Deuterated polymer
WebNeutron scattering has found wide use for the characterization of polymers owing to the partial deuteration method. Use of deuterated macromolecules in a non-deuterated environment is comparable to the staining method used in electron microscopy in order to enhance contrast. WebDeuterated polymers Sorting.

WebNov 8, 2024 · When isotopically labeling polymer chains for small-angle neutron scattering (SANS), it is highly desirable to achieve even intra- and interchain distributions of deuterium (D), such that scattering centers are uniformly placed along and among the chains. A common approach to introduce D is to catalytically saturate an unsaturated precursor … WebFeb 28, 2024 · Deuterated polymer is a special functional polymer material in which the hydrogen atoms in its molecular chain are replaced with deuterium. According to the source, deuterated polymers can be divided into deuterated natural polymers and deuterated synthetic polymers. Deuterated natural polymers include deuterated starch, …
WebA technique called contrast variation reveals extra information about polymers if some of the hydrogens normally present are replaced by deuterium. For example, regions of the polymer chain can be selectively labelled and investigated like the chain ends or the middle part. Unfortunately, the synthesis of deuterated polymers is not easy. WebMay 18, 2007 · Abstract. In the rich and long-standing literature on the flow-induced formation of oriented precursors to polymer crystallization, it is often asserted that the longest, most extended chains are the dominant molecular species in the “shish” of the “shish-kebab” formation. We performed a critical examination of this widely held view ...
