Gelation of a Nanocomposite-Hydrogel System and Its Dependency on Mechanical Loads

Applied Rheology, 2017
Hydrogels are cross-linked polymer networks which are water-insoluble. They are suitable for several technical and biomedical applications due to the ability of some gels to swell and deswell as reaction to external stimuli. Such gels are synthesized and

Dual Stimuli-Triggered Nanogels in Response to Temperature and pH Changes for Controlled Drug Release

Nanoscale Research Letters, 2019
Poly-N-isopropyl acrylamide (PNIPAM) nanogels have been modified with different acrylic acid (AAc) contents for the efficient control of lower critical solution temperature (LCST).

The Study of Release of Chlorhexidine from Preparations with Modified Thermosensitive Poly-N-isopropylacrylamide Microspheres

The Scientific World Journal, 2012
The aim of this study was to investigate and compare the release rates of chlorhexidine (CX) base entrapped in the polymeric beads of modified poly-N-isopropylacrylamides (pNIPAMs) at temperatures below and over the volume phase transition temperature ...

Responsive Nanocellulose-Pnipam Millicapsules

Journal of Colloid and Interface Science
Milli- 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.

Thermo-responsive PNIPAM nanofibres crosslinked by OpePOSS

, 2013
Stable and re-usable thermo-responsive hydrogel nanofibres were produced by electrospinning poly(Nisopropylacrylamide) (PNIPAM) in presence of a polyhedral oligomeric silsesquioxane (POSS) possessing eight epoxide groups, and of a 2-ethyl-4 ...

Tacticity-Dependent Interchain Interactions of Poly(N-Isopropylacrylamide) in Water: Toward the Molecular Dynamics Simulation of a Thermoresponsive Microgel

Gels, 2017
The discovery that the lower critical solution temperature (LCST) of poly(N-Isopropylacrylamide) (PNIPAM) in water is affected by the tacticity opens the perspective to tune the volume phase transition temperature of PNIPAM microgels by changing the ...
