“…[14,15] TCO functional particles shield NIR through the plasmon resonance effect, which currently can be prepared on a large scale, so they are favored by the majority of researchers. Li et al [16] prepared transparent AZO/epoxy composite thermal insulation coating by incorporating AZO nanoparticles into a transparent epoxy matrix and the effect of AZO content on the optical and thermal insulation properties of the composite coating was studied. However, AZO has a lower reflectivity in the NIR region, which leads to the poor heat insulation effect, and indium (In) in ITO as a rare metal element has a higher cost.…”

Near‐infrared (NIR) shielding is essential not only in the building and automobile glass films but also in achieving energy conservation. However, effectively shielding NIR and maintaining high transmittance in the visible light region have been great challenges in the past decade. Recently, hexagonal cesium tungsten bronze (CsxWO3) nanoparticles have been widely studied due to the excellent transparency in the visible light region and strong heat‐shielding ability in the NIR region. Herein, a design concept of transparent polyvinyl chloride (PVC)/CsxWO3 composite film, as a heat insulation material for glasses, was proposed. To achieve this purpose, the PVC/CsxWO3 composite film was prepared by incorporating CsxWO3 slurry with better dispersion than traditional CsxWO3 nanoparticles powder into a transparent PVC matrix. By the UV‐Vis‐NIR spectrophotometer characterization, the PVC/CsxWO3 composite film containing 2.1 phr CsxWO3 slurry displays high blocking of NIR (78%) and high transmittance of visible light (76%). In order to further understand the actual heat insulation effect from the PVC/CsxWO3 composite films, the indoor sunlight simulation test and outdoor cooling experiment with solar illumination variations were carried out, which both showed heat insulation that is superior to the antimony tin oxide and indium tin oxide thin films prepared in our previous work. In addition, the mechanical property of PVC/CsxWO3 composite films shows almost no change with the increase of CsxWO3 slurry. The PVC/CsxWO3 composite films simultaneously achieve excellent shielding of NIR and high transmittance of visible light, which makes it an ideal material to alleviate the current building energy consumption issues.

This article presents the comparison of mechanical and dry sliding wear peculiarity of zinc oxide (ZnO)-filled polyester composites, fabricated by two different techniques. These two techniques are simple mechanical stirring and vertical centrifugal casting. ZnO filled polyester based homogeneous composites are fabricated by simple mechanical stirring technique whereas composites fabricated by vertical centrifugal casting technique are functionally graded materials (FGMs). Dry sliding wear tests are performed over a range of sliding velocity (1.57-3.66 m/s), normal load (10-30 N), filler content (0-20 wt%), and sliding distance (1000-3000 m) using a pin-on-disc apparatus. This study establishes that the FGMs exhibit superior mechanical properties (except tensile strength) and wear resistance as compared with homogeneous composites. Among all the fabricated composites, FGMs filled with 20 wt% ZnO filler has maximum hardness and flexural strength i.e. 70 HRL and 39 MPa, respectively. Compressive and impact strength is maximum for 10 wt% ZnO filled FGMs with 36 MPa and 1.3 J, respectively. The tensile strength of homogeneous composites is 21.7% higher as compared with FGMs for 10 wt% of ZnO filler loading. FGM filled with 20 wt% of ZnO filler has minimum specific wear rate of 0.33 3 10 25 mm 3

“…The absorption process is physical, and a previous study showed that ZnO can fully absorb UV rays . Moreover, enhancements in the thermal stability and improvements in the UV degradation of polymeric materials have been claimed by many researchers .

In this study, the effects of the incorporation of microsized zinc oxide (ZnO) on multiwalled carbon nanotube (MWCNT)-reinforced palm-oil-based polyester (POPE) were investigated in terms of the UV absorbability, mechanical strength, thermal stability, surface resistivity, and morphology. POPE was prepared by alcoholysis and an esterification process with glycerol, palm oil, and phthalic anhydride. The MWCNTs were dispersed into POPE under in situ conditions during the esterification reaction, whereas ZnO was distributed into the MWCNT-filled POPE resin with an ultrasound technique. The surface morphology was examined to understand the dispersion of the fillers inside the polymer matrix with field emission scanning electron microscopy. In addition, UV absorbability was observed with a UV-visible spectrophotometer. From the results analysis, the surface resistivity was found to be unchanged by the presence of the ZnO particles. In addition, incorporation of ZnO improved the UV absorbability. Moreover, the tensile strength of the ZnO-based POPE was found to be slightly lower compared with that of the MWCNT-filled POPE.
