“…35) Recently, it has been reported that the aggregate morphology of sexithiophene materials can be tuned using different solvents from the results of X-ray scattering and magnetic orientation. 40) The solvent (o-DCB) for the formation of the P3BT nanowires in this study is different from that (p-xylene) for the formation of the P3HT nanowires in our previous study. 35) Therefore, the difference in magnetic orientation between the P3BT and P3HT nanowires is probably attributable to the difference in nanostructure between the nanowires, where the directions of -stacking are parallel to the long axes of the nanowires in the present P3BT nanowires (Fig.…”

Nanowires consisting of regioregular poly(3-butylthiophene) (P3BT) were prepared using o-dichlorobenzene. The magnetic processing of the nanowires was carried out using a superconducting magnet in the vertical (B max ¼ 10 T) direction. The formation of the nanowires was confirmed by atomic force microscopy (AFM). The polarized absorption spectra of the nanowires on a glass plate in the absence and presence of a magnetic field indicated that the nanowires partly oriented in the presence of magnetic fields (6 and 10 T). The magnetic orientation is most likely attributable to anisotropy in the magnetic susceptibility of the ordered P3BT in the nanowires. The AFM images of the nanowires on mica and the polarized absorption spectra of the nanowires on glass plates indicate that the nanowires partly oriented themselves with their long axes, which are perpendicular to the -stacking direction, parallel to the magnetic field. #

“…The entrance cone of the SAXS vacuum pipe as well as the WAXS detector are mounted on a moving support that can be displaced in order to fit equipment with large lateral size (up to 1-2 m). Several complex sample environments have successfully been implemented, such as superconducting magnets (McCulloch et al, 2011;Siemianowski et al, 2012;Gielen et al, 2009) or even fuel and waste gas handling systems for controlled soot formation experiments (Gardner et al, 2005).…”

Recent developments on the experimental infrastructure and the acquisition of new detectors on the Dutch-Belgian beamline BM26B at the ESRF offer novel and promising possibilities for synchrotron X-ray experiments in the field of polymer crystallization under processing-relevant conditions. In this contribution, some of the most recent experiments mimicking conditions similar to those relevant for the plastics processing industry are discussed. Simultaneous thermal analysis and wide-angle X-ray scattering (WAXS) experiments, at the millisecond time-frame level, on -nucleated isotactic polypropylene (i-PP) samples subjected to ballistic cooling up to 230 K s À1 , show that the efficiency of the nucleating agent can be suppressed when quenched cooling rates higher than 130 K s À1 are used. In situ WAXS experiments using small-scale industrial equipment during a real film blowing process reveal the dependence of the onset of crystallinity (the so-called freeze line) and the crystal orientation as a function of different take-up and blow-up ratios. In situ small-angle X-ray scattering (SAXS) experiments during high-flow fields reveal the formation of shish and kebab structures in i-PP as a function of the imposed stress. Quantitative analysis of i-PP flow-induced structures is presented. The beamline specifications required to obtain high quality and industrially relevant results are also briefly reported.
