Hydrogenated P(VDF-co-TrFE)s with low TrFE molar contents are synthesized by atom transfer radical chains transfer (ATRCT) and controllable elimination reactions. Then related characterization methods with the aid of DSC techniques are employed to evaluate the crystalline phase transition phenomenon, which shows that the all-trans beta phase could be found(More)
Different thermal treatments were used to obtain various crystal structures of hydrogenated poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] films synthesized by an atom transfer radical chain transfer and controllable elimination reaction route. After analyzing the results of X-ray diffraction and differential scanning calorimeter, we found that(More)
Multispectral image contains much more information than regular RGB image so that it has wide applications in the field of physics, surveillance, environment monitoring or investigation of artworks. The traditional spectral imaging cameras are mainly based on broom/scanning or filter wheel imaging technologies, while those techniques share significant(More)
On the basis of Lambert-Beer law and the theory of light ray propagation, the color-matching-model in gravure related to the substrate and three primary printing ink-cyan, magenta and yellow was established in this paper. The results shown that by using color difference formula CIEDE2000, the difference between calculated color value and target color value(More)
