Special Issue Information

Dear Colleague,

Aerogels are the lightest solid-state substances with extremely low density, a very high surface area, and exhibit an open mesopore system. A continuously growing family of aerogel-based materials are aerogel composites and nanocomposites, in which the aerogel phase serves as a matrix. Interaction between the matrix and guest particles may improve certain properties and lead to the appearance of new ones. Molecular level distribution of at least two matrix components creates aerogel hybrids. Chemical modifications and structural reinforcement may lead to unique mechanical, optical, catalytic and surface properties. Aerogel composites and aerogel hybrids are being extensively studied and used in a variety of areas, such as insulation, rechargeable batteries, chemical sensors, catalysts, drug delivery, and tissue engineering.

This Special Issue “Aerogel Composites, Nanocomposites, Hybrids, and their Applications” focuses on any aspects of synthesis, production, structure, and properties of aerogel composites, with particular attention given to the interaction between matrix components and guest particles that may result in an enhancement of certain properties.

Both original papers and reviews dealing with the synthesis, properties, and applications of aerogel composites, nanocomposites and hybrids are welcome.

In recent years, flexible silica aerogels have gained significant attention, owing to their excellent thermal and acoustic insulation properties accompanied by mechanical flexibility. Fiber reinforcement of such aerogels results in a further enhancement of the strength and durability of the composite, while retaining the excellent insulation properties. In this paper, the influence of four different kinds of fibers within a flexible silica aerogel matrix is studied and reported. First, a description of the synthesis procedure and the resulting morphology of the four aerogel composites is presented. Their mechanical behavior under uniaxial quasi-static tension and compression is investigated, particularly their performance under uniaxial compression at different temperature conditions (50 °C, 0 °C, and −50 °C). The reinforcement of the flexible silica aerogels with four different fiber types only marginally influences the thermal conductivity but strongly enhances their mechanical properties. Full article
