Abstract:In this study， polymerizable deep eutectic solvents （PDES） synthesized from acrylic acid and choline chloride was combined with cellulose nanofibril （CNF） aerogels by UV-initiated in situ polymerization， and phytic acid was introduced to enhance the bonding between CNF and PDES. The ionic conductive elastomers containing abundant covalent bonds and non-covalent bonds （hydrogen bonds） were prepared， and their properties were tested by a variety of modern instruments. The results showed that the ionic conductive elastomers had obvious advantages in mechanical properties （stress of 0.38 MPa and strain of 1378%）， thermal stability， frost resistance， ionic conductivity （ionic conductivity up to 3.9 mS/cm） and UV shielding， and had certain fatigue resistance and elasticity. And the flexible strain sensor based on the assembly showed rapid， stable and reversible signal responsed to human movement.
