Abstract Our daily electromagnetic environment is becoming increasingly complex with the rapid development of consumer electronics and wireless communication technologies, which in turn necessitates interference (EMI) shielding, especially for transparent components. We engineered a EMI shielding film crack-template based metallic mesh (CT-MM) that shows highly homogeneous light transmission strong microwave efficacy. The CT-MM fabricated using cost-effective lift-off method on crackle...

Microbially-synthesized protein-based materials are attractive replacements for petroleum-derived synthetic polymers. However, the high molecular weight, repetitiveness, and highly-biased amino acid composition of high-performance have restricted their production widespread use. Here we present a general strategy enhancing both strength toughness low-molecular-weight by fusing intrinsically-disordered mussel foot protein fragments to termini, thereby promoting end-to-end protein-protein...

Abstract Metallic mesh is a significant candidate of transparent conductive electrodes (TCEs) to substitute the current state‐of‐the‐art material indium tin oxide for optoelectronic devices. However, there remains challenge fabricate stable and good‐visibility metallic with low‐cost copper (Cu) material. A Cu electrode (on glass) high absolute transmittance ≈82% combined an adjustable low electrical resistance ≈0.2 Ω sq −1 total light reflectance 8.7% demonstrated here. The TCE shows...

The ability of amyloid proteins to form stable β-sheet nanofibrils has made them potential candidates for material innovation in nanotechnology. However, such a nanoscale feature rarely translated into attractive macroscopic properties mechanically demanding applications. Here, we present strategy by fusing peptides with flexible linkers from spidroin; the resulting polymeric can be biosynthesized using engineered microbes and wet-spun fibers. Using this strategy, fibers three different...

Wettability modification on a polymer surface is of immense importance for flexible electronics and biomedical applications. Herein, controlled wettability styrene-based shape memory has been realized by introducing micro-cracks the first time. The cracks were purposely prepared thin metal film constrained deformation polymer. After removal metallic film, was dramatically enhanced showing remarkable reduction in contact angle with water droplets from 85° to 25°. Subsequent systematic...

Sustainable aqueous zinc ion batteries (AZIBs) necessitate a wide operational temperature range to ensure practicability, yet achieving this often compromises either reaction kinetics at low temperatures or cycling stability high temperatures. Here we present an electrolyte design that balances trade‐off, enhancing the and of AZIBs across −60 60 °C. Our approach incorporates silk fibroin as multifunctional additive into ZnCl2‐based “water‐in‐salt” electrolyte, which modifies both structure...
