Gas Permeability of Cellulose Aerogels with a Designed Dual Pore Space System.

ABSTRACT: The gas permeability of a porous material is a key property determining the impact of the material in an application such as filter/separation techniques. In the present study, aerogels of cellulose scaffolds were designed with a dual pore space system consisting of macropores with cell walls composing of mesopores and a nanofibrillar network. The gas permeability properties of these dual porous materials were compared with classical cellulose aerogels. Emulsifying the oil droplets in the hot salt-hydrate melt with a fixed amount of cellulose was performed in the presence of surfactants. The surfactants varied in physical, chemical and structural properties and a range of hydrophilic-lipophilic balance (HLB) values, 13.5 to 18. A wide range of hierarchical dual pore space systems were prod
