Shape recovery and reprocessing of polyurethane networks crosslinked via host-guest inclusion complexation of adamantane with β-cyclodextrin
In this contribution, we reported a novel strategy to crosslink polyurethane (PU) via host-guest inclusion complexations. First, a linear PU with adamantane (Ad) as side groups was synthesized with a 1,3-diol bearing adamantane as the chain extender. Thereafter, this linear PU was crosslinked with a poly(β-cyclodextrin) through host-guest inclusion complexations to afford PU-Ad-CD networks. In comparison with the linear PU, the PU-Ad-CD networks exhibited improved mechanical properties with the Young's modulus of 43.21 MPa, which was more than eight times as that of the linear PU. The formation of inclusion complexes enabled the PU-Ad-CD networks to display reprocessing properties. In addition, the shape memory properties of the networks featured the reconfigurability of original shape with the aid of the exchange of the host-guest inclusion complexations. This study provides new insights into the development of high-performance PU materials.
期刊介绍：
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
