摘要：

The extent of hydrogen-deuterium exchange depends on the accessibilities of the ordered and less ordered regions of the cellulose fibers. Because of the difference between the coherent scattering lengths of H and D the deuterium exchange raises the scattering contrast in a neutron small-angle scattering experiment. Selectively deuterated samples exhibit meridional long spacing reflections in the range of 150 to 200 A: These reflections are not given by untreated samples. The intensity analysis of the first layer line yields a lateral fibril dimension of 34 A in the case of Fortisan. The central diffuse scattering of natural cellulose can be explained by lozenge-shaped voids which could be related to 120° kinks in the microfibrils. © 1978, American Chemical Society.
