We present a totally green approach towards the synthesis and stabilization of aqueous graphene dispersions through UV-irradiated reduction exfoliated oxide (GO). Polyvinyl pyrrolidone (PVP) is used to enhance dispersibility reduced (RGO) by one-step functionalization. The proposed method low cost easy without using any photocatalysts or reducing agents, which can open up new possibility for preparation stable RGO in large-scale production.
In the present work, a facile and environmentally friendly method was presented to synthesize nano-boehmite (AlOOH) that added in bisphenol A epoxy resin improve flame retardancy of resin. The crystalline phase as-synthesized AlOOH examined using X-ray diffraction measurements, while no peaks from other are observed patterns, sharp demonstrate high crystallinity AlOOH. Scanning electron microscopy used observe morphology AlOOH; results indicate thickness nanosheets is about 23 nm....
ABSTRACT In this article, sheet boehmite (AlOOH), which was synthesized via a facile and environmental friendly method, used as reinforcing agent to toughen Bisphenol A epoxy resin. The result of X–ray Diffraction (XRD) IR spectrum indicated that the as–synthesized product pure crystalline high purity AlOOH. effects AlOOH on mechanical properties AlOOH/epoxy nanocomposites were investigated. results introduction significantly improved Compared with neat resin, tensile strength fracture...

In order to expand applied field of epoxy resin, its mechanical properties have be improved. Carbon nanotube (CNT) is regarded as an exceptional toughening agent for polymers. However, poor dispersion quality CNT in polymer matrix and weak interfacial force between them commonly lead low reinforcing efficiency. This article presented a study on the composite reinforced with aminated (CNT-NH 2 ). The amination was achieved via wet chemical procedure using 1,6-diaminohexane (DAH) amine source....
The welding tool is the key of micro friction stir (μFSW), which affects heat input and plastic forming weld metal. In this paper, 0.8-mm-thick ultra-thin 1060-H24 aluminum sheets μFSW butt joints were used to compare analyze influence conventional shoulderless on shaping, microstructure mechanical properties. Besides, by measuring axial force, transverse force temperature in process, these two different tools metal flow mechanism analyzed. results show that generated has narrower width,...
In the friction stir welding (FSW) of ultra-thin dissimilar metal sheets, different physical material properties, reduction plastic in weld zone, and insufficient flow lead to poor seam shapes joint qualities. Therefore, it is necessary study behavior during FSW ultrathin sheets. this study, micro (μFSW) was conducted analyzed for butt 0.6-mm-thick brass (H62-H) pure copper (T2-Y) By analyzing electric signals temperature force process, testing mechanical metallography joint, influences...
Boehmite (AlOOH) sheets were synthesized via a hydrothermal method and then successfully functionalized with bi-functional coupling agent, γ-aminopropyl- triethoxysilane (APTES), through facile neutral solvent method. Scanning electron microscope transmission microscopy images showed uniform morphology of AlOOH sheets. APTES was found to be covalently bound The linked can combined an epoxy oligomer ring opening addition reaction. modified used as reinforcing agent reinforce the resin cured...
In this experiment, a quaternary fluorine-free refining slag system of CaO-SiO2-Al2O3-MgO was selected, with basicity ratios 2, 4, and 6 calcium-aluminum 1.5, 2.1, 3. High-temperature “slag-steel equilibrium” experiments were conducted to investigate the influence different calcium–aluminum on morphologies, compositions, sizes, quantities inclusions in H13 steel, aiming improve cleanliness steel meet practical industrial requirements. The experimental results showed that increase ratio...
