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 [...]

Facile Spray Coating in Preparing Anisotropic Composites

Song K., Polak R., Abdalla Askar K., Rubner M.F., Cohen R.E., MIT, US

Anisotropy has been taken advantage in composites to achieve specific mechanical, electrical, magnetic and other functional properties. In composite mechanics, orientation of fiber in polymer matrix will reinforce the composites to the greatest potential along [...]

Role of interlayer interaction in the mechanical properties of a multi- walled carbon nanotube and a single-walled carbon nanotube bundle

Talukdar K., Mitra A.K., National Institute of Technology, Durgapur, IN

Molecular dynamics simulation is performed on a SWCNT bundle made up of four (5, 5) SWCNTs and on an armchair MWCNT taking Brenner’s 2nd generation reactive empirical bond order potential. The interlayer interaction in the [...]

Rheology, Microstructure, and Property of Polylactide/Clay Nanocomposites Prepared with SC-CO2 by Melt Compounding

Jiang G., Chen Z.K., Huang H.X., South China University of Technology, CN

The rheology, microstructure and mechanical properties of polylactide (PLA)/clay nanocomposites were investigated. The nanocomposites were prepared using a twin screw extruder with and without the aid of supercritical carbon dioxide. Results show that there exists [...]

Mechanical and Electrical Properties of CNT/Inorganic Nanocomposites by Molecular Level Mixing Process

Hong S.H., Korea Advanced Institute of Science and Technology, KR

One of the emerging applications of CNTs is the reinforcement of composite materials to overcome the performance limits of conventional materials. However, because of the difficulties in distributing CNTs homogeneously in metal or ceramic matrix [...]

Mechanical Properties of Nano-Structure Controlled Ti-Hf Alloy for Dental Implant

Jeong Y.H., Choe H.C., Ko Y.M., Park S-J, Kim D.K., Brantley W., Chosun University, KR

Objectives: Cp-Ti has a excellent biocompatibility. So, it was widely used dental implants and artificial joint. But it is not strong enough for some dental applications. Since Hf belongs to the same group as Ti [...]

Ab Initio Simulation on Mechanical and Electronic Properties of Nanostructures under Deformation

Umeno Y., Kitamura T., Kyoto University, JP

Nanostructures have been attracting attention because of their prominent properties, and their applications for novel devices with advanced functions have been attemted. Large stress and strain occur in local regions in materials with nanostructures owing [...]

Mechanical Properties of SiC Nanotubes

Moon W.H., Ham J.K., Hwang H-J., Chung-Ang University, KR

We investigate the mechanical properties of SiC nanotubes using molecular dynamics simulation. We find that SiC nanotubes are less stiff than the other nanotubes considered so far, such as BN or C nanotubes. However, Youngs [...]

Monte Carlo Simulation Study of Mechanical Properties of Au Nanowires

Tanimori S., Shimamura S., Yamaguchi University, JP

We have carried out Monte Carlo simulations of elongation and shear of Au nanowires to investigate their mechanical properties. We have followed stable atomic arrangements in the nanowires during deformation. The Morse potential has been [...]
