“…This could be explained by the higher viscosity of the PVDF‐SiO 2 solution compared to pure PVDF, yielding a substrate with thicker fibers thus with larger pore size (lower packing density) and higher porosity. [ 66,69,70 ] Electrospinning voltage also affects porosity as Tian et al [ 61 ] showed that PVDF electrospun at 27 kV has smaller pore sizes and higher porosity compared to PVDF electrospun at 30 kV which yields thicker fiber. The electrospun membranes generally have an open and porous structure which often explains their low structural parameters.…”

“…[ 73,74 ] Small pore sizes in electrospun substrates can be obtained with tiny fiber diameters and high packing densities. [ 69,70 ] While the presence of hydrophilic SiO 2 nanoparticles improved the support layer's wettability, it seems to be less significant in the IP process than the surface structure. This structure might not be adequate for the formation of a high‐selectivity PA layer.…”

This paper is a comparative study on the preparation techniques used to make the support layer of polyamide‐thin‐film composite forward osmosis (TFC‐FO) membranes. The role played by the support layer preparation technique in membrane performance is thoroughly investigated in this study. Electrospinning is shown to produce membranes of lower structural parameter compared to those obtained by conventional phase inversion techniques. The electrospun polyamide selective layer can also be tailored with the required properties. This makes electrospinning a promising process to design efficient FO membrane substrates. It is shown in this work that the FO water flux is more dependent on the internal structure of the support layer than the preparation materials. The main challenge remaining for substrates to operate in FO is to achieve simultaneously a low structural parameter, a high surface porosity, and the required mechanical properties. As most of today's approaches are not suitable, further materials development is essential in future investigations on TFC‐FO membranes.

Polymeric nanofibers have appeared as unique one-dimensional nanomaterials. Nanofibers possess exceptionally high specific surface area and essential properties. Various polymeric nanofibers and nanocomposite nanofibers have been developed using thermoplastic and thermosetting matrices and organic and inorganic nanoparticles. This review documents the worth of nanofiber technology regarding the synthesis, morphology, physical properties, and applications of the nanostructures. The nanofiber surface morphology and diameter directly influence the physical characteristics such as electrical conductivity, mechanical properties, and thermal stability. Fiber processing techniques and related parameters also affect their texture and properties. In this regard, electrospinning is frequently used to form polymeric nanofibers and nanocomposite nanofibers. Electrospun nanofibers having large surface area and excellent fiber orientation, alignment, and morphology. The polymer nanocomposites with different nanofillers (carbon nanotube, graphene, carbon nanofibers, and other nanoparticles) have been processed into high performance electrospun nanofibers. Electrospun nanomaterials have been applied in engineered structures, nanofibrous membranes, electronic devices, tissue engineering, drug delivery, antibacterial materials and other biomedical applications. Henceforth, this is a comprehensive review on physical characteristics, morphology, processing aspects, and application areas for polymeric and nanocomposite nanofibers.

This chapter's goal is to perform a review of the scientific literature that enables architects and urbanists to realize the importance of applying nanomaterials in their daily professional activities and, at once, be able to recognize the broad variety of nanomaterials and their applications in architecture, urbanism, and construction. To do so, it was necessary to review the scientific literature by means of the best search engines and scientific databases for such ends, which implies searching by main topics related to nanomaterials, energy, water, and foods in categorized, organized, and analyzed information according to such topics. It turned into reliable information mainly aimed at professionals in the areas of architecture, urbanism, and construction, focused on new materials and with an interest in finding out about various nanomaterials and their application in the urban-architectonic field of knowledge; it is also intended for scientists and academicians engaged in nanomaterials and nanotechnology with a number of
