Special Issue Information

tDear Colleagues and Friends,

The Special Issue, “Aerogels – Synthesis, Characterization and Application”, will focus on the specific development of aerogels and aerogel based composites for advanced applications. Due to the outstanding combination of properties an awesome variety of applications using aerogels and aerogel based composites is possible. Applications requiring materials for thermal super insulation, light weight construction, electrochemical topics, acoustic damping, adsorption agents, medical issues, as well as cosmetics and personal care products to mention some are under development. All of them are dealing with special combinations of properties which are meanly defined by the open porous nanostructured network and the great variety of chemical origin of the aerogels. The requirements can be matched by a careful setting up, starting with lab-scale experiments followed by a smooth scaling-up and leading to industrial scale production in the near future. The idea of the special issue is to collect the knowledge of the correlation between the necessities of taking care on chemical precursors and reaction conditions during synthesis and suitable drying methods as well as further functionalization to meet the required combination of properties. In this context we would like to invite you to contribute to this special issue. Both original papers and reviews dealing with synthesis, characterization and prospective applications as well as numerical simulations on the design and functionality of aerogels and aerogel based composites are welcome.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Low density composites of sodium montmorillonite and poly(amide-imide) polymers have been created using an ice templating method, which serves as an alternative to the often-difficult foaming of high temperature/high performance polymers. The starting polymer was received in the poly(amic acid) form which can be cured using heat, into a water insoluble amide-imide copolymer. The resulting materials have densities in the 0.05 g/cm3 range and have excellent mechanical properties. Using a tertiary amine as a processing aid provides for lower viscosity and allows more concentrated polymer solutions to be used. The concentration of the amine relative to the acid groups on the polymer backbone has been found to cause significant difference in the mechanical properties of the dried materials. The synthesis and characterization of low density versions of two poly(amide-imide) polymers and their composites with sodium montmorillonite clay are discussed in the present work. Full article

Properties of an SiO2 aerogel-based rendering and its application on buildings

Some hygro-thermal properties of a commercially available aerogel-based rendering and its main ingredient have been investigated with respect to water respectively moisture uptake under different conditions in laboratory and on-site of different buildings. It was shown that water does not enter the aerogel granules but rather concentrates in the porous phase surrounding the granules. An application to a historic building without reinforcement mesh and structured finish, showed the versatile character of the render. Some infrared pictures show also the thermal influence of the aerogel-based rendering compared to the uninsulated façade.
