Metals in polymers: hybridization enables new functions

Abstract

Adding metals in synthetic polymers is of broad interest to design multifunctional materials, particularly harnessing unique properties and functionalities not found in pure organic polymers. Other than simple emergence of...

Bioelastomers: current state of development

“…Multiple sub-components can be added depending on the desired functionality. 132–137 The interactions between the elastomeric matrix and the sub-components can be physical ( e.g. , van der Waals and electrostatic) or via covalent bonding (mineralization or crosslinking).…”

Three-Dimensional Shape Transformation of Eu3+-Containing Polymer Films through Modulating Dynamic Eu3+-Iminodiacetate Coordination

“…Dynamic metal–ligand coordination has been broadly used to fabricate stimuli-responsive materials. − Among many dynamic metal–ligand coordinations, the disruption and reformation of luminescent lanthanides with ligands can usually switch the mechanical states of the polymers in couple with their luminescence emission of lanthanides, like Eu 3+ . − We recently developed multistimuli-responsive polymer hydrogels and elastomers using the dynamic coordination of Eu 3+ ions with multidentate ligands, like iminodiacetate (IDA) and dipicolylamine (DPA). − The dynamic coordination in polymer hydrogels and elastomers allowed reversible formation/disruption of polymer networks along with tunable fluorochromic properties in response to various stimuli, including metal ions, pH, humidity, temperature, sonication, and force. Given such multistimuli responsiveness of dynamic coordination of lanthanides, we extend our design to create inhomogeneity, thus triggering the 2D-to-3D shape transformation in the interpenetrated polymer networks (Figure a).…”

Hybrid Polymeric Nanostructures Stabilized by Ferric Cations with Photo-Fenton Performance: Implications for Recoverable Multicatalyst Design

“…The recovery of such a catalyst is indeed possible by simple ultrafiltration or dialysis, thus meeting one of the most relevant criteria of green catalysis. Hence, catalyst systems based on inorganic nanoparticles , or metal catalysts complexed with either surfactants or polymers were extensively described in the literature. , Nevertheless, high-performance nanocatalysts often require complex synthesis processes and specific surfactants or stabilizers. − …”
