Preparation and characterization of poly(MMA–BA)/nano-ATO hybrid latex via miniemulsion polymerization

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-visiblenear 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.

Synthesis and applications of MANs/poly(MMA-co-BA) nanocomposite latex by miniemulsion polymerization

“…For the MANs/PMB with 10 wt% MANs, the temperature difference is up to about 6.5°C ( figure 7 b ). Meanwhile, in good agreement with the results of other studies [ 34 , 48 ], the transmittance of the MANs/PMB nanocomposite decreases as the weight content of MANs increases. Owing to the precisely tailored core-shell structure, the nanocomposite film shows a more excellent heat-blocking property than that reported in the literature [ 34 , 48 ].…”

These results indicate that the MANs/PMB nanocomposite latex has good heat-blocking properties and can be used in windows of buildings and vehicles and other thermal management applications.…”

“…Herein, we report the preparation of a transparent thermal insulation aqueous latex with irregular distribution of ATO NPs by miniemulsion polymerization. As a result, the MPS-functionalized ATO NPs (MANs)-embedded PMB latex nanocomposite can be tailored more precisely than other NPs-embedded nanocomposites [ 34 ]. We first introduce a polymerizable anionic surfactant DNS-86 (allyloxy polyoxyethylene(10) nonyl ammonium sulfate) to synthesize highly stable, transparent core-shell nanocomposite with infrared shielding properties via miniemulsion polymerization in the presence of ATO, a key filler, which was functionalized with reactive 3-methacryloxypropyl trimethoxysilane (MPS) to promote intercalation of water-insoluble monomers methyl methacrylate (MMA) and butyl acrylate (BA).…”

Transparent polymer nanocomposites: An overview on their synthesis and advanced properties

“…However, some studies have been reported on IR filtering transparent nanocomposites. Zhang et al [223] fabricated a 60 µm thick transparent nanocomposite made of a PMMA-PnBA copolymer matrix filled with ATO nanoparticles. The nanocomposite transmittance in the near IR range (800-2600 nm) decreased strongly when increasing the ATO nanoparticles content from 3 to 10 wt%, while it was transparent in the visible domain.…”

The Design and Preparation of Transparent Hybrid Composite Thin Films with Excellent Optical Properties and Improved Thermal Insulation by Optimized Combination of Nanomaterials

“…In this paper, we selected cesium-doped tungsten oxide (CTO) 9,10 and lanthanum boride (LaB 6 ) 11,12 to prepare hybrid materials with extrapolated optical properties through orthogonal translation experiments from graphene. 13,14 Different films comprised of cesium-doped tungsten oxide (CTO), lanthanum boride (LaB 6 ), antimony-doped tin oxide (ATO), 15,16 tin-doped indium oxide (ITO) 17,18 and antimony and tin-doped indium oxide (IATO) 19,20 were synthesized by adjusting the proportion of polyvinyl butyral (PVB), 21,22 dibutyl phthalate (DBP) 23 and solvents (ethanol, ethyl acetate and acetylacetone) whilst optimizing the film forming conditions. The resulting films were characterized and analyzed for their optical properties in which the best one has obtained 86% maximum transmittance in visible light range, 90% and 50% blocking rate on UV and IR and SHGC as 0.61.…”
