Behavior of PNIPAM Microgels in Different Organic Solvents
Molecules, 2022 In this research, we studied, in detail, the behavior of common PNIPAM microgels, obtained through surfactant-free precipitation polymerization, in a number of organic solvents.

Porous thermo-responsive pNIPAM microgels
European Polymer Journal, 2015 Abstract Thermo-responsive poly(N-isopropylacrylamide) (pNIPAM) gels are very attractive for biological applications due to a phase transition at temperature (32 °C) closed to that of biologically relevant. This stimulates the usage of this polymer for cell culture, biosensing, drug delivery, etc. Herein we develop a new simple approach to synthesize

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows [PDF]
Advanced Science, EarlyView.We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

The Double-Faced Electrostatic Behavior of PNIPAm Microgels [PDF]
Polymers, 2021 PNIPAm microgels synthesized via free radical polymerization (FRP) are often considered as neutral colloids in aqueous media, although it is well known, since the pioneering works of Pelton and coworkers, that the vanishing electrophoretic mobility characterizing swollen microgels largely increases above the lower critical solution temperature (LCST ...

Thin films of PS/PS‐b‐pnipam and ps/pnipam polymer blends with tunable wettability [PDF]
Journal of Polymer Science Part B: Polymer Physics, 2019 ABSTRACTWe developed thin films of blends of polystyrene (PS) with the thermoresponsive polymer poly(N‐isopropylacrylamide) (PNIPAM) (PS/PNIPAM) and its diblock copolymer polystyrene‐b‐poly(N‐isopropylacrylamide) (PS/PS‐b‐PNIPAM) in different blend ratios, and we study their surface morphology and thermoresponsive wetting behavior.

Microfluidic devices functionalized with PNIPAm [PDF]
, 2021 In this thesis, we developed several PDMS-based microfluidic devices for emulsion generation and capillary-driven flow control. By grafting the PDMS surface with PNIPAm using UV-induced surface polymerization, we obtain a PNIPAm-g-PDMS surface with it's surface wettability that is sensitive to temperature.
