Kinetics of Light‐Responsive CNT / PNIPAM Hydrogel Microactuators
Small, 2023 AbstractLight‐responsive microactuators composed of vertically aligned carbon nanotube (CNT) forests mixed with poly(N‐isopropylacrylamide) (PNIPAM) hydrogel composites are studied. The benefit of this composite is that CNTs act as a black absorber to efficiently capture radiative heating and trigger PNIPAM contraction.

Responsive Nanocellulose-Pnipam Millicapsules
Journal of Colloid and Interface ScienceMilli- and micro-capsules are developed to facilitate the controlled release of diverse active ingredients by passive diffusion or a triggered burst. As applications expand, capsules are required to be increasingly multi-functional, combining benefits like encapsulation, response, release, and even movement.

Thermosensitive PNIPAM grafted alginate/chitosan PEC [PDF]
Applied Surface Science, 2019 Smart biomaterial functionality such as controlled adhesion properties is crucial to limit strip-off injuries. Among functional polymers, poly-N(isopropylacrylamide) (PNIPAM) allows surface properties to be changed depending on the temperature, with a transition of its properties that occurs around 32 °C, called the lower critical solution temperature (

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels
Advanced Functional Materials, EarlyView.Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

Porous silver-coated pNIPAM-co-AAc hydrogel nanocapsules [PDF]
Beilstein Journal of Nanotechnology, 2019 This paper describes the preparation and characterization of a new type of core–shell nanoparticle in which the structure consists of a hydrogel core encapsulated within a porous silver shell. The thermo-responsive hydrogel cores were prepared by surfactant-free emulsion polymerization of a selected mixture of N-isopropylacrylamide (NIPAM) and acrylic ...
