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. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
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 the gels using the transient plane source (TPS) method. Results showed that, as expected, thermal conductivity increased with bulk density. Cryogels were found to be ...
In this study, the thermal properties of stainless steel, ceramic, and silica aerogels were numerically calculated and then compared to actual test results. A thermal constants analyser measured the thermal conductivities and thermal diffusivities of the samples using the transient plane source (TPS) method. Results showed that the values generated by the numerical simulation were within ±3% of the TPS method values, which verifies the reliability and accuracy of the numerical ...
The first soy and tannin based organic aerogels with 91% naturality have been developed by researchers, and they have low bulk density but high volumes of mesopores. In this experiment, the transient plane source (TPS) method was used to measure the thermal characteristics of the organic aerogels. Results showed that these novelty aerogels are ecologically friendly because they are low cost and renewable but have attractive thermal properties....
