Systematic studies of tannin–formaldehyde aerogels: preparation and properties

A variety of tannin-formaldehyde aerogels were produced in order to examine the effects of pH and dilution during their manufacture. The authors produced a phase diagram that could describe them. Extensive physical property characterization was performed on the sample aerogels, including porosity, thermal conductivity, volume ...

Engineering thermal and mechanical properties of flexible fiber-reinforced aerogel composites

The authors present a method of fiber-reinforced aerogel composites by impregnation of four layers of aligned glass fibers into silica sol layer-by-layer. The effect of different fiber alignments, as well as the effect of fiber lamination on the mechanical strength of the silica aerogel composites ...

Thermoelectric behavior of aerogels based on graphene and multi-walled carbon nanotube nanocomposites

This paper proposes conducting carbon aerogels, composed of graphene and multi-walled carbon nanotubes, as an option for a thermoelectric material. The researchers found that this combination of materials increased the electrical conductivity and the Seebeck coefficient due to bridging effects, and decreased the thermal conductivity ...

Investigation of transmittance and thermal conductivity properties of silica gels for application as transparent heat insulation materials

In this article the effectiveness of silica aerogels as a transparent heat insulation material (TIM) is studied.  They are a good candidate for this application as the amount of energy that they absorb and emit is adjustable. The effects of different treatments (hydrothermal and firing) ...

Reduction of shrinkage and brittleness for resorcinol-formaldehyde aerogels by means of a pH-controlled sol-gel process 

This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using a transient plane source (TPS) method. As the R:W increases so does the thermal conductivity, this is because ...
