“…The infrared emissivity was as low as 0.793 when the weight ratio of ZnO:(Al, La) powders was 55 wt.%, which could be matched in the surroundings of withered grass or rock under the non-sunshine time. According to our previous report [17] , it confirmed that ZnO:(Al, La) nanoparticles had the capacity of reducing the infrared radiation. The more content of ZnO:(Al, La) powders, the lower the infrared emissivity.…”

“…However, there is little study about infrared stealthy performance of electrospinning nanofibers. 3 In this paper, the infrared stealth nonwovens are prepared via direct electrospinning, with polyacrylonitrile (PAN) which has good mechanical strength and excellent thermal stability, and infrared camouflage material ZnO:(Al, La) nano particles [17] . The infrared stealthy property of ZnO:(Al, La)/PAN nonwovens with various ZnO:(Al, La) contents were characterized by IR-2 dual-band infrared emissivity measuring instrument and infrared imaging systems.…”

The current focus in Swedish policy towards national security and high-end technical systems, together with a rapid development in multispectral sensor technology, adds to the utility of developing advanced materials for spectral design in signature management applications. A literature study was performed probing research databases for advancements. Qualitative text analysis was performed using a six-indicator instrument: spectrally selective reflectance; low gloss; low degree of polarization; low infrared emissivity; non-destructive properties in radar and in general controllability of optical properties. Trends are identified and the most interesting materials and coating designs are presented with relevant performance metrics. They are sorted into categories in the order of increasing complexity: pigments and paints, one-dimensional structures, multidimensional structures (including photonic crystals), and lastly biomimic and metamaterials. The military utility of the coatings is assessed qualitatively. The need for developing a framework for assessing the military utility of incrementally increasing the performance of spectrally selective coatings is identified.

“…The major templates used for the preparation of hybrid materials can be produced at present with monodispersed colloid particles or controlled morphology (such as membrane pore structure). 27 Therefore, nano-ZnO can be potentially applied to UV-shielding materials, 25,26 catalysts, 21,22 antibacterial materials, 23,24 sensors, 19 solar cells 28,29 and so forth. This method has been used to synthesize nanoparticles of II-VI compounds (e.g., CdS, PbS), 10,11 III-V compounds (GaAs) 12 and a wide range of metal oxides including TiO 2 , 13 ZnO, 14 Fe 2 O 3 , 15 and PbO, 16 Fe 3 O 4 .…”

This work presents a facile approach to synthesize P(VC-co-AAEM) (vinyl chloride copolymerized acetoacetoxyethyl methacrylate)/zinc oxide (ZnO) nanocomposite particles with raspberry-like shape by a nano-coating technique. It is proved that the interactions between the b-diketone groups embedded in AAEM and ZnO precursors are crucial to forming the raspberry-like morphology, as such, the content of AAEM has a significant effect on the nucleation and growth of ZnO nanocrystals on the P(VC-co-AAEM) beads. SEM analysis demonstrated that ZnO nanocrystals were deposited on the surface of template nanoparticles as small clusters with different sizes and quantity, depending on the reaction parameters. X-ray diffraction of the P(VC-co-AAEM)/ZnO nanocomposite particles revealed that the addition of functionalized PVC beads lowered the formation of ZnO nanocrystals due to the constraining effect of the ZnO-AAEM interaction on the mobility of ZnO precursors. Additionally, such PVC/ZnO composite particles were found to have excellent foamability of nanometer-sized pores, which could have various potential applications in sound insulation and thermal insulation. Scheme 1 Schematic representation of the steps involved in the fabrication of P(VC-co-AAEM)/ZnO composite particles and foaming: (a) preparing functionalized P(VC-co-AAEM) particles, (b) fabrication of P(VC-co-AAEM)/ZnO nanocomposite particles, (c) absorbing ADC, (d) foaming in mould. 36846 | RSC Adv., 2015, 5, 36845-36857 This journal is
