Article
Fibers have been widely used for wearable textiles and fiber-reinforced composites owing to their unique structures and performances. However, design and fabrication of 1D advanced fiber materials with diversified surface microstructures and desired functionalities is still a considerable challenge. In this study, we present a novel one-dimensional...
Article
One‐dimensional (1D) continuous advanced functional materials and devices with inherent flexibility for complex deformations facilitate a broad range of applications in wearable technology. This communication presents a new electrostatic self‐assembly strategy for controllable assembly of nanomaterials to fabricate 1D continuous materials with cust...
Article
Flexible piezoelectric nanogenerators (FPENGs) have attracted a great attention owing to their promising applications in harvesting mechanical energy and driving portable devices. To develop high-performance FPENGs, the significant relationship among material, structure and performance inspired us a rational design of FPENGs from Pdop-BaTiO3@P(VDF-...
Article
Conventional use of textiles as substrates for incorporation of brick materials (i.e. polymers and nanomaterials) is ubiquitously developed with primary purposes for introducing desired technical/functional performance rather than maintaining the aesthetic/decorative characteristics and inherent advantages (i.e. flexibility and permeability) of tex...

Viscoelastic polymer adhesives (VPAs) are common materials broadly used in adhesive tapes for bonding objects tightly in daily life. This work presents a conceptually new strategy of using contact electrification (rather than strong adhesion) of VPAs to directly convert mechanical energy to electric energy, generally showing 202-419% of the electri...
Article
Fiber material is composed of a group of flexible fibers that are assembled in a certain dimensionality. With its good flexibility, high porosity and large surface area, it demonstrates a great potential in development of flexible and wearable electronics. In this work, a kind of nickel/active material coated flexible fiber (NMF) electrodes, such a...

Three-dimensionally conformal porous microstructured fabrics (3CPMFs) are a new kind of modified fabrics with three-dimensionally conformal porous microstructures of introduced materials recently developed for wearable technology. They can effectively introduce customized functional performance based on the choice of brick materials, while at the s...

Rapid advances in functional electronics bring tremendous demands on innovation toward effective designs of device structures. Yarn supercapacitors (SCs) show advantages of flexibility, knittability, and small size, and can be integrated into various electronic devices with low cost and high efficiency for energy storage. In this work, functionaliz...

Breath figures (BFs) are a kind of water droplet arrays that can be formed by condensing aqueous vapor onto a cold surface, such as dewy phenomenon on a spider web. This study developed a BF-inspired approach for direct introduction of desired materials onto the textile surfaces with three-dimensionally conformal porous microstructures by the evapo...
Article
Triboelectric nanogenerator (TENG) is an innovative kind of energy harvester recently developed based on organic materials for converting mechanical energy into electricity through the conjunction use of triboelectric effect and electrostatic induction. Polymeric materials and their microstructures play key roles in the generation, accumulation, an...
Article
The intense interest surrounding asymmetrical microparticles originates from their unique anisotropic properties and promising applications. In this work, direct self-assembly of polymeric microspherical caps without the assistance of any additives has been achieved by using low-surface-tension methanol (MeOH) and high-surface-tension water as bina...
Article
An aramid-assisted acid spinning strategy was developed for rapid fabrication of continuous macroscopic multi-walled carbon nanotube (MWCNT) fibers by dispersing MWCNTs and Kevlar into most widely used concentrated sulfuric acid (>95%). The resultant fibers comprising over 85 wt% MWCNTs had a high strain rate of approximately 11.90%, and held enoug...

Full-text available
A robust asphalt-assisted breath figure templating approach has been developed for general fabrication of ordered porous polymer films and functional hybrid films with hierarchical microstructures. The incorporation of desired non-polymeric components, such as titanium dioxide nanoparticles and silver nanowires, shows little influence on the regula...

A silicon-containing graft copolymer, poly(dimethylsiloxane)-graft-polyacrylates, was explored as single-source precursor for the preparation of silicon oxycarbide (SiOC) with honeycomb microstructures by a novel reliable approach composed of breath figure (BF) process, plasma modification and pyrolysis. Multilayer ordered porous films prepared by...
Article
Polymeric films with nanoscale networks were prepared by selectively swelling an amphiphilic diblock copolymer, polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP), with the CO(2)-expanded liquid (CXL), CO(2)-methanol. The phase behavior of the CO(2)-methanol system was investigated by both theoretical calculation and experiments, revealing that me...
Article
In Qiao's previous report, only star polymers with T(g) (glass transition temperature) below 48°C were found forming homogeneous honeycomb coatings on the nonplanar substrates. The polymers with high T(g) are believed not able to duplicate nonplanar substrate due to their brittleness. This article presents a comprehensive study on the construction...

In this paper, highly ordered honeycomb polymeric films were prepared via a static breath-figure process under methanol atmosphere for the first time. The employed block copolymer, poly (dimethylsiloxane)-block-polystyrene (PDMS-b-PS), was synthesized by atom transfer radical polymerization. The influences of vapor atmosphere and the concentration...

Multi-level carbon nanotube (CNT) arrays with adjustable patterns were prepared by a combination of the breath figure (BF) process and chemical vapor deposition. Polystyrene-b-poly(acrylic acid)/ferrocene was dissolved in carbon disulfide and cast onto a Si substrate covered with a transmission electron microscope grid in saturated relative humidit...

Here, we present the preparation of thermally stable and solvent resistant micro-patterned polymeric films via static breath-figure process and sequent vulcanization, with a commercially available triblock polymer, polystyrene-b-polyisoprene-b-polystyrene (SIS). The vulcanized honeycomb structured SIS films became self-supported and resistant to a...

We describe a facile method to micropattern solid substrates: breath figure lithography (BFL). A honeycomb structured gold mask was prepared by sputter-coating a micro-porous polymer film with BF arrays, and then inductively coupled plasma reactive ion etching (ICP-RIE) transferred the patterns onto silicon wafer. The large etching rate selectivity...
