A new family of organically modified silicates prepared from gels

Effects of hydroxyl groups and architecture of organic polymers on polystyrene/silica nanocomposites

“…Since PHPS is soluble to many organic solvents, such as benzene, xylene, tetrahydrofurane (THF), pyridine, and so forth, organic solutions of PHPS are used for silica coatings. However, the reported maximum thickness of silica coat film by using PHPS solutions was less than 2.2 m due to the drastic shrinkage of coat film owing to the density change from 1.3 to 2.2 g/cm 3 by calcination. Another interesting feature of PHPS is its high reactivity with the hydroxyl group.…”

Hybrid membranes based on SiO2/polyether‐b‐polyamide: Morphology and applications

“…[1][2][3] The inorganic component changes the mechanical and thermal characteristics of the organic matrix as well as the ion conductivity 4,5 and ability of swelling and transporting gases. 6,7 Applications of organic-inorganic hybrids in many fields, such as nonlinear optics, 8 optics and electronics, 9 solid electrolytes, 10 catalysis, 11 biomaterials and biomedical materials, [12][13] and membranes, 14 have been described. In the area of membranes, the introduction of an inorganic component into an organic matrix has been used to improve, for instance, the selectivity of hydrocarbons in silicone membranes.…”

Synthesis, Characterization and Gas Permeability of an Activated Carbon-Loaded PEBAX 2533 Membrane

“…Particle size of the inorganic filler would influence the final properties, which are also controlled by the interfacial interactions between polymer matrix and the inorganic filler. Applications of organic-inorganic hybrids in many fields, such as non-linear optics [3], optics and electronics [4], solid electrolytes [5], catalysis [6], biomaterials [7] and membranes, have been described in the literature. Introduction of an inorganic component into an organic matrix would help to improve the selectivity of hydrocarbons, such as in silicone membranes [8].…”
