Effect of Calendering and Surface Treatment on the Thermochromic Response of Cholesteric Liquid Crystals on PET Nonwovens

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the influences of calendering and surface treatment during direct ink writing (DIW) of thermochromic cholesteric liquid crystal (CLC) on PET nonwovens. For the PVA‐coated nonwovens, calendering reduces pore size leading to reduced ink absorption and enhanced spreading. The NeverWet‐coated nonwovens improve thermochromic responses by

One-Pot Synthesis of Arborescent Polystyrenes

open access: yes, 2016
A new grafting-from procedure was developed for the synthesis of arborescent styrene polymers of successive generations in a single reaction pot. Styrene was first copolymerized anionically in a semibatch process with 1,3-diisopropenylbenzene (DIB), and ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Melt rheology of arborescent graft polystyrenes [PDF]

open access: yes, 1998
Arborescent graft or comb-burst polymers are highly branched, high molecular weight polymers that are constructed from linear polymer chains by a cascade grafting process. The arborescent graft polystyrenes studied here were prepared by a "graft on graft"

Regulated Ion‐Diffusion Hydrogels for Subtle and Multimodal Temperature‐Strain Sensing in Wound Monitoring

open access: yesAdvanced Functional Materials, EarlyView.
A soft, dual‐channel hydrogel patch enables simultaneous detection of wound temperature and strain by integrating ion‐diffusion‐mediated thermoelectric and resistive sensing. The conformal design maintains stable performance during motion, capturing subtle inflammatory and mechanical changes for continuous wound monitoring.

Thermal behavior and degradation mechanism of brominated polystyrenes

open access: yes, 1995
Polystyrene samples have been brominated under various conditions. p-Bromostyrene has been polymerized using ?,??-azobisisobutyronitrile as initiator. The thermal behavior of these brominated polystyrenes was investigated by pyrolysis-gas chromatography ...
