Effects of water adsorption in hydrophilic polymers
The origin of the adsorption-induced phenomena in hydrophilic polymers, such as cellulose, lies at the atomistic scale. We use molecular dynamic simulations to investigate the mechanisms by which the adsorbing polymers change their properties upon water adsorption. Despite of their limited spacial and temporal capabilities MD simulations are able to reproduce the hygroscopic swelling and moistu...
متن کاملHydrophilic Natural Polymers for Sustained-controlled Release of Calcium Hydroxide
Calcium Hydroxide (CH) is commonly employed as intracanal medicament in endodontics. In order to maximize its therapeutic effects, it is essential to develop new approaches for preparing the controlled drug release systems which, in turn, facilities the dissociation of CH into calcium and hydroxyl ions. This work studies the sustained-controlled release of calcium ions and the effect of pH chan...

متن کاملUniversal features of water dynamics in solutions of hydrophilic polymers, biopolymers, and small glass-forming materials.
A systematic investigation by dielectric spectroscopy of 18 different water-rich mixtures with very different hydrophilic substances shows universal features for the water dynamics. The temperature dependence of the relaxation times exhibits a crossover from non-Arrhenius to Arrhenius behavior at the T(g) range of the mixtures. Furthermore, the temperature dependence of the relaxation times pre...
متن کاملRigid hydrophilic structures for improved properties of conjugated polymers and nitrotyrosine sensing in water.
The efficient synthesis of a hydrophilic monomer bearing a three-dimensional noncompliant array of hydroxyl groups is described that prevents water-driven excimer features of hydrophobic poly(p-phenylene ethynylene) backbones. Sensitivity of the polymer to 3-nitrotyrosine is also discussed.
