Confined Microenvironments from Thermoresponsive Dendronized Polymers

Macromolecular Rapid Communications, 2020
AbstractConfined microenvironments in biomacromolecules arising from molecular crowding account for their well‐defined biofunctions and bioactivities. To mimick this, synthetic polymers to form confined structures or microenvironments are of key scientific value, which have received significant attention recently.

Functionalization of Textiles with Thermoresponsive Polymers

Journal of Fashion Technology & Textile Engineering, 2018
Functionalization of textiles with thermoresponsive polymers is the aim of this research work. Therefore, suitable textile substrates had been selected and characterized with the aid of a skin model regarding the water vapor resistance. A novel modified cup method was optimized for detecting the thermoresponsive behavior of the synthesized polymer ...

Synthesis of Thermoresponsive Polymers for Drug Delivery

2014
A protocol for synthesizing thermosensitive copolymers of N-isopropylacrylamide (NIPAM) and N-vinylpyrrolidone (VP), cross-linked with N,N'-methylene-bis-acrylamide (MBA) has been described in this chapter. The copolymers have been formed at different concentrations of NIPAM and VP and at two different temperatures (70 °C and 30 °C). The lower critical

Patterned Immobilization of Thermoresponsive Polymer

Langmuir, 1997
The thermoresponsive polymer poly(N-isopropylacrylamide) was immobilized in a specific pattern on a polystyrene matrix by photolithography. N-Isopropylacrylamide was copolymerized with acrylic acid. The copolymer was coupled with azidoaniline. The low critical solution temperature of the copolymer was lowered by incorporation of azidophenyl groups. The

Microalgae aggregation induced by thermoresponsive polymers

Bioresource Technology
Algal 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 ...

Preparation of thermoresponsive and easily functional polymer brushes and their thermoresponsive properties

SCIENTIA SINICA Chimica, 2014
Thermoresponsive materials have overwhelming development prospects because of their excellent properties and widely potential applications. The polymer brushes of poly(MEO2MA- co -OEGMA526) were prepared by the copolymerization of 2-(2-methoxyethoxy)ethyl methacrylate (MEO2MA) and poly(oligo(ethylene glycol) methacrylate) (OEGMA526) on the gold surface

Magnetic Nanoparticles Encapsulated Within a Thermoresponsive Polymer

Journal of Nanoscience and Nanotechnology, 2009
This 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.

Thermal Switching of Thermoresponsive Polymer Aqueous Solutions

ACS Macro Letters, 2017
Thermal 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 ...

Switching between Polymer Architectures with Distinct Thermoresponses

Macromolecular Rapid Communications, 2017
Thermoresponsive 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.
