“…This multiscale approach involves first estimating the e↵ective properties of the tows from the fibre and matrix properties and then predicting the lamina properties from the properties of the tows and the matrix. This methodology was implemented using the software TexGen4SC [41,42]. Each lamina is composed of a polyester resin matrix (AROPOL FS 1963 with MEKP-50 hardener) reinforced with a bi-axial E-glass plain weave fabric (EC9 68×2).…”

“…Currently, the literature on BaTiO 3 -based materials predominantly focuses on 1D and 2D materials rather than 3D aerogel materials. Despite the exceptional potential of aerogel materials in adsorption and photocatalysis due to their unique surface area and abundant pore structure [ 19 , 20 , 21 ], the synthesis of BaTiO 3 aerogel remains a highly intricate challenge that has yet to be fully resolved [ 18 , 22 ]. Chau et al [ 18 ] employed chitin nanocrystals as a liquid crystal template for the synthesis of BaTiO 3 aerogel.…”

Given the increasingly severe environmental problems caused by water pollution, the degradation of organic dyes can be effectively achieved through the utilization of photocatalysis. In this work, metal alkoxides and a combination of alcohol/hydrophobic solvents are employed to prepare BaTiO3 aerogels via a liquid-phase and template-free synthetic route. The preparation process of the aerogels solely entails facile agitation and supercritical drying, eliminating the need for additional heat treatment. The binary solvent of ethanol and toluene is identified as the optimal choice, resulting in a significantly enhanced surface area (up to 223 m2/g) and an abundant pore structure of BaTiO3 aerogels compared to that of the BaTiO3 nanoparticles. Thus, the removal efficiency of the BaTiO3 aerogel sample for MO is nearly twice as high as that of the BaTiO3 nanoparticles sample. Noble metal Ag nanoparticles’ deposition onto the BaTiO3 aerogel surface is further achieved via the photochemical deposition method, which enhances the capture of photogenerated electrons, thereby ensuring an elevated level of photocatalytic efficiency. As a result, Ag nanoparticles deposited on BaTiO3 aerogel can degrade MO completely after 40 min of illumination, while the corresponding aerogel before modification can only remove 80% of MO after 60 min. The present work not only complements the preparatory investigation of intricate aerogels but also offers a fresh perspective for the development of diverse perovskite aerogels with broad applications.
