Aerogels, due to their unique features like lightweight, ultra-low thermal conductivity, and design variations, have gotten a lot of interest in thermal insulation, photocatalysis, and protective areas. Besides their superior thermal properties, aerogel thermal insulation and photocatalyst materials also possess many inherent flaws, such as handling issues, high manufacturing costs, and low strength as well as toughness. The most persuasive and successful ways to improve photocatalytic and thermal insulating qualities while lowering costs are composition optimization and microstructure reconstruction. Their high surface area and porosity make them ideal for enhancing the efficiency and capacity of these devices. Research may lead to more efficient and longer-lasting energy storage solutions. This review describes the characteristics, microstructural reconstruction, design variation, and properties of all aerogel fabrication techniques and provides a comprehensive overview of scientific achievements linked to them. The effectiveness of raw material compositions, properties, and mechanical parameters are also discussed. The major goal of this review is to highlight the aerogel-based materials and design variations and to explore the most potential development trends for photocatalysis and thermal applications. The industrial as well as technical applications of silica aerogels are also highlighted. This review highlights futuristic applications of aerogel-based textile materials to alleviate the CO2 burden on our atmosphere, either by providing next-level thermal insulation or by employing them in CO2 mitigating technologies such as CO2 capture.

This review explores the field of hybrid materials in the context of bio-based aerogels for the development of sustainable packaging solutions. Increasing global concern over environmental degradation and the growing demand for environmentally friendly alternatives to conventional packaging materials have led to a growing interest in the synthesis and application of bio-based aerogels. These aerogels, which are derived from renewable resources such as biopolymers and biomass, have unique properties such as a lightweight structure, excellent thermal insulation, and biodegradability. The manuscript addresses the innovative integration of bio-based aerogels with various other materials such as nanoparticles, polymers, and additives to improve their mechanical, barrier, and functional properties for packaging applications. It critically analyzes recent advances in hybridization strategies and highlights their impact on the overall performance and sustainability of packaging materials. In addition, the article identifies the key challenges and future prospects associated with the development and commercialization of hybrid bio-based aerogel packaging materials. The synthesis of this knowledge is intended to contribute to ongoing efforts to create environmentally friendly alternatives that address the current problems associated with conventional packaging while promoting a deeper understanding of the potential of hybrid materials for sustainable packaging solutions.

Skeletal elements of living organisms (bones, teeth, horns, frustules of diatomic algae, mollusk shells, sea urchin needles, and sponge spicules) are biogenic composite materials consisting of an inorganic part (calcium phosphate and carbonate, silica) and various organic compounds. The first step in the synthesis of these materials is the condensation of an inorganic precursor under the control of biopolymers capable of interacting with the growing inorganic particle. We studied formation of calcium carbonate in the presence of copolymers of acrylic acid, 1‐vinylimidazole and vinylamine. Some of the copolymers were new, so their acid–base properties were characterized. The polymers have an influence on the precipitation of CaCO3 in aqueous medium, and depending on the polymer structure and the polymer‐calcium ratio, composite precipitates or stable dispersions were obtained. Composite nanoparticles have a negative charge, and they can interact with polymer bases to form calcium‐organic composite materials. Calcium carbonate formation under the control of organic polymers is a chemical model of calcium skeletal growth in living nature. The resulting composites containing micrometer‐range CaCO3 particles are promising materials for the design of microstructured coatings with a high surface density of functional groups. Some of the polymers studied are not involved in the resulting material, but affect the morphology of CaCO3, forming particles in the micrometer range, which are promising as fillers for plastics.
