Construction of a corresponding empirical model to bridge thermal properties and synthesis of thermoresponsive poloxamines

Designed Monomers and Polymers
The thermoresponsive properties of poloxamine (tetra-branch PEO-PPO block copolymer) hydrogels are related to several variables. Of particular interest to this study were the molecular weight of the polymer, the molar ratio between PEO and PPO blocks ...

Autonomous and Continuous Atmospheric Water Harvesting Using Modified Wood

Advanced Science, EarlyView.
A rigid, hydroxyl‐rich wood skeleton with graded channels is used as a multifunctional host to co‐incorporate a PNipam/PAA network and LiCl, creating a high‐performance sorbent for atmospheric water harvesting. The composite achieves rapid sorption, efficient low‐temperature desorption, and stable cycling, enabling a solar‐powered device with a high ...

Mechanically Activated Luminescence in Polyurethanes Incorporating Calixarene Mechanophores

Angewandte Chemie, EarlyView.
The conformational flexibility of a calix[4]arene is exploited to obtain a reversible mechanoluminophore featuring a pyrene excimer couple at the upper rim. Stretching a linear polyurethane incorporating such mechanophore results in luminescence color change from yellow–green to blue, consistent with a force‐induced conformational motion of the ...

Photo‐ and Thermoresponsive Polymersomes for Triggered Release

Angewandte Chemie International Edition, 2012
Microfluidics: Thermo- and photoresponsive polymersomes are assembled using capillary microfluidic devices. Encapsulants can be selectively released from the thermoresponsive polymersomes if they are incubated at and above temperatures of 40 °C, whereas the photoresponsive polymersomes selectively release encapsulants if illuminated with laser light ...
