To fabricate transparent conducting films (TCFs) for electronic devices, both a high conductivity and thermal stability are significant issues due to the need for a high temperature annealing process. In this report, we describe the preparation of a highly transparent (94% transmittance), conductive (surface resistivity: 354 Ω sq−1) and thermally stable double-walled carbon nanotube (DWCNT) film without adding any chemical doping or rinsing. Such film was obtained by a simple dilution and condensation/filtration process (DC/F). The procedure is quite simple, and thus large scalability is easy.

Gold (Au) nanoparticles having a Pt-shell layer (Au-Pt) deposited on a conductive support are a promising electrocatalyst for fuel cells for in order to minimize the use of Pt. We describe a facile one-pot method to grow Au-Pt having a 3.8-nm diameter on multi-walled carbon nanotubes (MWNTs) without using any reducing agent, in which polybenzimidazole was used as the binding sites on the MWNTs to load the Au-Pt.

The successful Layer-by-Layer assembly formation using a polyanion and trivalent ion, such as Fe3+, on the surfaces of the nanopores in an anodic aluminum oxide (AAO) membrane with a pore diameter of 35 nm is demonstrated.

Poly(N-isopropylacrylamide) (PNIPAM) was coated on gold nanorods (NRs) without forming aggregates. The PNIPAM-coated NRs (PNIPAM-NRs) formed aggregates at higher temperature than the lower critical solution temperature (LCST) of the PNIPAM layers. The aggregation showed reversible spectroscopic responses under repeated temperature cycles. When near infrared (near-IR) light irradiated a PNIPAM-NR solution, the temperature raise up, and formed aggregates that showed broad and weak surface plasmon bands. The spectroscopic responses in near-IR region work as a negative feedback for heating a photoirradiated nanorod solution. The feedback offers spontaneous temperature control of the photoirradiated solution at LCST of PNIPAM.
