Ocular Biocompatibility of Poly-N-Isopropylacrylamide (pNIPAM)

Journal of Ophthalmology, 2016
Purpose. To study the safety of intravitreal injections of poly-N-isopropylacrylamide (pNIPAM) tissue adhesive in rabbit eyes. Methods. Twelve study rabbits received an intravitreal injection of 0.1 mL 50% pNIPAM in the right eye.

Optical and mechanical properties of PNIPAm‐MWCNTs and PNIPAm‐GO composites

Journal of Applied Polymer Science, 2022
AbstractThe aim of this study is to investigate drying, swelling, elastic properties, and to produce optical band gap energies on the performance of Poly (N‐Isopropyl acrylamide) ‐ Multi walled carbon nanotubes (PNIPAm – MWCNTs) and Poly (N‐Isopropyl acrylamide)‐ Graphene Oxide (PNIPAm‐GO) composites, respectively.

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.

Thermo-responsive poly(N-isopropylacrylamide) (PNIPAM) hydrogel particles improve workability loss and autogenous shrinkage in cement paste

Cement, 2022
In this work, we show that non-superabsorbent, thermo-responsive poly(N-isopropyl acrylamide) (PNIPAM) hydrogel particles (< 250 μm) can reduce autogenous shrinkage in cement paste and improve early-age stiffening that can be caused by traditional ...

Controlled surface initiated polymerization of N-isopropylacrylamide from polycaprolactone substrates for regulating cell attachment and detachment [PDF]

, 2012
Poly(ε-caprolactone) (PCL) substrates were modified with thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) brushes to direct and control cellular attachment and detachment. Prior to brush growth, the surface of PCL was activated by a diamine to allow

Surface Morphology at the Microscopic Scale, Swelling/Deswelling, and the Magnetic Properties of PNIPAM/CMC and PNIPAM/CMC/Fe3O4 Hydrogels

Gels, 2016
Poly(N-isopropylacrylamide) (PNIPAM) hydrogels containing carboxymethylcellulose (CMC) and CMC/Fe3O4 nanoparticles were prepared. Free-radical polymerization with BIS as cross-linker was used to synthesize the hydrogels. The morphology at the microscopic
