Hybrid Inorganic–Organic Polymers Based on Organically Modified Si-Alkoxides

Abstract

REVIEWSHybrid materials have found widespread applications in recent years and are one example for the bottom-up approach to nanotechnology: materials and phases are generated by physical or chemical means from precursor compounds forming nanoscale or nanocomposite materials. This review describes basic principles and several applications of inorganic± organic polymers using organically crosslinked heteropolysiloxanes (ORMOCERs) based on the sequential synthesis of inorganic and organic networks.

Thermal studies: A comparison of the thermal properties of different oligomers by thermogravimetric techniques

“…The concept 2 is to combine properties of organic polymers (functionalization, ease of processing at low temperature and toughness) with properties of glasslike materials (hardness, chemical and thermal stability, and transparency) to generate new/synergistic properties. 2 Thermal properties of two conventional organic monomers, five newly developed organically modified ceramic hybrid materials and one commercially available epoxy resin, were studied and compared. These organically modified ceramics resins contain alkoxides or mixtures of alkoxides of silicone, aluminum, calcium, and titanium.…”

“…The processing steps are based on sol-gel-type reactions, which are already well known for the synthesis of ceramics. 2 In the case of organically modified ceramic hybrid materials, a second step, the formation of the additional organic network or crosslinking, follows after the buildup of the inorganic network. 2 These organically modified ceramic hybrid materials are used in a wide range of applications such as wear-resistant coating, in microelectronics, microoptics, electrooptics, and photonics and as matrices for dental composites.…”

Phosphosilicate–polyamidoamine hyperbranched polymer–Er3+ nanocomposite toward planar optical waveguide applications

“…Recently, silica-gel-based inorganic-organic hybrid materials have found widespread applications [1,2]. Phosphorus materials [3] and some polymers were doped in silica gel to enhance the performance of its hybrid materials to be used in versatile applications as wave guide materials.…”

Biological evaluation of a new organically modified ceramic‐based dental restorative resin

“…Other problems such as uncured organic monomers leaching from the dental composites into the surrounding gum tissue have been reported to cause cytotoxic effects. 1,2 Organically modified ceramic hybrid materials are used in wide range of applications such as wear resistant coating, in microelectronics, micro-optics, electro-optics, photonics as matrices for dental composites, 3 and scaffolds for tissue engineering. 4 Calcium hydroxide, Ca(OH) 2 , was incorporated during resin synthesis, because it is known that Ca(OH) 2 is used as dressing in paste form in dentistry during dental root canal procedure.…”
