Research on internal three-dimensional (3D) strain evolution of a failure process was conducted on a short carbon fiber-reinforced composite through high-resolution (0.33 μm/pixel) in situ synchrotron radiation X-ray computed tomography. Material microstructure and strain value were analyzed simultaneously in 3D for the first time. The distribution of strain fields is nonuniform under load sequences...
Graphene/MxWO3 (M=Na, K) nanocomposites with different weight ratios were successfully synthesized using MBH4 as a reducing agent in aqueous solution, followed by crystallization of amorphous precursors under calcination in H2 (5vol.%)/N2 atmosphere at 600°C. The coupled samples showed good shielding properties in NIR wavelength range together with certain visible lights transparency. The as-prepared...
As a two-dimensional crystal, the graphene sheet is often used with substrate materials because the freestanding graphene tends to corrugate and can hardly display its extraordinary properties in devices. However, the substrate is rarely perfectly-flat, but has microscopic roughness. Whether or not the graphene sheet can conform fully to a substrate with nano- and micro-roughness is essential for...
Flexible transparent conductive films (TCFs) are vital to promote the development of flexible and foldable devices including touch panels, displays, organic solar cells, etc. We have prepared a large-area, flexible, and color-neutral single-wall carbon nanotube:sodium dodecylbenzene sulfonate/poly-(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (SWCNT:SDBS/PEDOT:PSS) composite TCF on a poly(ethylene...
In spite of worldwide research, carbon nanotubes (CNTs) still have not fully realized their original promise as ideal reinforcements for composite materials due to a number of challenging issues such as weak interface, poor dispersion, misalignment and lack of optimized design. Here we propose a bio-inspired structure of CNT bundles with controllable crosslink density and staggered pattern of organization...
The 11th National Symposium on New Carbon Materials was held in Taiyuan, Shanxi, PR China, hosted by the Institute of Coal Chemistry, Chinese Academy of Sciences, during August 16–20, 2013. About 300 attendees participated in the conference, and 142 papers were accepted for discussion, including plenary lectures, keynotes talks, oral presentations and poster presentations. The papers were classified...
This paper presents a convenient one-pot hydrothermal strategy for the synthesis of graphene nanosheet (GNS)/hydroxyapatite (HA) nanorod composites (GNS/HA). Characterization of GNS/HA nanorod composites denote that rod-like HA, which has an average length of 55nm and diameter of 13nm, anchors on both sides of GNS. Introducing graphene can effectively improve the hardness and Young’s modulus of HA...
This paper gives a brief review of the adsorption of organic pollutants on mesoporous carbons and carbon/silica hybrids prepared using soft and hard templating methods. These adsorbents include both pristine and modified ones such as metal-loaded, ammonia-treated, KMnO 4 -oxidized, CO 2 -activated, and octyl-grafted carbons and hybrids. The adsorbates cover small-molecule pollutants...
Water-soluble hydroxylated multi-wall carbon nanotubes (MWCNTols) were synthesized by the NaOH/H 2 O 2 oxidation method. A L 9 (3 4 ) orthogonal experimental design was used to optimize the preparation conditions, and TEM, SEM and Raman spectroscopy were used to characterize the products. The solubility of as-prepared MWCNTols in water was 0.72mg/mL. Furthermore, MWCNTols...
Carbon nanotube/cubic nickel cyanoferrate/polyaniline hybrid films were synthesized by cyclic voltammetric electrodeposition of NiSO 4 , K 3 Fe (CN) 6 and aniline in a H 2 SO 4 /Na 2 SO 4 solution on a platinum electrode coated with carbon nanotubes. The electrocatalytic oxidation performance for ascorbic acid (AA) using the hybrid film as an...
Patterning is an essential and important process for the future use of single-walled carbon nanotube (SWCNT) thin films (TFs) in electronic devices. Different from traditional Si based electronic materials, SWCNTs can be easily etched when exposed to an oxidative atmosphere. Here we propose a gas exposure method to pattern SWCNT TFs on flexible polymeric substrates, without using vacuum and high temperature...
