“…[7][8][9][10][11][12] The use of preformed nanoparticles of transparent conductive oxides (TCOs) is becoming an increasingly attractive alternative to thin film deposition techniques, offering great benefits for printable electronics. 15,16 However, the obtained products usually are composed of nanoparticles with a broad size distribution and variations in morphology. 13,14 Generally, liquid-phase-based processes have shown to be advantageous for the synthesis of metal oxides with high purities at moderate temperatures.…”

The non-aqueous sol-gel synthesis of aluminum zinc oxide (AZO) nanocrystals with controllable sizes and morphologies at comparatively low temperatures is presented. By varying the reaction chemistry, customized aluminum zinc oxide nanorods and nanospheres with adjustable composition and tailored morphology between 0-D and 1-D were obtained. We furthermore show that the band gap can be engineered by the Al content. Additionally, the growth kinetics and the influence of various process parameters such as the reaction temperature and precursor concentration as well as the scale-up from a 45 mL autoclave to a 500 mL reactor were investigated.Aluminum zinc oxide (AZO) nanocrystals with customized sizes and shapes were synthesized by non-aqueous reaction at moderate temperatures. The obtained morphology can be correlated with the solvent chemistry, with benzyl alcohol resulting in 1-D nanostructures whilst benzylamine leads to spherical nanoparticles.

“…When the temperature of reaction was low, HMTA was able to slowly release OH − groups, thus making the low-concentration of OH − assist in forming nanorods easily and the OH − hardly affect the morphology. However the higher hydrothermal temperature speeds up the releasing rate of OH − groups from HMTA, and more OH − groups can dissolve the (002) plane of ZnO crystal, then the ZnO nanosheets and flower begin to form 14 .…”

“…AZO seed layer was deposited on a substance by solution method, sol–gel method, magnetron sputtering methods and others, which can lower the activation barrier for the following nucleation and enhance the film adhesive force with top layer. Micro-nano AZO structures were fabricated subsequently using the hydrothermal method, plasma etching, and vapor deposition on the seed layer 14 15 . It is worth fabricating the special and micro/nano hierarchical AZO structure surface, by enhancing the surface roughness, so that superhydrophobic AZO films materials can be achieved, without involving the perfluorinated material.…”

In this communication, we present a versatile and controllable strategy for formation of superhydrophobic micro/nano hierarchical Al doped ZnO (AZO) films with a water contact angle (CA) of 170 ± 4°. This strategy involves a two-step layer-by-layer process employing an atomic layer deposition (ALD) technique followed by a hydrothermal method, and the resulting novel AZO surface layer consists of (100) dominant nano-rice-like AZO seed layer (the water CA of 110 ± 4°) covered with micro-peony-like AZO top. The growth mechanisms and superhydrophobic properties of the hierarchical AZO layer are discussed. It is believed that the present route holds promise for future success in the design and development of practical superhydrophobic materials.

“…The excess Al would form ZnAl 2 O 3 rather than replace Zn 2+ lattice site, which increases the resistivity. According to the report of Chen et al [23] and Lu et al [24], ZnAl 2 O 4 would lead to the increasing resistivity of AZO.…”

The electroconductive AZO@TiO2whiskers have been successfully preparedviacoating Al doped ZnO onto TiO2whisker. The orthogonal tests were employed to optimize the synthetic conditions. The crystallographic structure and the morphology of the AZO@TiO2whiskers and the polypropylene nonwoven fabrics modified with AZO@TiO2whiskers were characterized by X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscope, four-probe meter, and electrometer. The results showed the AZO@TiO2whiskers exhibited good electroconductive performance. Moreover, the polypropylene nonwoven fabrics modified with AZO@TiO2whiskers revealed excellent antistatic performance indicating wide application of AZO@TiO2whiskers in the antistatic textiles.
