Abstract
Leveraging metal-coordination crosslinks for materials design of polymers can enable fine-tuning of the mechanical properties of rubbers without requiring the use of sophisticated vulcanization pathways. In this work, we synthesized several polyisoprene-graft-histamine gels in toluene, coordinated by Ni²⁺ and Co²⁺ ions. In addition, we synthesized polystyrene-graft-histamine-Ni(OH)₂ composites in DMF, with Ni(OH)₂ nanoparticles nucleated and grown in situ upon the addition of a hydroxide. The viscoelastic mechanical properties of these materials are improved relative to the base polymers.
