Redox- and mechano-chromic response of metallopolymer-based elastomeric colloidal crystal films

Abstract

A novel and convenient route for the preparation of monodisperse ferrocene-containing core-interlayershell particles using emulsion polymerisation protocols is described. These metallopolymer-based particles can be used to produce highly ordered elastomeric opal films with fascinating distinct reflection colours.The present work additionally describes the combined addressability of both stimuli, redox-chemistry and mechanical stress. The obtained materials are interesting since application of the melt-shear process followed by crosslinking of the matrix provides access to large-area, mechano-responsive elastomeric opal films featuring an additional redox response. Both, basic synthesis aspects and first steps towards application in the field of stimuli-responsive sensing of respective materials are discussed.

Structural color coating films composed of an amorphous array of colloidal particles via electrophoretic deposition

“…The hue of such structural color shows variations that depend upon the viewing and light-illumination angles. 43 Therefore, the large peak shift Figure 5 Reflection spectra of the coating films corresponding to a change in measurement angle. The incident angle relative to the normal of the planar surface of the membrane was 0°.…”

Smart polymer inverse-opal photonic crystal films by melt-shear organization for hybrid core–shell architectures

“…33,34,[49][50][51][52] Inspired by this work, we now conceived the technique for the novel thermoresponsive silica@PEA@P(DEGMEMA-co-EA) and sili-ca@PMMA@P(NIPAM-co-MMA) hybrid CIS particles to prepare hybrid OPC and polymer IOPC lms by applying melt-shear organization, cross-linking (xlink) and subsequent etching of the silica cores, thus avoiding the inltration stage and the cracking of the lms. 33,34,[49][50][51][52] Inspired by this work, we now conceived the technique for the novel thermoresponsive silica@PEA@P(DEGMEMA-co-EA) and sili-ca@PMMA@P(NIPAM-co-MMA) hybrid CIS particles to prepare hybrid OPC and polymer IOPC lms by applying melt-shear organization, cross-linking (xlink) and subsequent etching of the silica cores, thus avoiding the inltration stage and the cracking of the lms.…”

Redox-responsive polymeric membranes via supermolecular host–guest interactions

“…Numerous studies on redox-responsive materials have been executed nowadays. These materials have great potential in applications of controlled release or drug delivery [1][2][3][4], self-healing [5,6], switching surface properties [7,8], electrically induced optical properties [9,10] and sol-gel transition [11][12][13], due to their responses to external and/or internal redox-stimuli signals.…”
