Abstract:
A reversible rotaxane polymer network comprising a first polymer including a linear segment and a second polymer including at least one macrocycle bonded to said second polymer, said macrocycle being capable of being physically threaded onto said linear segment to form a rotaxane complex by a first external factor selected from the group consisting of solvent exposure, temperature change and combinations thereof to create a polymer network from said first and second polymers wherein said first and second polymers are joined by said rotaxane complex, said macrocycle being capable of being physically unthreaded from said linear segment by a second external factor selected from the group consisting of solvent exposure, temperature change, and combinations thereof, wherein said linear segment of said first polymer includes one or more of a 4,4'-bipyridinium moiety.
