Aeropectin: Fully Biomass-Based Mechanically Strong and Thermal Superinsulating Aerogel

Abstract : Monolithic pectin aerogels, aeropectins, were prepared via dissolution gelation coagulation and subsequent drying with supercritical CO2. Aeropectin had pore sizes that varied from mesopores to small macropores and compression moduli in the range from 4 to 18 MPa. Aeropectins show plastic deformation up to 60% strain before the pore walls collapse. Pectin aerogels have a thermal conductivity below that of air in ambient conditions, making them new thermal superinsulating fully biomass-based materials. The contribution of gas and solid conduction plus radiative heat transfer were determined and discussed.
