High-Performance Light-Emitting Diodes Encapsulated with Silica-Filled Epoxy Materials
Packaging materials have a great impact on the performance and reliability of light-emitting diodes (LEDs). A set of evaluation methods have been established to characterize the reliability of LED devices. No delamination or internal cracking between packaging materials and lead frames has been found for the encapsulated high performance LED devices after the package saturation with mo...

182. Nitrogen-doped graphene hollow nanospheres as novel electrode materials for supercapacitor applications.
Nitrogen-doped graphene hollow spheres (NGHS) have been prepared by a simple layer-by-layer assembly of graphene oxide (GO) and polyaniline (PANI) on polystyrene (PS) nanospheres, followed by calcination to remove the PS template and realize the carbonization of PANI. The resultant NGHS has a high nitrogen content of 8.7 atom%, in which various nitrogen species, such as pyridinic-N, pyrrolic-N, an...

Skin tissue repair materials from bacterial cellulose by a multilayer fermentation method
Using an improved method, the multilayer fermentation method, bacterial cellulose (BC) was produced by Gluconacetobacter xylinus. The structure and morphology were analysed by an electronic microscope. The surface area and tensile strength were characterised. In vitro, the cytotoxicity of BC was determined by the proliferation, adhesion property, morphology, and viability of human adipose-derived ...

Cellulose-based solid-solid phase change materials synthesized in ionic liquid
A series of cellulose graft poly(ethylene glycol) (cellulose-graft-PEG) copolymers as phase change materials (PCMs) were synthesized in ionic liquid by using 4, 4-diphenylmethane diisocyanate as coupling reagent. FTIR and H-1 NMR characterized the structure of the copolymers. Differential scanning calorimetry (DSC) indicated that the copolymers showed phase transitions with large thermal stor...

Polyamide 11/Poly(vinylidene fluoride) Blends as Novel Flexible Materials for Capacitors
A novel capacitor with high dielectric constant (e) has been developed by blending poly-(vinylidene fluoride) (PVDF) with polyamide (PA11). The blends show high dielectric constants (eblend¼40), which give better frequency stability (1 MHz), and excellent mechanical properties. Based on certain volume fractions, the measured dielectric constants (eblend) were found to exceed those of...

Front. Chem. China, 2010, 5, 247-261. Bioinspired synthesis and preparation of multilevel micro/nanostructured materials
In this review, some living organisms with multilevel hierarchical micro/nanostructures and related special properties are briefly introduced. The unique properties of organisms are mostly related to their special hierarchical micro/nanostructures. Inspired by nature, many zero-dimensional and one-dimensional micro/nanomaterials with biomimic or bioinspired multilevel micro/nanostructures ha...

[Advanced Materials] Fabrication of Micro-Patterned Stimulus-Responsive Polymer Brush ‘Anemones’
<!--[endif]-->
We present a simple strategy to fabricate stimulus-responsive patterned pNIPAAM brush microstructures (‘anemones’). Our approach relies on the combination of three phenomena: (1) the unusual phase separation of two differently functionalized alkanethiols on the stamp surface or during ink transfer in mCP on the substrate surface, (2) the preferred deposition of the ...
