New tannin-lignin aerogels

Tannin and lignin are organic materials that are more cost-effective than synthetic, non-renewable phenolic compounds. In this paper, tannin-lignin-formaldehyde (TLF) composites were used to synthesize thermally insulative mesoporous aerogels. A thermal analyzer measured the thermal conductivity of two TLF samples using the transient plane source (...

Influence of environmental factors on the adsorption capacity and thermal conductivity of silica nano-porous materials 

Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. ...

Lignin-phenol-formaldehyde aerogels and cryogels

Lignin and phenol are inexpensive naturally derived resources that can be used to produce cost-effective organic gels. This paper aimed to examine the thermal properties of insulative organic aerogels and cryogels made from lignin and phenol. A thermal analyzer (TPS) measured the thermal conductivity of ...

Ambient pressure dried shape-controllable sodium silicate based composite silica aerogel monoliths

The preparation process of silica aerogels has commonly involved a dangerous supercritical drying step, so work has been done to eliminate this step. This paper discusses the preparation of composite silica aerogels containing silica fibers using a method that excludes the supercritical drying step. The ...

Tailoring the structure of cellular vitreous carbon foams

The authors set out to prepare cellular vitreous carbon (CVC) foams with varying thermal and physical properties. This was accomplished by using tannin-based resin modified by different isocyanates in varying amounts. Three different experimental procedures were used to prepare foams with different physical and thermal ...
