Compositional and Temperature Effects on the Rheological Properties of Polyelectrolyte–Surfactant Hydrogels
(MDPI, 2019-05-27)
The rheological properties of hydrogels prepared by physical interactions between oppositely charged polyelectrolyte and surfactant in micellar form were studied. Specifically, hyaluronan was employed as a negatively charged ...
How Humic Acids Affect the Rheological and Transport Properties of Hydrogels
(MDPI, 2019-04-19)
Huminové kyseliny jsou považovány za látky s tzv. supramolekulární strukturou, jež je základem jejich unikátních vlastností a fungování v přírodě. Naše studie potvrdila, že již malý přídavek těchto látek do agarozových ...
Multiscale experimental evaluation of agarose-based semi-interpenetrating polymer network hydrogels as materials with tunable rheological and transport performance
(MDPI, 2020-10-31)
This study introduces an original concept in the development of hydrogel materials for controlled release of charged organic compounds based on semi-interpenetrating polymer networks composed by an inert gel-forming polymer ...
The study of the hydrogel systems with micellar nanodomains and the effect of the pH changes on their properties
(TANGER Ltd., 2021-01-01)
Interaction between polyelectrolyte and oppositely charged surfactant leads to a formation of a hydrogel with micellar nanodomains. The main focus of this work was to monitor and study how pH and its changes affect mainly ...
Controlling the internal microstructure and properties of physically cross-linked PVA hydrogels by the rate of freezing
(TANGER Ltd., 2021-01-01)
PVA hydrogels can be formed via physical crosslinking (e.g. by cyclic freezing/thawing of aqueous polyvinyl alcohol solutions) or with a chemical cross-linker. Physical crosslinking is more useful for biomedical applications ...
