Novel ABA type gold copolymer nanoparticles: PNIPAAm-b-PU-b-PNIPAAm tri-block nanopolymer as reducing and stabilizing agent

AIP Conference Proceedings, 2012
Block copolymers have been used extensively in the synthesis of different types of nanoparticles. A novel ABA type tri-block nanopolymer PNIPAAm-b-PU-b-PNIPAAm has been synthesized via atom transfer radical polymerization (ATRP) technique, using a tertiary bromo-terminated as a macroinitiator.

Temperature-Sensitive Nanogels PNIPAAm/DMA Prepared and Research

Advanced Materials Research, 2012
There have much study about thermo-responsive nanogels,which exhibit temperature-controlled volume phase transitions.There have been few reports,however,of electrostatically neutral,thermosensitive nanogels with a high composition of hydrophilic monomer.Here,we describe the synthesis and characterization of a new class of nonionic copolymer nanogels ...

Synthesis and Characterization of TZD Loaded PNIPAAm-b-PU-b-PNIPAAm Tri-Block Gold Nanopolymer

International Journal of Green Nanotechnology, 2012
ABSTRACT Block copolymers have been used extensively in the synthesis of different types of nanoparticles. A novel ABA type PNIPAAm-b-PU-b-PNIPAAm tri-block nanopolymer has been synthesized via atom transfer radical polymerization (ATRP) technique using a tertiary bromo-terminated as a macro-initiator and was characterized by nuclear magnetic resonance

Strategies to improve the response rate of thermosensitive PNIPAAm hydrogels

Soft Matter, 2008
Poly(N-isopropylacrylamide) (PNIPAAm) hydrogel is one of the most extensively studied thermosensitive hydrogels, it displays a lower critical solution temperature (LCST) at around 33 °C in aqueous solution and undergoes an abrupt thermoreversible change in volume as the external temperature cycles around this critical temperature.

Projection micro-stereolithography of temperature responsive PNIPAAm hydrogel

2017
Poly(N-isopropylacrylamide) (PNIPAAm) is one of the most popular temperature responsive hydrogel which is widely used in many research fields. However, the application of PNIPAAm is significantly limited because of lack of suitable three-dimensional (3D) fabrication method.
