Chen, Ziyang published the artcileHydrophobic and thermal-insulating aerogels based on rigid cellulose nanocrystal and elastic rubber, Synthetic Route of 7575-23-7, the main research area is hydrophobic thermal insulating aerogel cellulose nanocrystal elastic rubber; Aerogels; Cellulose nanocrystals; Click reaction; Rubber.

Inspired from the ancient China philosophy of “”coupling hardness with softness””, we attempted the combination of rigid cellulose nanocrystals (CNC) and elastic rubbers to solve the limitations of structural brittleness and water sensitivity of CNC-based aerogels. Three rubber chains with the different chem. structures (silicon rubber, 1,2-polybutadiene, styreneic block copolymer) were covalently bonded on the CNC porous skeleton based on thiol-ene click chem., to fabricate the CNC/rubber composite aerogels. With the introduction of moderate loading levels of rubber, the composites aerogels exhibited low d. and shrinkage, high porosity and sp. surface area and improved mech. performance. Furthermore, the presence of rubber components completely changed the hydrophilic nature of cellulose skeleton as the hydrophobic aerogels, contributing the superior solvents resistance and self-cleaning property. With their advantages on mech. stability, heat insulation and hydrophobicity, the fabricated aerogels in this study exhibited the high added values in various potential applications.
