Separation and analysis technology

CD polymers (CDPs) are macromolecule derivatives which carry multiple CD units. These units are appended by chemical bonding or physical mixed method. These kinds of polymers not only have the better ability of identification and encapsulation, but also possess good mechanical strength, stability and chemical tenability. The comprehensive function of CD cavity and polymer network could improve the properties of materials. The early investigations always focused on the formation of CDPs by monomers copolymerization. However, several papers showed that the CDs could link to the natural macromolecules to form novel polymers. These polymers were expected to be applied in the functional materials, separation and analysis technology, biomedical engineering, environmental and other high-tech fields [17]. 

According to differences in water-solubility, CDPs can be divided into water-soluble, water insoluble and water swelling CDPs. Water insoluble CDPs have applications in separation and analysis technology, trace organic capture and special material because CDPs can be easily separated and are recyclable. Most CDPs belong to water insoluble polymer. Some other water-soluble CDPs, especially bonding to native polymer chain, may become the new materials and carriers for drug development formulations.
