Nanostructuring polymers with cyclodextrins

and yCDs schematic representation of packing structures of (c) cage-type, (d) layer-type and (e) head-to-tail channel-type CD crystals and (f) CD-IC channels containing included polymer guests. 

The formation of and coalescence from polymer-CD-ICs are briefly described along with the methods used to characterize both the ICs and the coalesced guest polymers. Here the focus is on the structural organization of solid polymer samples coalesced from their CD-ICs, which are found to be quite distinct from solid polymer samples formed from their randomly coiling and entangled solutions and melts. The alteration and control of properties displayed by solid polymers coalesced from their CD-ICs are also discussed. 

Polymers treated with and containing CDs, but that are only partially or not included at all by CDs, or that are covalently bound to CDs, are also considered, with particular emphasis placed on how their properties may be modified and controlled by their constituent CDs. 

Formation and characterization of polymer-cyclodextrin-inclusion compounds 

Formation of polymer-CD-ICs (see Fig. 11.If and 11.2) begins with either the dissolution or suspension of CD cage-structure crystals (see Fig. 11.1c) or their conversion to chaimel- or columnar-stmcture crystals (see Fig. 11.le) containing only water of hydration as a guest. The formation of crystalline polymer-CD-ICs from solutions requires the combination of solutions
