Thermogelable PNIPAM Microgel Dispersion as 3D Cell Scaffold: Effect of Syneresis
Using poly(N-isopropylacrylamide-co-2-hydroxyethyl methacrylate) (P(NIPAM-HEMA)) microgel as an example, we proposed that thermogelable microgel dispersions can be used as a new type of injectable cell scaffolds. However, these in situ formed hydrogels shrink with time, which is undesirable for their use as cell scaffolds. In this work, the syneresis of hydrogels from poly(N-isopropylacrylam...

Lead-Sensitive PNIPAM Microgels Modified with Crown Ether Groups
A series of lead-sensitive poly(N-isopropylacrylamide) microgels with pendant crown ether groups were prepared. Their cation-sensitive behaviors were studied by dynamic light scattering. When ionic strength is not controlled, adding salts causes the microgel particles to deswell. However, when the salt effect is ruled out by keeping a constant ionic strength, adding Pb2+ results in much larg...

PNIPAM Microgels for Biomedical Applications: From Dispersed Particles To 3D Assemblies
Poly(N-isopropylacrylamide) (PNIPAM) microgel is perhaps the most well-known intelligent soft nanomaterial. Combining the strengths of hydrogel and nanoparticles, with unique stimuli-responsivity, PNIPAM microgels have found numerous biomedical applications, such as drug delivery, biosensing, and so on. Usually they were used as dispersed particles, however, they can also be used as buildin...

Synthesis, characterization and the rapid response property of the temperature responsive PVP-g-PNIPAM hydrogel
In this study, a poly(N-vinylpyrrolidone)-graft-poly(N-isopropylacrylamide) hydrogel
(PVP-g-PNIPAM) was synthesized through the ‘‘grafting from” process. Grafting of temper-
ature responsive poly(N-isopropylacrylamide) (PNIPAM) brushes was carried out from the
poly(N-vinylpyrrolidone) (PVP) synthesized with free radical polymerization and function-
alized with ATRP initiator,...

Effects of inorganic cross-linker content on the temperature- sensitivity of PNIPAM microgels
A new method, adopting inorganic clay (synthetic hectorite) as a physical cross-linker, was used to prepare poly(N-isopropylacrylamide) (PNIPAM) microgels via surfactant-free emulsion polymerization. The effect of hectorite content on the
temperature-sensitivity of PNIPAM microgels was investigated by means of DLS, UV/Vis and DSC. It was found that, in the absence of surfactant, with increasing h...

Phase Transition and Micellar Aggregation Behavior of PS-b-PNIPAM in Organic Solvent-water Solutions
关键字：Phase,Transition,Micellar,Aggregation,Behavior,PNIPAM,Organic,Solvent,water,Solutions,
Poly (N-isopropylacrylamide) (PNIPAM) is a typical example of smart polymers, which exhibits a well-known lower critical solution temperature (LCST) in water and its conformation changed by adjusting temperature.

振荡剪切流变学研究 PNIPAm 微凝胶的 Jamming 转变
关键字：PNIPAm 微凝胶，Jamming，振荡剪切流变
Jamming 是粒子分散体系浓度变化过程中的普遍现象，对非晶玻璃化转变的研究具有重要的借鉴意义。聚(N-异丙基丙烯酰胺)（PNIPAm）微凝胶由于温敏性，可以通过改变温度 T或悬浮液中的粒子重量浓度 w 来实现固-液转变。本工作利用流变学研究了 PNIPAm 微凝胶悬浮液的 jamming-unjamming 转变。动态温度扫描结果表明：发生 unjamming 转变的临界温度Tc随 w 的增加而升高...
