A new method for preparing tannin-based foams

The authors present a novel method for the preparation of highly porous tannin-based meringues by shear mechanical mixing of tannin, hexamine, and Kolliphore® ELP in water. The liquid foam was then cured in an oven at 85oC for 24 hours. The resultant solid foams were found ...

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 ...

Preparation and characterization of ultralow density silica aerogels by acetonitrile supercritical drying

In this study, ultralow density silica aerogels were synthesized and their thermal conductivities were tested to determine how supercritical drying affected the samples. A thermal analyzer measured the thermal conductivity of the silica aerogels using the transient plane source (TPS) method which determined that the ...

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 ...
