Core Shell Structure

The spherical cellulose aerogels with core-shell structure were prepared through hanging drop method in a regenerated non-polar solution. The procedures of these aerogels' preparation include solidification in the acetic acid solution to form a hydrogel, solvent exchange with t-butyl alcohol and freeze drying. The spherical cellulose aerogels were obtained with different cellulose solution concentration, and characterized with BET analysis and electron microscopy. Their density and porosity varied linearly with different cellulose content in the initial solution. And the gel shrinkage upon drying was limited to, on average, 7.3%. The density of spherical cellulose aerogel could be reached down to 0.14 g·cm-3 with high specific surface areas up to 210 m2·g-1. The mesopores' diameter of spherical cellulose aerogel at the highest peak in the size distribution curve is focus on 15nm.

Current Trends

Cellulose-based aerogels hold the potential to become a cost-effective bio-based solution for thermal insulation in buildings. Low thermal conductivities (<0.025 W·m−1·K−1) are achieved through a decrease in gaseous phase contribution, exploiting the Knudsen effect. However, several challenges need to be overcome: production energy demand and cost, moisture sensitivity, flammability, and thermal stability. Herein, a description and discussion of current trends and challenges in cellulose aerogel research for thermal insulation are presented, gathered from studies reported within the last five years. The text is divided into three main sections: (i) an overview of thermal performance of cellulose aerogels, (ii) an identification of challenges and possible solutions for cellulose aerogel thermal insulation, and (iii) a brief description of cellulose/silica aerogels.
