Production of porous cellulose aerogel fibers by an extrusion proces

This study outlines the preparation method and properties of thin extruded cellulose aerogel fibers and monolithic pieces. Microcrystalline cellulose was combined with a hydrated calciumthiocyanate salt melt to form a gel at 80˚C. In order to obtain fine, homogenous, wet cellulose filaments, twin screw extrusion experiments were performed. Cellulose aerogel filaments were yielded once the gels were washed and coagulated in an ethanol solution, and had undergone supercritical drying with ...

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 ...
