Castor oil-based waterborne polyurethane/tunicate cellulose nanocrystals nanocomposites for wearable strain sensors

Recent advances in cellulose nanocrystals-based sensors: a review

“…10 shows the use of CNCs in physical sensing, Fig. 10(a) shows PU/tCNCs based wearable sensors and their working mechanism, 201 Fig. 10(b) shows CNCs/PNIPAM based multi-responsive hydrogels, 202 Fig.…”

“…In a study reported by Deng et al , 201 TCNCs were mixed with castor oil-based waterborne polyurethane (WPU) using a straightforward solution blending technique to create bio-based nanocomposites. The impact of TCNCs on the particle size and stability of composite dispersions and the thermophysical and mechanical properties of composite films was investigated and discussed.…”

Ultra-robust, Highly Stretchable, and Conductive Nanocomposites with Self-healable Asymmetric Structures Prepared by a Simple Green Method

“…Jin et al dissolved poly­(vinylidene difluoride) (PVDF) into a mixture of acetone and dimethylformamide, formed PVDF NFs through electrostatic spinning, embedded Ag flakes and PVDF NFs into fluorine elastomers, and dried in an 80 °C oven for 2 h to produce a highly durable nanofiber-reinforced elastic conductor . Deng et al mixed TCNCs with castor oil-based waterborne polyurethane (WPU) to prepare nanocomposite films by repeatedly casting AgNW suspensions on the surface of composite films and drying them at 50 °C until a uniform AgNW is formed on the surface of the films, and a flexible strain sensor is produced . Although good work has been done, most conductive composites require complex preparation processes and volatilization of organic solvents.…”

“…43 Deng et al mixed TCNCs with castor oil-based waterborne polyurethane (WPU) to prepare nanocomposite films by repeatedly casting AgNW suspensions on the surface of composite films and drying them at 50 °C until a uniform AgNW is formed on the surface of the films, and a flexible strain sensor is produced. 44 Although good work has been done, most conductive composites require complex preparation processes and volatilization of organic solvents. Therefore, it remains a great challenge to prepare nanocomposites with high conductivity and stretchability through simple, green, scalable methods.…”
