A study of the interaction between nanoparticles and light: an experimental proof and visualisation of Mie theory in polymer composites

Wrigglesworth E.G., Johnston J.H., Victoria University of Wellington, NZ

An experimental proof of Mie theory has been developed using gold nanoparticles. The relationship between nanoparticle size and the ratio of scattering to absorption has been investigated, and nanoparticle – polymer composites have further been [...]

Kinetics study of carbon nanotube alignment under shear force via real-time polarized Raman spectroscopy

He Y., Taub A.I., University of Michigan-Ann Arbor, US

Carbon nanotubes (CNTs) have been studied extensively since their discovery by Iijima in 1991. They have a unique quasi one-dimensional nanoscale structure with remarkable mechanical, electrical and thermal properties. Numerous investigations have been done on [...]

Release of Carbon Nanotubes from Nano-polymer Composites during Environmental Aging

Sahle-Demessie E., Han C., Zhao A., Wang J., Grecsek H., U.S. Environmental Protection Agency, US

Over the past two decades there has been a significant increase in commercial products incorporating engineered nanomaterials (ENM) that are now are used in electronic, cosmetics, automotive and medical products and in environmental applications. Although [...]

Thermal conductivity model for polymer/Boron Nitride nanocomposite considering air void content

Park S.Y., Kim J.H., Shin M.W., Yonsei University, KR

Polymer/Boron Nitride (BN) nanocomposite is promising interfacial material for cooling of electronic systems. It is important to determine percolation threshold when it practically uses in the industry. But, the exact prediction with existing model is [...]

Characterization of poly(vinyl alcohol)-based composites prepared by electrospinning technique with in situ coffining process

Hara C., Tsutsumi H., Yamaguchi University, JP

A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. We propose new type reinforced polymer composites by electrospinning technique with in situ coffining [...]
