Magnetic Nanoparticles Encapsulated Within a Thermoresponsive Polymer
Journal of Nanoscience and Nanotechnology, 2009This study describes a facile two-step approach to modify the surface of nanoparticles, thereby imparting a core-shell structure to the system. The core consists of magnetic nanoparticles and the shell is composed of thermoresponsive hydroxypropyl cellulose, using a coupling agent to covalently bind the core to the shell.

Microalgae aggregation induced by thermoresponsive polymers
Bioresource TechnologyAlgal biomass harvesting is one of key technical hurdles impeding the commercialization of algae-based biorefinery. The goal of this work is to develop an innovative technology for algae cell harvesting. Thermoresponsive polymers (TRPs) such as poly(N-isopropylacrylamide) (PNIPAM) and its derivatives were studied on their properties and potential ...

Switching between Polymer Architectures with Distinct Thermoresponses
Macromolecular Rapid Communications, 2017Thermoresponsive linear polymers and their corresponding aggregates or nanogels typically show similar thermoresponsive profiles. In this study, the authors demonstrate reversible chemical switching between linear polymers and their cross-linked nanogels.

Thermoresponsive polymer-modified microfibers for cell separations
Acta Biomaterialia, 2017Thermoresponsive polymer-modified microfibers were prepared through electrospinning of poly(4-vinylbenzyl chloride) (PVBC) and subsequent surface-initiated atom transfer radical polymerization for grafting poly(N-isopropylacrylamide) (PIPAAm). Electrospinning conditions were optimized to produce large-diameter (20μm) PVBC microfibers.

Thermal Switching of Thermoresponsive Polymer Aqueous Solutions
ACS Macro Letters, 2017Thermal switches are of great importance to thermal management in a wide variety of applications. However, traditional thermal switches suffer from being large and having slow transition rates. To overcome these limitations, we took advantage of abrupt second-order phase transitions in thermoresponsive polymer aqueous solutions to enable fast thermal ...

Thermoresponsive AuNPs Stabilized by Pillararene‐Containing Polymers
Macromolecular Rapid Communications, 2015Pillararene‐containing thermoresponsive polymers are synthesized via reversible addition–fragmentation chain transfer polymerization using pillararene derivatives as the effective chain transfer agents for the first time. These polymers can self‐assemble into micelles and form vesicles after guest molecules are added.
