Preparation of poly(methyl acrylate-co-itaconic anhydride)/SiO2 hybrid materials via the sol-gel process?The effect of the coupling agent, inorganic content, and nature of the catalyst

Phase structure and thermomechanical properties of primary and tertiary amine‐cured epoxy/silica hybrids

“…In the first case, the polymer molecules are dispersed in the silica network by the formation of a hydrogen bond between the basic group of the hydrogen acceptor in the polymer and the silanol group of the intermediate species from the silane alkoxide 6, 7. Another case is the formation of a covalent bond between the polymer and silica network 8–10. In the hybrid systems cured with TEPA, it is expected to form the hydrogen bond between the hydroxyl group in the polymer and the silanol group.…”

“…Chujo et al6, 7 reported that the hybrids of an inorganic silica network with organic polymers, which could form hydrogen bonding between the inorganic and organic components, produced homogeneous and transparent glassy materials. In addition, the organic–inorganic hybrids that form a covalent bond between the organic and inorganic phases have been actively studied by many investigators 8–10. We also reported covalently bonded organic–inorganic hybrid materials prepared with bisphenol A‐type epoxy resin and 3‐glycidoxypropyltrimethoxysilane (GPTMS) 11, 12.…”

Vinyltriethoxysilane Functionalized Graphene Oxide/Polyvinyl Alcohol Nanocomposites Films with Improved Oxygen and Water Barrier Performance

“…The interaction of organic and inorganic phases of these hybrid films impacts the quality of these films. By fostering strong interfacial adhesion between the two phases, hybrid materials can achieve a stable homogenous nanophase and improved material properties [24][25][26][27].…”

Preparation and barrier property of poly(vinyl alcohol)/SiO2 hybrid coating films

“…It is expected that when strong interfacial adhesion between two phases is formed, the hybrid materials exhibit stable homogeneous microstructure without macro-phase separation and improved material properties. Hence, in order to enhance interfacial adhesion in hybrid materials, silane coupling agents, which can result in physical or chemical covalent bonding between organic and inorganic phases, have been employed during the sol-gel process [13][14][15][16][17]. Interfacial adhesion may be also enhanced without silane coupling agents by forming physical bonding such as hydrogen bonding between functional groups of organic segments and silanol groups of the silicate network.…”
