Cross-linked polymer networks based on polysiloxane and nickel β-diketonate precursors
Abstract
Abstract Elastic cross-linked by metal-ligand interaction networks based on polysiloxanes have attracted wide attention in the field of materials science as materials with self-healing, shape-memory and recyclable elastomeric properties. A series of novel cross-linked polymers based on linear polysiloxane and metal β-diketonate precursors by the reaction of multiligand PDMS with grafted β-diketonate fragments and Nickel (II) acetate have been successfully prepared and fully characterized. Physicochemical, mechanical, rheological and thermal properties of all polymers are studied. The proposed approach to preparation coordination polysiloxane polymers can be usefully utilized at the design and development of new smart materials with unique properties and easy recyclability.
