Fluoride release from six light-activated restorative materials, including two resinmodified glass-ionomers, two composites, and two compomers, was evaluated and compared with one conventional acid-based glass-ionomer cement. The amount and rate of release varied among the tested materials. Both resin-modified glass-ionomers and the conventional acid-base glass-ionomer cements released more flu...

This article is an updated review of the published literature on glass-ionomer cements and covers their structure, properties and clinical uses within dentistry, with an emphasis on findings from the last five years or so. Glass-ionomers are shown to set by an acid-base reaction within 2-3 min and to form hard, reasonably strong materials with acceptable appearance. They release fluoride and ar...

Poly(ethylene-co-methacrylic acid) (EMAA) ionomers have shown healing capabilities in both ballistic and static tests. In previous studies it was shown that the degree of crosslinking (clusters) affects (positively or negatively) the healing under impact tests. Moreover, it has also been reported that the modification of the ionomers by additives leads to different healing behaviours under stat...

Ionomer thin-films (i.e., 20–100 nm) on supports serve as model systems to understand ionomer-catalyst interfacial behavior well the confinement-driven deviation in properties from bulk membranes. While ionomer have been examined for proton exchange ionomers, thin-film of anion ionomers (AEIs) remain largely unexplored. More importantly, delineating convoluted impact chemistry and confinement m...

Ionomers consist of macromolecules with a few mole percent ionic groups attached to the hydrophobic backbone. The introduction of the ionic groups on a polymer chain can dramatically change the bulk properties, such as the glass transition temperature and miscibility with other materials.1 Most of the past studies of ionomers were concentrated on their rheological properties. In nonpolar solven...

Polyethylene based ionomers are demonstrated to feature a thermo-mechanical and dielectric property portfolio that is comparable cross-linked polyethylene (XLPE), which may enable the design of more sustainable high voltage direct-current (HVDC) power cables, crucial component future electricity grids seamlessly integrate renewable sources energy. A new type ionomer obtained via high-pressure/h...
