High-electrical-resistivity thermally-conductive phase change materials prepared by adding nanographitic fillers into paraffin

Author(s): , , , , ,

Pristine and modified exfoliated graphite nanoplatelets (xGnPs and M-xGnPs, respectively) were dispersed into a paraffin wax phase change material (PCM) in an effort to raise the thermal conductivity of the ...

Influence of thermal process on microstructural and physical properties of ambient pressure dried hydrophobic silica aerogel monoliths

Author(s): , , , , , , ,

Ambient pressure dried hydrophobic silica aerogel monoliths were prepared via simultaneous solvent exchange and surface modification in order to minimize volume shrinkage and density. At room temperature, the obtained silica ...

Synthesis and characterization of silica aerogel and its composite materials

Author(s): , ,

Composite silica aerogels were prepared using sodium silicate and ceramics fibers. The thermal conductivities of these composites were investigated to determine how effective they would be as thermal insulation. As ...

Preparation and Characterization of Ultralow Density Silica Aerogels by Acetonitrile Supercritical Drying

Author(s): , , ,

Ultralow density silica aerogels were formulated by sol-gel process using tetramethyl orthosilicate as the precursor. A supercritical drying step was performed using acetonitrile solvent extraction. These aerogels were found to ...

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

Author(s): , , , , ,

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 ...
