Sandrine Martin Michael Hamilton Jerzy Kanicki* Abstract — Organic-polymer-based thin-film transistors (OP-TFTs) look very promising for flexible, large-area, and low-cost organic electronics. In this paper, we describe devices based on spin-coated organic polymer that reproducibly exhibit field-effect mobility values around 5×10–3 cm2/V-sec. We also address fabrication, performance, and stabil...

Using the enormous magnetic field gradients present near the surface of magnetic recording media, we assemble diffraction gratings with lines consisting entirely of self-assembled magnetic nanoparticles that are transferred to flexible polymer thin films. These nanomanufactured gratings have line spacings programmed with commercial magnetic recording and are inherently concave with radii of cur...

A polymer gel (ferrogel) is an assembly of ferromagnetic nanoparticles embeded in gel. In the ferrogel, the finely distributed magnetic particles are suspended in the swelling liquid and forma flexible matrix due to adhesive forces. The present paper describes an electric and acoustic study of magnetic field sensitive poly (dimethyl siloxane) ferrogel. The results showed hysteresis of acoustic ...

UV curing nanoimprint lithography is one of the most promising techniques for the fabrication of micro- to nano-sized patterns on various substrates with high throughput and a low production cost. The UV nanoimprint process requires a transparent template with micro- to nano-sized surface protrusions, having a low surface energy and good flexibility. Therefore, the development of low-cost, tran...

Optical sensors for detecting temperature and strain play a crucial role in the analysis of environmental conditions and real-time remote sensing. However, the development of a single optical device that can sense temperature and strain simultaneously remains a challenge. Here, a flexible corner cube retroreflector (CCR) array based on passive dual optical sensing (temperature and strain) is de...

This work reports a novel and general synthesis of aligned carbon nanotube/polymer composite films with high optical transparency, robust flexibility, and excellent conductivity. These composite films show many potential applications such as flexible conductors for optoelectronic devices.

We employed a floating chemical vapor deposition technique and applied a liquid (solution)-free precursor system for the fabrication of single-walled carbon nanotube macro-films on various flexible substrates from metallic foils to polymer films.

A flexible one-dimensional Cu(II) coordination polymer with shape-recognizing space shows selective adsorption of larger 2-butanone guests from Lewis-base mixtures containing 2-butanone-EtOH or 2-butanone-MeOH.

A one-dimensional coordination polymer based on planar pentanuclear copper(II) clusters has been assembled from a flexible tripodal ligand, which exhibits a quite strong antiferromagnetic coupling between Cu(II) ions.

Six bidentate building blocks have been used to form a tripodal ligand with a flexible C3 symmetric spacer to direct the assembly of large octametallic clusters covalently linked to form a 1-D highly luminescent terbium tube-like polymer.
