Nanoclay-reinforced Nanocellulose Composite Films with Improved Heat resistance, Gas Barrier Performance, and Mechanical properties

Ryu J.H., Jeong Y.G., Chungnam National University, KR

Since nanocellulose (NC) has excellent strength, modulus, lightness, and thermal stability, it has been widely utilized for composites, electronics, sensors, papers, coatings, films, aerogels, health care, additives, etc. In this study, to attain NC films [...]

Graphene oxide/vinyl ester resin nanocomposite: the effect of graphene oxide, curing kinetics, mechanical properties and thermal stability

Arabli V., Aghili A., Islamic Azad University, Shiraz, IR

Graphene oxide (GO) was synthesized and nanocomposite was achieved using different contents of the GO and Vinyl Ester Resin (VE). The suspension was sonicated in order to prevent the agglomeration. Non-isothermal differential scanning calorimetry (DSC) [...]

A Bulk, Low Energy Surface Treatment for Three Dimensional Substrates via CVD Processing

Smith D., Patterson L., SilcoTek Corporation, US

There are myriad potential applications and a significant need for low energy surfaces. The gas-phase modification of three dimensional structures, such as fittings, tubing, valves, or manifold blocks, in high volume, to give hydrophobic and [...]

Epoxy/Silica Nanocomposite: Effect of Silica Nanoparticles, Thermal Stability, and Modeling of the Curing Kinetics

Rahim Vaseghi M., Arabli V., Aghili A., Islamic Azad University, IR

A nanocomposite was synthesized using silica nanoparticles (SN) and Epoxy Vinyl Ester Resin (VE671). Nanoparticles were dispersed in the mixture by ultrasonic equipment to prevent the agglomeration. Transmission electron microscopy (TEM) was used to investigate [...]

Retarded Growth of Nano-sized Carbide Particles in Liquid Metals at 1500°C

Kim J., Kim J., Seo M., Kim J., Kang S., Seoul National Univ., KR

The nanocrystalline solid-solution carbide powders were prepared by carbo-thermal reduction after high-energy planetary milling of proper oxide mixture. Then, particle growth behaviours of nanocrystalline transitional metal carbides such as (W,V)C and (Ti,W,M1,M2)(CN) were investigated and [...]

Magnetic Carbon-Nanotube Thermoplastic Polyurethane Composites

Kong I., Spoljaric S., Shanks R.A., RMIT University, AU

The aim was to prepare composites of PU and magnetite-functionalized CNTs, using physical blending techniques in melt and solution. Objectives included functionalizing the CNT with magnetite (Fe3O4), preparing PU-CNT-Fe3O4 composites using solvent dispersion and melt [...]

Thermal Stability of Carbon Nanotubes produced by CCVD of Ethylene by using Different Supports

Giraldo L.F., López B.L., Barrera G.M., Universidad de Antioquia, CO

In the synthesis of carbon nanotubes two of the most important parameters to consider are the type of support and the kind of catalytic metal. In this work we have studied the thermal stability of [...]
