Next generation thermal insulators for operation in high-temperature and humid environments through aerogel carbonization

Abstract

We generated carbon aerogel with a high thermal stability and a wider operational range by carbonizing resorcinol-formaldehyde (RF) aerogels. The carbonization process was conducted using a gas mixture that consist...

Super-hydrophobic and resilient hybrid silica aerogels for thermal insulation, energy harvesting, and electrical applications in harsh environments

“…Furthermore, we conducted a fire retardancy test on the samples, assessing their performance in a vertical burning scenario, 48 as demonstrated in Fig. S5 (ESI †) for APH016.…”

Efficient Template-Catalyzed In Situ Polymerization for Carbon Xerogels with Large Specific Surface Area and High Adsorption

“…Alshrah et al prepared CXs with high thermal stability and a wider operating range using resorcinol-formaldehyde (RF) xerogel. 10 Jia et al prepared CXs with a hierarchical pore structure using linear phenolic resin and hexamethylenetetramine (HMTA), and the internal structure could be adjusted by adjusting the agent content. 11 Gao et al prepared RF-based CXs with graphitic crystallite nanomaterials as a catalyst, and the resulting CXs show high compressive strength and electrical conductivity.…”

“…Phenolic resin organic xerogels are the most promising candidate because the pore structure and properties can be controlled by adjusting the reaction conditions, raw materials, catalysts, solvents, and template agents. Alshrah et al prepared CXs with high thermal stability and a wider operating range using resorcinol-formaldehyde (RF) xerogel . Jia et al prepared CXs with a hierarchical pore structure using linear phenolic resin and hexamethylenetetramine (HMTA), and the internal structure could be adjusted by adjusting the agent content .…”
