Journal ArticleDOI
Deformation-Induced Color Changes in Melt-Processed Photoluminescent Polymer Blends
TL;DR: The phase behavior of these blends, which comprised 0.01−3% w/w of the PL guest, could be controlled via the molecular structure of the dye, its concentration, and the processing conditions as discussed by the authors.
Journal ArticleDOI
Rotaxanes as Mechanochromic Fluorescent Force Transducers in Polymers
Yoshimitsu Sagara,Marc Karman,Ester Verde-Sesto,Ester Verde-Sesto,Kazuya Matsuo,Yuna Kim,Nobuyuki Tamaoki,Christoph Weder +7 more
TL;DR: This work has shown that the molecular-shuttle function of rotaxanes can be extended to mechanical activation, and a mechanically interlocked mechanophore composed of a fluorophore-carrying macrocycle and a dumbbell-shaped molecule containing a matching quencher was integrated into a polyurethane elastomer.
Journal ArticleDOI
Fluorescent Sensors for the Detection of Chemical Warfare Agents
TL;DR: Recent activities regarding the development of molecular sensors that can visualize the presence of nerve agents (and related pesticides) through changes of their fluorescence properties are outlined.
Journal ArticleDOI
Polymer nanocomposites with nanowhiskers isolated from microcrystalline cellulose.
Jeffrey R. Capadona,Kadhiravan Shanmuganathan,Stephanie Trittschuh,Scott Seidel,Stuart J. Rowan,Christoph Weder +5 more
TL;DR: Nanocomposites based on an ethylene oxide/epichlorohydrin copolymer and nanowhiskers isolated from MCC were produced that display the maximum mechanical reinforcement predicted by the percolation model.
Journal ArticleDOI
pH-Responsive Cellulose Nanocrystal Gels and Nanocomposites
TL;DR: In this paper, the authors show that functionalization of the surface of cellulose nanocrystals with either carboxylic acid (CNC-CO2H) or amine(CNC−NH2) moieties renders the CNCs pH-responsive.
