[Adv. Mater. Interfaces] 3D Graphene Oxide Micropatterns Achieved by Roller-Assisted Microcontact Printing Induced Interface Integral Peel and Transfer
Most fascinating
applications of graphene based devices are highly depended on the precise
fabrication of patterned graphene microstructures. While considerable progress
of two-dimensional (2D) patterning of graphene has been achieved with various lithographic
techniques, the realization of patterned three-dimensional (3D) graphene
microstructures still remains a significant challenge. Here, we re...

[Adv. Funct. Mater.] A multi-responsive anisotropic hydrogel with macroscopic three-dimensional complex deformations
As one of the most
promising smart materials, stimuli-responsive polymer hydrogels (SPHs) can
reversibly change the volume or shapes in response to external stimuli, they
thus have shown promising applications in many fields. While considerable progress
of two-dimensional (2D) deformation of SPHs has been achieved, the realization
of three-dimensional (3D) or even more complex deformation still re...

[Adv. Mater.] Two-Dimensional Protein Supramolecular Nanofilm with Exceptionally Large Area and Emergent Functions
The development of versatile materials and engineering devices requires multifunctional conformal coatings that gains increasing interests. However, few methods can achieve a stable, large-area and colorless coating on substrates with different structure, composition and shapes. We report the one-step aqueous coating of virtually arbitrary material surfaces using self-assembled macroscopic biona...

[Adv. Mater. Interfaces] Highly Efficient Actuator of Graphene/Polydopamine Uniform Composite Thin Film Driven by Moisture Gradients
Bilayer materials with different swelling behavior are usually used as actuator, yet still suffer from limitations such as poor
interlayer adhesion during frequent bending, and the complex multistep fabrication process. Here, we present a new
strategy that a structure of reduced graphene oxide/polydopamine (RGO-PDA) uniform
composite thin film can serve as highly efficient actuator driven by moist...

[Adv. Mater.] A Superhydrophobic Surface Templated by Protein Self-Assembly and Emerging Application toward Protein Crystallization
Superhydrophobic surfaces have demonstrated their great values in modern material science. As a result, the preparation of such a surface is continuously appealing to academics and industries. Conventional material sources to construct a superhydrophobic surface include synthetic organic/inorganic and metal substances. Herein, we reported a new type of material source as natural protein capable ...

[Adv. Mater. Interfaces] Simple Multipurpose Surface Functionalization by Phase Transited Protein Adhesion
Engineered surface modification is of prime importance in modern material science. This work reports how to manipulate a surface property towards ultra-performance, multi-functionalities, and smartness/responsiveness by utilizing newly-discovered lysozyme phase transition. The phase-transited lysozyme product consisting of amyloid-contained microfiber network could stabl...

[Sci. Adv. Mater.] Preparation and Surface Morphology Control of Self-assembled graphene oxide/chitosan Composite Membrane
Graphene oxide (GO)/chitosan composite membrane with thickness of several hundred nanometers was prepared through self-assembly at the air-liquid interface. Thermogravimetric analysis (TGA), Fourier transform infrared (FTIR) spectra and X-ray photoelectron spectroscopy (XPS) were employed to study the interactions that induced the assembly of GO nanosheets and chitosan. The results show that the m...

(Adv. Funct. Mater.) Bio-inspired Heterostructured Fibers with Bead-on-String to Respond the Environmental Wetting
Inspired by the geometric structure of ecribellate spider capture silk and its spinning characteristics, we propose a one-step electrohydrodynamic method to fabricate bead-on-string heterostructured fi bers (BSHFs). By combining electrospinning and electrospraying strategies using a sprayable outer fluid with low viscosity and a spinnable inner fl uid with high viscosity in a coaxial jetting proce...

(Adv. Mater.) Direction Controlled Driving of Tiny Water Drops on Bio-inspired Artificial Spider Silks
Inspired by the spider silk, we fabricated a series of artifi cial spider silks with spindle-knots in which the chemical compositions and surface nanostructures were subtly designed. Our investigations demonstrated that tiny water drops (tens of picoliters) could be driven with controllable direction (“toward” or “away from” the knot) by optimizing the cooperation of curvat...

(Adv. Mater.) Controlled Fabrication and Water Collection Ability of Bioinspired Artificial Spider Silks
We show that the “spindle-knots/joints” structures can only be fabricated under an optimized condition and the size of the spindle-knots is tuned to investigate its effect on the water collection ability of BASs. In our method (see Experimental Section and Supporting Information, Figure S1), a uniform nylon fi ber is fi rstly immersed into a
polymer solution, poly(methyl methacrylate)...
