Cyclodextrins and their applications

Cyclodextrins can complexate with polymers and thus can be grafted to surfaces. Grafted layers of sliding polymers are constructed from polymers threading through ring-like molecules grafted to a surface. Such grafting mode allows the polymer chains to freely slide inside the ring-like molecules, thus providing additional degree of freedom for grafted polymers.
A cyclic molecule of a cyclodextrin consist […]

Following up a recent paper on grafted sliding polymer layers [Macromolecules 2005, 38, 1434−1441], we investigated the influence of the sliding degree of freedom on the self-assembly of sliding polymeric surfactants that can be obtained by complexation of polymers with cyclodextrins. In contrast […]

Sliding grafted polymer layers

We study theoretically the structure of sliding grafted polymer layers, or SGP layers. These interfacial structures are built by attaching each polymer to the substrate with a ringlike molecule such as cyclodextrins. Such a topological grafting mode allows the chains to freely slide along the […]
