Product:DihydrideDouble-Decker Silsesquioxanes(OD-100)
Product Feature :
The product is an organic-inorganic hybrid material. DDSQ structure contains an inorganic core composed of silicon oxide and peripheral organic substitution groups. It has low density, low surface energy, high hardness, high refractive index,high mechanical properties, organo soluble, and compatibility with polymers. Good performance, wear resistance, heat resistance and excellent flame retardant properties. DDSQ can be directly copolymerized with the polymer in the main chain, its performance is better than the traditional monofunctional or multifunctional typePOSS.
Product application:
Semiconductor packaging materials, Flame-resistant materials, Cosmetic materials, Low surface energy materials, Optical materials, Low dielectric materials, Nanolithography materials and self-assembly materials etc.
Organosilicon Compound – Cage series
The incorporation of DDSQ into some polymers has offered the opportunity to develop high performance materials that combine many desirable properties of conventional organic and inorganic components such as good thermal and mechanical properties, solubility, nonflammability, oxidative resistances, and excellent dielectric properties.
Due to the DDSQ possesses precisely two reactive hydrosilane functional groups, linear organic-inorganic nanohybrid polymers can be obtainable without cross-linking reaction.
In most cases, all of the POSS macromers were derivatized with mono- or multifunctionalized monomers and formed only low-molecular-weight Polymer/POSS hybrids. recently several approaches have been tested to result in difunctionalized POSS macromers forming high-molecular weight main-chain-type Polymer/POSS.
