Because structural color is fadeless and dye-free, structurally colored materials have attracted great attention in a wide variety of research fields. In this work, we report the use novel coloration strategy applied to fabrication colorful colloidal fibers. The nanostructured fibers with tunable colors were massively produced by electrospinning. Experimental results theoretical modeling reveal that homogeneous noniridescent electrospun are caused two phenomena: reflection due band gap...
As an important component of wearable and stretchable strain sensors, dual-mode sensors can respond to deformation via optical/electrical dual-signal changes, which have applications in human motion monitoring. However, realizing a fiber-shaped sensor that work stably real life remains challenge. Here, we design interactive fiber with both mechanochromic mechanoelectrical functions be applied variety different environments. The is produced by coating transparent elastic conductive layer onto...

We demonstrate a facile method for preparing novel nanoporous material with an isotropic, three-dimensionally continuous pore structure from polymeric bicontinuous microemulsion precursor, which consists of two immiscible homopolymers and the corresponding diblock copolymer. The protocol generation nanopores is selective cross-linking one domain subsequent removal other by solvent dissolution.
Structurally colored fibers were fabricated using different-sized polystyrene (PS) nanospheres via electrophoretic deposition on conductive carbon fiber surfaces. The reflective spectra corresponding to different colors taken by microzone and angle-resolved spectrometers from a single colloidal fiber. As confirmed structural analysis, the outer layer of core-shell consisted face-centered cubic (f.c.c.) domains without long-range order. It is revealed that absence order in assembly caused...

Abstract Microsphere‐assisted optical imaging has been proved straightforward and cost‐effective for super‐resolution in material science biomedical research. Optically transparent microspheres with a high refractive index are critical achieving superior capabilities yet remain to be further exploited.
