Recycled Paper Cellulose Aerogel Synthesis and Water Absorption Properties

Abstract:

By applying sodium hydroxide/urea and a sample freeze drying method, we successfully synthesized green cellulose aerogel from paper waste for the first time. We adjusted the cellulose concentration from 1.5 percents to 4 percents in the initial hydrogel. They yielded densities changing from 0.03-0.1 g/cm³.The absorption capacities varied from 9 to 20 times of their own weight. To investigate the water absorption capacity in relationship with the initial chemical dosage, we changed the input amount of urea and sodium hydroxide, which is the first study ever. The thermal conductivity of the 2 percents sample ranged from 0.029-0.032 W/mK. Besides, the material has a high potential to be used in diaper industry as it is biodegradable which is better than most super absorbent polymers.
