Inspired by mussel adhesive polydopamine (PDA), effective reinforcement of graphene-based liquid crystalline fibers to attain high mechanical and electrical properties simultaneously is presented. The two-step defect engineering, relying on bioinspired surface polymerization and subsequent solution infiltration of PDA, addresses the intrinsic limitation of graphene fibers arising from the folding and wrinkling of graphene layers during the fiber-spinning process. For a clear understanding of the mechanism of PDA-induced defect engineering, interfacial adhesion between graphene oxide sheets is straightforwardly analyzed by the atomic force microscopy pull-off test. Subsequently, PDA could be converted into an N-doped graphitic layer within the fiber structure by a mild thermal treatment such that mechanically strong fibers could be obtained without sacrificing electrical conductivity. Bioinspired graphene-based fiber holds great promise for a wide range of applications, including flexible electronics, multifunctional textiles, and wearable sensors.

Indium tin oxide (ITO) is a broadly deployed transparent conductive electrode (TCE) with various applications in solar energy harvesting and optoelectronics. However, the low transmittance of ITO in the ultraviolet range has motivated researchers to opt for alternative materials as TCE. In this paper, the fabrication of a hybrid TCE made up of silver nanowire (AgNW) and peroxo-constructed amorphous strontium stannate (pcaSS) is reported, employing facile spin coating solution-processed method at 150 C. The fabricated TCE demonstrated low sheet resistance of 32.8 Ω sq À1 and high transmittance of 88.2% at 550 nm. Furthermore, benefitting from the ultrahigh band gap of as-synthesized pcaSS (4.5 eV), this TCE maintained its high transmittance (above 80%) inside ultraviolet range down to wavelength of 250 nm. This research contributes to the fabrication of more efficient solar energy and ultraviolet optoelectronic devices.Indium tin oxide (ITO) has been commercialized as a transparent conductive electrode (TCE) with various applications in solar cells, LEDs, and touch screens, to name a few. Nevertheless, the scarcity of indium has necessitated the replacement of ITO with alternative thin films. [1,2] Furthermore, the low transmittance of ITO within ultraviolet region restricts its application in ultraviolet optoelectronics due to inter-band absorption and light scattering by free electrons. [3,4] Numerous alternatives for ITO have proved propitious, including carbonaceous materials, [5][6][7] aluminum doped zinc oxide (AZO), [8,9] fluorine doped tin oxide (FTO), [10,11] and metal nanowire network.

Biostable electronic materials that can maintain their super mechanical and conductive properties, even when exposed to biofluids, are the fundamental basis for designing reliable bioelectronic devices. Herein, cellulose-derived conductive 2D bio-nanosheets as electronic base materials are developed and assembled into a conductive hydrogel with ultra-high biostability, capable of surviving in harsh physiological environments. The bio-nanosheets are synthesized by guiding the in situ regeneration of cellulose crystal into a 2D planar structure using the polydopamine-reduced-graphene oxide as supporting templates. The nanosheet-assembled hydrogel exhibits stable electrical and mechanical performances after undergoing aqueous immersion and in vivo implantation. Thus, the hydrogel-based bioelectronic devices are able to conformally integrate with the human body and stably record electrophysiological signals. Owing to its tissue affinity, the hydrogel further serves as an "E-skin," which employs electrotherapy to aid in the faster healing of chronic wounds in diabetic mice through transcutaneous electrical stimulation. The nanosheet-assembled biostable, conductive, flexible, and cell/tissue affinitive hydrogel lays a foundation for designing electronically and mechanically reliable bioelectronic devices.
