Novel Hybrid Titania Nanocomposites as Efficient and Recyclable
Photocatalyst
L Gao, XF Song, Q Zhang (Shanghai Institute of Ceramics)
Four types of novel hybrid titania nanocomposites including titania nanoparticles immobilized
on ZnO tetrapods, hollow silica/titania microspheres, polystyrene/silica/titania spheres and
titania/silica-coated magnetic spheres have been prepared with well controlled microstructure.
They showed higher photocatalytic activity in the degradation of phenol or methylene blue
under UV or visible light irradiation with easy to be separated and recyclable use feature.

CTBN/Epoxy/Carbon-Black Nano-Composites With Impact-Energy
Absorbablity
H Kishi, K Imai, A Nagao, S Matsuda (Univ of Hyogo)
Nano-composites consist of carboxyl-terminated butadiene acrylonitrile rubber (CTBN) /
epoxy and carbon-black (CB) particles were formulated. The impact-energy absorbability of
the nano-composites depended on the temperature for kneading the components. Strong
interaction formed at the interface between CTBN and CB would be the key factor for the high
impact-energy absorbability. (E3:3)

Mulitiferroic nanocomposite Fe2O3/BiFeO3 were synthesized by solid state reaction from the
precalcined mixture of Bi2O3 and Fe2O3 as starting materials. The nanocomposite ceramics
were characterized by XRD, FESEM, XPS techniques. It was confirmed that Fe2O3 and
BiFeO3 are distributed uniformly in the ceramics. The ferroelectric and ferromagnetic
properties were evaluated. (E3:4)

Nanotube Grafting on Porous Surfaces for Enhanced Surface
Functionality
S Mukhopadhyay, I Barney (Wright State Univ)
Carbon nanotubes (CNT) have been grafted on microcellular graphite to increase its surface
area without increasing bulk. The key to dense CNT growth inside pores is a pre-coating of
reactive oxide. These hierarchical structures show significant improvement of surface related
properties such as thermal dissipation, cell growth and composite formation. (E3:6)

Nanofibres
F Ko, M Bayat, H Yang (Univ of British Columbia)
Polyacrylonitrile(PAN)-Fe3O4 composite nanofibres were fabricated by the co-electrospinning
process. These nanofibres were carbonized to obtain tailored electromagnetic properties.
Four-probe and SQUID measurements showed tailorable electromagnetic properties were
achieved by controlling nanoparticles contents and carbonization temperature. (E3:7)

Carbon Nanocomposites at Microwave Frequency Band
JB Kim, SK Lee (KIST) CG Kim (KAIST)
In this paper, we have studied on the numerical model for the complex permittivity of carbon
nanocomposites in microwave frequency band based on the percolation theory. The model
was build up for complex permittivity of E-glass fabric/epoxy composite laminates containing
carbon nano fibres (CNF) at the frequency band of 0.5 GHz ~ 18.0 GHz. (E3:9)

S Gao, RC Zhuang, J Zhang, JW Liu, E Mäder (Leibniz-Institut)
A single glass fibre sensor has been manufactured by depositing multiwalled carbon
nanotube (MWNT) networks on fibre surface aimed at multi-functional applications. Nonlinear
and linear piezoresistivity and temperature dependences have been identified in the single
glass fibre sensors and their epoxy matrix composites. Our unidirectional composites exhibit
anisotropic electrical and semiconducting properties. (E3:10)

A de la Vega, K Schulte, W Bauhofer (TU Hamburg-Harburg)
Single-walled carbon nanotubes at concentrations just above the percolation threshold were
added to thermoset matrices as internal stress sensors. The Raman strain-induced shifts of
the nanocomposites were investigated throughout the curing cycle and under mechanical
load. Residual stresses originated from the post-cure cooling are found to affect significantly
the mechanical strength of the material. (E3:11)

Preparation, Structure, Performance, Industrialization and Application of
Advanced Rubber/Clay Nanocomposites
L Zhang, Y Wu, Y Wang, Y Lu (Beijing Univ)
Clay/polymer nanocomposites have attracted great interests in the field of materials science
and engineering for some superior properties. However, further development is limited by
reasons like high price/performance ratio and deficiency in some properties. To break
through the bottleneck we have to (1) develop preparation techniques with low cost; (2)
exploit the acquired excellent properties and find optimum application fields. (E3:13)

To increase the electromagnetic wave absorbing properties in radar frequency region,
high aspect ratio Fe nanofibers have been fabricated by the multi-nozzle
electrospinning process. In the present study, the effect of different applied voltage on
the morphology of electrospun Fe nanofibers was examined. The average diameter of
electrospun Fe nanofibers tended to decrease with increasing applied voltage.

Investigations of melt compounded PLLA/nHA nanocomposites have provided evidence
for a significant reduction in the rate of crystallization at temperatures greater than 110 °C
in the presence of the nHA, believed to be associated with a modification in the matrix
crystal structure. Possible consequences for the practical implementation of these
nanocomposites in bone tissue engineering will be discussed. (E3:16)
