Novel Al2O3-SiO2 composite aerogels with high specific surface area at elevated temperatures with different alumina/silica molar ratios prepared by a non-alkoxide sol-gel method

This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a transient plane heat source method....

Hybrid graphene aerogels/phase change material composites: Thermal conductivity, shape-stabilization and light-to-thermal energy storage

The use of graphene aerogel has recently been studied with highly functional phase change materials (PCMs) to create 3D structures for improved thermal conductivity and shape-stabilization. In this study, hybrid graphene aerogels (HGA) comprising graphene oxide (GO) and graphene nanoplatelets (GNP) were prepared. Thermal conductivity was measured and results found thermal conductivity increased linearly with low GNP content and continued to grow at a slower rate with increased GNP. Improvement ...

Effect of the thermal treatment on microstructure and physical properties of low-density and high transparency silica aerogels via acetonitrile supercritical drying

Silica aerogels have extremely low thermal conductivities, potentially making them effective thermal insulators. In this study, the thermal conductivities of various samples were explored using the Transient Plane Source (TPS) Method. Samples of the silica aerogels were approximately 1.3 cm thick and between 4.1-4.3 cm in diameter, and were tested at different temperatures. Results showed that as the temperature of the samples increased from 25-50 °C, thermal conductivity increased exponentially. As ...

Flame Retardant, Heat Insulating Cellulose Aerogels from Waste Cotton Fabrics by in Situ Formation of Magnesium Hydroxide Nanoparticles in Cellulose Gel Nanostructures

Aerogels are promising thermal insulators because of their low thermal conductivity, durability and eco-friendly nature. However, aerogels become a problem because of their highly flammable properties. In this study, flame retardant cellulose insulators were formed from scrap pieces of cotton. Firstly, an NaOH/Urea solution was combined with the scrap pieces of cotton to create a nanoporous three-dimensional cellulose gel. This gel will ultimately serve as a template for the ...

Assembly of silica aerogels within silica nanofibers: towards a super-insulating flexible hybrid aerogel membrane

Silica aerogels (SA) are identified as one of the most advanced thermal insulating materials to date, however, their range of applications is limited due to a high sensitivity to moisture and issues with brittleness. This study highlights the design and fabrication of a new and improved thermal insulation material, robust flexible hybrid silica nanofiber (SNF)-SA membranes. To allow for higher thermal insulating characteristics, these membranes form an interpenetrating network ...
