率变化很小。含纳米ATO的杂化膜显示出优异的高可见光透过率而近红外被屏蔽的能力,可用于节能的透明隔热涂料。

| Abstract: | The nano-ATO particles with the shielding ability of infrared were encapsulated successfully via emulsion polymerization.Transmission electron microscopy shows that nano-ATO particles exist in hybrid latex particles.The encapsulation efficiency of nano-ATO reaches to the maximum value of 54.5% with 2.7wt% added nano-ATO weight ratio.The ultraviolet-visible-near infrared spectra show that the transmittance of hybrid film in near infrared region decrease and changes a little in visible region with the increas... |
