Abstract
A stretchable, self-healing and deformable fiber has the potential to use in artificial intelligence products, such as implantable electronic devices, intelligent adaptive interface system and bionic robots. Advanced fibrous electronics with additional functions including bio-responsive, biocompatibility, and biological tissue reconfiguration remains a great challenge on advanced fiber engineering technology. Herein, we use functionalized single-walled carbon nanotubes (SWCNTs) and poly(sodium acrylate) (PAAS) to fabricate the multifunctional fiber through a hydrogel spinning process. The SWCNTs in fiber exhibit a uniaxial alignment under the fluid shear force in the microchannel. This fiber shows outstanding features: (i) elastic, extremely stretchable (could be stretched up to 1000%), and rapidly self-healing (93% healing efficiency within 5 min), (ii) Na+ ion responsive and deformable, and (iii) favoring nerve tissue reconfiguration.
