Abstract
The poly(methyl methacrylate–n-butyl acrylate)/nano-antimony-doped tin oxide (ATO) hybrid latices were prepared successfully via miniemulsion polymerization in the presence of emulsifier sodium dodecyl sulfate (SDS) and costabilizer hexadecane (HD). Several factors affecting the encapsulation efficiency of nano-ATO were studied. The prepared hybrid latices were characterized using transmission electron microscopy, dynamic light scattering particle size analysis, thermogravimetric analysis, and ultraviolet–visible-near infrared (NIR) spectra. The results show that the encapsulation efficiency of nano-ATO reaches the maximum value of 78.0% with 3 wt% of nano-ATO, 4 wt% of SDS, and 4 wt% of HD, and the mean diameter of hybrid latex particles is 87.5 nm. Both the weight loss ratio and the transmittance in NIR region of hybrid film decrease with the increasing nano-ATO amount. The prepared hybrid film containing nano-ATO exhibits excellent ability for shielding IR light with high transmittance in visible region, which can be used as transparent a heat-insulating coating for energy savings.
