Aerosol Route to Functional Nanostructured Inorganic and Hybrid Porous Materials

Abstract

The major advances in the field of the designed construction of hierarchically structured porous inorganic or hybrid materials wherein multiscale texturation is obtained via the combination of aerosol or spray processing with sol-gel chemistry, self-assembly and multiple templating are the topic of this review. The available materials span a very large set of structures and chemical compositions (silicates, aluminates, transition metal oxides, nanocomposites including metallic or chalcogenides nanoparticles, hybrid organic-inorganic, biohybrids). The resulting materials are manifested as powders or smart coatings via aerosol-directed writing combine the intrinsic physical and chemical properties of the inorganic or hybrid matrices with defined multiscale porous networks having a tunable pore size and connectivity, high surface area and accessibility. Indeed the combination of soft chemical routes and spray processing provides "a wind of change" in the field of "advanced materials". These strategies give birth to a promising family of innovative materials with many actual and future potential applications in various domains such as catalysis, sensing, photonic and microelectronic devices, nano-ionics and energy, functional coatings, biomaterials, multifunctional therapeutic carriers, and microfluidics, among others.

Scalable and Environmentally Benign Process for Smart Textile Nanofinishing

“…Here, we propose a sustainable and universal approach to textile nanofinishing that relies on a single-step NP synthesis and deposition process. Among the various aerosol processes, electrical discharges allow the high-yield synthesis of a wide range of well-defined NPs [20][21][22][23][24][25] (with respect to NP concentration, size, 26,27 crystallinity, 28 and chemical composition 29,30 ) that can be directly deposited onto textile fibers by diffusion, in a green and universal manner. The uniqueness of the proposed process lies in that diffusional deposition can be easily integrated into textile nanofinishing while providing a controlled loading profile within the textiles.…”

Porous polymer particles—A comprehensive guide to synthesis, characterization, functionalization and applications

“…The first one is called aerosol polymerization [237], which utilizes a gas, for instance air, as the continuous phase instead of a liquid. The interfacial tension between monomer droplets and the surrounding gas also renders the former spherical, such as in the case of rain droplets.…”
