Nematic monodomain liquid crystalline elastomers have been prepared through in situ cross-linking of an acrylate based side-chain liquid crystalline polymer in a magnetic field. At the nematic–isotropic transition, the sample is found to undergo an anisotropic shape change. There is found to be an increase in dimensions perpendicular — and a decrease parallel — to the director, this is consistent...
Voltage contrast scanning electron microscopy has been exploited to investigate the operating stability of conductive polymer composite resettable fuse devices. It has been shown that the technique enables the active region of the device to be imaged and, hence, its position and shape to be compared after a succession of operating cycles and as a consequence of the position of the attached surface...
